The Aqueduct extension for Mediawiki

+ +

The Aqueduct extension for Mediawiki provides several services. The extension allows the administrator to define a mapping between wiki pages and URIs. The administrator must also specify where the data for the URIs is located and how it can be retrieved.

+ +

The Aqueduct extension allows for the creation of wikis where users visualize, analyze, discuss, and enhance semantic data. In a way, the wiki acts as a "lens" into semantic data. This semantic data typically resides outside of the wiki, and can be scattered across multiple datasources and servers. The extension does not copy any data into the wiki; instead, it dispatches requests for external semantic data to the proper server and datasource.

+ +

Because data can be scattered across multiple datasources and servers, Aqueduct introduces the concept of "RDF sources". An "RDF source" defines how the triples for a collection of data can be retrieved, and how the URIs for the data can be mapped into the wiki.

+ +

To ensure that semantic data can be located unambiguously, Aqueduct defines a mapping between the titles (or "name") of wiki pages and the URIs that they describe. Therefore, the set of possible titles must be partitioned up such that any given title is associated with no more than one URI and RDF source. This is done by associating Mediawiki namespaces with Aqueduct RDF sources. Mediawiki namespaces allow two pages with the same title to be created, as long as they are in different namespaces. By associating RDF sources with namespaces, the same title can be used to describe several URIs, as long as each URI ends up in a different namespace.

+ +

This extends the "lens" analogy -- the wiki acts as a lens into multiple sources of semantic data, and these sources are "projected" into the wiki, in a manner such that they do not overlap.

+ + +

Understanding RDF Sources

+ +

RDF sources are a key concept in Aqueduct because all data manipulated in Aqueduct flows from an RDF source.

+ +

Aqueduct allows users to place data visualization widgets in wikis in order to visualize RDF data. Aqueduct allows different widgets to simultaneously visualize RDF data that comes from several sources. Data can reside on an external server, on the same server as the wiki, or even within the wiki itself. Aqueduct supports the following RDF sources:

+ + + +

Configuring the Aqueduct extension

+ +

To configure the Aqueduct extension, you must create RDF sources for the data that will be made available through the wiki.

+ +

To configure an RDF source, you must fill the following columns:

+ + + +

More on the test RDF source

+ +

The test RDF source allows you to test Aqueduct without being connected to a Blackbook data source. SSL and browser certificates are not required. This helps ensure that the widgets are working as intended.

+ +

The following URIs are defined in the test RDF source:

+ + + +

To enable the test RDF source for a namespace, create a datastore with a type of Test. The other settings can be set however you want; however, it will be easiest to access the test data if you set them as follows:

+ + + +

If you used the above settings, you will be able to put widgets on pages called "Chicago", "Gary", and "Skokie" (in the namespace that you created).

+ +

The Aqueduct widgets

+ +

Once you have the RDF sources set up for the Aqueduct extension, you can place Aqueduct widgets on wiki pages. Aqueduct widgets are potentially interactive controls that allow the user to visualize the RDF associated with a wiki page.

+ +

To place a widget on the page, insert the name of the widget surrounded by angle brackets. For example, entering <aqRawWidget> or <aqTableViewWidget> will show the Raw RDF or the Table widget. Each widget will visualize the same data in a different way.

+ +

Widgets have no parameters and cannot be configured. Each widget automatically displays the data for the URI associated with the wiki page where it was placed.

+ +

The following widgets currently exist:

Including widgets in another page 

+ +

Note that the above setup only allows the widgets to display data associated with the page where they are placed. This means that all widgets on the page will be displaying the same data. Because this is not always desirable, the user can insert the aqIncludeWidgets tag, which includes widgets from other pages (which will be display different data.)

+ +

To use this tag, specify the title of the page with the widgets that you want to include like this: <aqIncludeWidgets>Namespace:PageTitle</aqIncludeWidgets>. All the widgets on the specified page will be inserted in place of the inclusion tag. They will be rendered exactly as they appeared in the page that is being included, with the same data that would have appeared when directly navigating to that page.

+ +

The aqIncludeWidgets tag can be used recursively to build "building blocks" that will include several widgets from multiple sources. The aqIncludeWidgets tag will behave in the same way when used recurisvely -- whatever widgets appear on the included page will also appear in the page that uses the tag, regardless of where the widgets originally came from.

+ +

Mediawiki templating (using the {} curly braces) will not behave as expected because the widget tags will be considered part of the including page, and they won't use the data of the page where they appeared. However, using templates can still be useful because commonly used collections widget tags can be "aliased" as a template to make them easier to type.

+ +

Combining data from multiple sources

+ +

The feature above allows you to display several widgets on a page with different data in each, but they still don't allow you to combine data from multiple entities or queries into one widget.

+ +

To do this, use the aqAddData tag, which takes all RDF data from the specified entity and causes it to be "merged" with the current entity. Although the data is not modified in Blackbook, this feature causes Aqueduct to treat the two entities as one. As far as Aqueduct is concerned, the specified data becomes a part of the entity corresponding to the page where you used the aqAddData tag.

+ +

To use the aqAddData tag, use the following syntax: <aqAddData>Namespace:PageTitle</aqAddData> . Note that the specified wiki page need not exist, as long as there is semantic data associated with the page title. The aqAddData tag can also be used recursively.

+ +

Note that, unlike with the aqIncludeWidgets tag, the aqAddData tag also affects the behavior of the API, and API consumers will see the merged data. Also note that aqAddData can be used to include queries (advanced RDF source pages) as well as simple RDF entities.

+ +

There are two main use cases for the aqAddData tag:
+1. You can build a "virtual entity" by merging the data from several other entities together and treating it as one. To do this, create a page with several aqAddData tags on it. The page should be outside of an Aqueduct namespace (there shouldn't be any semantic data associated with the page until you add the aqAddData tags.) This "virtual entity" can then be used in the same way as any other entity -- you can put widgets on it, include the widgets in other pages by using aqIncludeWidgets, and even recursively merge the virtual entity into other pages by using the aqAddData tag again.

+ +

2. You can "augment" the data for an entity by including other data that you know is relevant to it. To do this, browse to the page for an entity and use aqAddData to include the data that is deemed relevant. At this point, any other pages that use aqIncludeWidgets or aqAddData to reference the entity will also see the data that you associated.

+ +

Embedding data in the wiki (wiki as a data source)

+ +

It is often useful to store RDF data directly in the wiki, allowing the wiki to act as a both a datasource and a data display system.

+ +

Aqueduct provides functionality allowing the user to embed RDF triples in a special namespace, with wiki pages representing entities (in the same way that page represent entities when querying other datasource). When Aqueduct needs to materialize an entity, it scans the corresponding page for triples and returns them.

+ +

This functionality is distinct from any Semantic Mediawiki support Siphon provides. Embedding triples with Semantic Mediawiki requires the user to have a copy of Semantic Mediawiki and a Blackbook instance to receive the triples. In this case, Aqueduct queries Blackbook for the desired entities, instead of reading the wiki pages.

+ +

Using the Semantic Mediawiki and Siphon approach has the advantage of enabling advanced queries and the use of any algorithm that Blackbook supports. The Embedded Data support being discussed in this section does not support algorithms or advanced queries.

+ +

The advantage of the Embedded Data support discussed here is that neither Semantic Mediawiki or Blackbook is required. Also, the semantic data is available instantly, without waiting for Siphon to process it. 

+ +

To embed triples in the wiki, create an RDF source with a datastore type of "Embedded" and choose a datastore URI prefix. Aqueduct will then allow you to embed triples in this namespace. The subject of the triples are implied by the datastore URI prefix and the page title where the triples are placed, while the predicate and object are specified explicitly.

+ +

Basic triple embedding

+ +

To embed a triple into a wiki page in a namespace that was set up for triple embedding, use the following syntax:

+
+
{{#triple:predicateuri|object|objecttype}}
+
+

"predicate" is the predicate URI for the embedded triple. "objecttype" is "literal" or "uri". "object" is the object of the embedded triple.
+ +You can also create templates (or parameterized templates) that call the "triple" tag. When the user embeds this template into their wiki page, it will add the triple(s) present in the template. This allows you to define your own syntax that users can use to embed triples into wiki pages. Because the default syntax is non-intuitive, creating customized triple templates is the way that this feature was intended to be used.

+ +

Advanced triple embedding

+ +

It is also possible to embed a triple on a page that doesn't correspond to the URI of the triple. This allows you to have a single wiki page that contains triples that refer to different entities, possibly making maintenance of the data easier.

+ +

For this to work, your URIs must be constructed as follows:

+
    +
  1. All of the URIs should contain a "common prefix", followed by a hash mark, and then a suffix that distinguishes them.
    2. +
  2. The URIs should only have a single hash mark each.
    3. + +
  3. The URIs should be associated with a basic RDF source of the "embedded" type, where the "Datasource URI prefix" some prefix of the "common prefix".
    4. +
  4. Triples should be stored on a wiki page in the appropriate namespace, with the title of the page constructed so the page's URI equals the "common prefix". This page will be called the "base page".
    5. +
  5. Triples for each subject can be viewed on "fragment pages", which have wiki titles that correspond to the URIs of the subjects. Note that because hash marks are translated into backslashes () when constructing wiki title, all fragment pages will have a backslash somewhere in the title.
    6. +
  6. Triples can also be embedded on the fragment pages themselves. Triples from the base page and triples from the fragment pages will be merged when retrieving data for the fragment pages.
    7. +
  7. The "Search for Fragments" parameter must be set to 1 in the configuration page. Otherwise, the base page will not be checked when viewing the fragment page.
    8. +
+ +

The syntax for advanced triple embedding is as follows:

+
+
{{#triple:predicateuri|object|objecttype|fragment}}
+
+

Where "fragment" matches everything that comes after the hash mark in the URI that is to be represented. (Note that this syntax should only be used on the base page, and the basic triple embedding syntax should be used on the fragment pages.

+ +

An example:

+ +

Create an RDF source with settings: name "EmbedTest", URI prefix "uri:embedded:", type "Embedded", search for fragments "1", title initial lowercase "0".
+Create a page called "EmbedTest:People". Add

+ +
+
{{#triple:uri:embedtest:firstname|Jeff|literal|jeff}}
+
+

Create a page called  "EmbedTest:People\jeff". Put a table widget on the page. The "firstname" triple created on the base page will appear.

+ +

Advanced RDF sources 

+ +

You can also defined "Advanced RDF sources" and associate them with Mediawiki namespaces. This allows you to create wiki pages that are associated with the results of more complex queries or algorithm executions.

+ +

To configure an Advanced RDF source, you must fill in the following columns:

+ + + + +

More on namespaces and RDF sources 

+ +

Mediawiki internally uses the Namespace ID of a page when storing pages in the database, but links to pages (and other cached information) uses the namespace name. For this reason, it is important that once pages have been created within a particular namespace, the ID of that namespace continues to refer to the same namespace name until all pages in the namespace have been deleted.

+ +

When you define a namespace as a basic or advanced RDF source, Aqueduct will automatically set up the corresponding Mediawiki namespace so wiki pages can be named. If you remove the basic or advanced RDF source at a later date, and if the RDF source already contains pages, Aqueduct will maintain a memory of the namespace, and continue to maintain the namespace even though it no longer corresponds to an RDF source, in order to prevent previously created pages from becoming accessible.

+ +

For this reason, if you create a namespace with a particular namespace ID or name, and later delete the namespace after creating pages in it, Aqueduct will no longer allow you to create another RDF source with the same namespace ID or name, unless BOTH the namespace ID and name match the previous ones. 

+ +

Parameterized queries 

+ +

The double hash mark (##) is used as a placeholder for a parameter in the "query text" for an advanced RDF source. This allows you to define an entire namespace of queries, where each page represents one value that the parameter could take on.

+ +

If "Use URI as Query Parameter" is set to 0, the placeholder is replacedwith the title of the page (unescaped, and minus the namespace). If it's set to 1, the title is converted to a URI (for this purpose, it is assumed to be in the Associated Namespace of the Advanced RDF Source), and then the URI is used instead of the placeholder.

+ +

Manually specifying inline queries for widgets

+ +

It is sometimes useful to explicitly specify SPARQL queries (or similar queries) on the same page where the query will be used, instead of specifying them in the advanced namespace configuration. Aqueduct has an <aqAddQuery> tag that allows this.

+ +

A query added with the <aqAddQuery> tag has several characteristics:

+
    +
  1. In the tag's parameters, the user enters the same information that would be entered when configuring an advanced RDF source. This causes the current page to function as if it was part of an advanced RDF namespace.
    2. +
  2. If the page is already part of a basic or advanced RDF source, the results of the query will be merged with the page's other data, in the same way that the aqAddData merges triples.
    3. +
  3. If one page draws data from an aqAddQuery tag, the aqAddData tag can include the resulting data from another page. In short, the aqAddData tag still works as expected.
    4. +
  4. If the aqAddQuery page is used in a template, the query will only be performed after the template is expanded, allowing you to create templates that represent commonly-used queries.
    5. + +
  5. A parameterized query can still be performed when the query is defined with the aqAddQuery tag. For the purposes of the query, Aqueduct acts as if a new implicit advanced RDF namespace has been created, and the page being rendered is part of this implicit namespace. The page name can then be used to fill in a query parameter.
    6. +
+ + +

The aqAddQuery tag has the following parameters. All parameters should be specified:

+ + + +

Aqueduct Page Auto-Population

+ +

When following links to wiki pages that have a known mapping to a URI but do not yet exist, it is useful to be able to view the data for the URI without having to create a page with an Aqueduct widget on it every time. For this purpose, Aqueduct provides an auto-population utility.

+ +

This utility automatically activates if a link is followed to a wiki page that both does not exist and resides in a namespace configured through Aqueduct. If these two conditions are met, the utility searches for a Mediawiki template page to use to auto-populate the page. This template is chosen through a specific naming convention. There are two ways to configure auto-population: generically and specifically. If the page already exists, or if the page is in a namespace that is not configured by Aqueduct, then Mediawiki continues normally.

+ +

The generic configuration will be used to auto-populate any page that is created in an Aqueduct namespace. To configure this, a Mediawiki template must be created with the name "Template:Namespace", where "Namespace" is the namespace name you wish to auto-populate. Afterwards, any page created that has the name "Namespace:Page_Title", will be prepopulated with the contents of "Template:Namespace".

+ +

The specific configuration refers to the RDF type of the uri which a page maps to. It will be used to auto-populate any page created in an Aqueduct namespace that matches a given RDF type. To configure this, a Mediawiki template must be created with the name "Template:Namespace:Entity", where "Namespace" is the namespace name and "Entity" is the RDF type of the pages you wish to prepopulate. Multiple specific configurations can be created for multiple RDF entities within a single namespace.

+ +

If both a generic and a specific configuration exist for a namespace, then the specific configuration takes priority, but only when the RDF type matches. If only specific configurations exist for a namespace, then any page not matching a configuration will be treated as a normal Mediawiki page.

+ + +

Grid layout mode

+ +

By default, Aqueduct does not affect the layout of ordinary wiki pages. Widgets appear on wiki pages wherever the corresponding tags are placed. Optionally, the system administrator can enable grid layout mode, in order to change the page layout.

+ + +

When Aqueduct is switched to grid mode, all wiki pages are laid out in a "window pane" mode, similar to how Visual Studio or Eclipse display multiple views inside a single window. The screen is divided into up to 5 panes -- center, west, east, north, and south. These panes can be further subdivided in order to display any number of panes on the screen. Each pane will display exactly one widget, except for the pane that displays the ordinary wikitext. In grid mode, the location of the widget tags within the wikitext becomes irrelevant, because widgets are removed from the normal flow of wikitext and placed into their own grid panes.

+ +

To enable grid mode, you must perform the following steps:

+
    +
  1. Copy or link GridBook.php from the AqueductExtension directory to the wiki's "skins" folder.
    2. +
  2. Edit LocalSettings.php and set $wgDefaultSkin = 'gridbook'
    3. + +
+ + +

After following these steps, every page in the wiki will switch to the grid mode.

+ +

If no further change are made, Aqueduct will automatically choose grid panes and place the widgets and wikitext inside them. This will not be desirable in most cases, and most users will want to manually specify the location and size of the widget panes. The following parameter can be passed to any widget, in order to influence how the widget is rendered:

+ + + +

On pages where widgets are displayed, the position of the wikitext pane must also be specified. To specify this, add the <aqWikiText/> widget to the page, and then specify the position and size of the widget as normally done. Only one <aqWikiText/> widget may be added to a page at once, and this widget has no effect when the grid layout mode is turned off.

+ + +

When using the grid layout mode, watch out for the following:

+ + +

Customizing Aqueduct pages 

+ +

Aqueduct has several features that allow users to embed custom widgets in pages or add custom Javascript to pages. This can be used to create new and customized views of data, or to add Javascript functionality that is not associated with a particular widget.

+ +

Allowing use of these functions may be a security risk. These features are disabled by default because malicious users are allowed to use them, which allow arbitrary HTML and Javascript to be injected into pages that ordinary users see, potentially allowing passwords or other information to be stolen. (When these features are disabled, Aqueduct is designed to foil such attacks.)

+ +

To allow the use of the aqLayoutWidget tag, set the $wgEnableLayoutWidgets = TRUE; configuration option in LocalSettings.php.

+ +

To allow the use of custom headers and scripts, set the $wgEnableCustomScripts = TRUE; configuration option in LocalSettings.php.

+ +

Custom data layouts

+ +

Custom data layouts allow users to display RDF data in their own format, without using any of the built-in widgets (such as the table widget or network view widget). This essentially has the effect of creating a custom widget, although creating a custom layout affords less functionality than writing a full-fledged widget.

+ +

Using a custom data layout is a two-step process. First, add a aqLayout tag which contains the layout definition. Then, add a aqLayoutWidget tag to actually construct a widget that uses that layout definition to display the data. Layout definitions do not specify the data to be displayed (this is specified in the usual way) -- they only specify how to display it.

+ +

It is recommended that the aqLayout and aqLayoutWidget tags be used in pairs, and that they be placed inside a Mediawiki template. This allows users to easily insert the custom widget onto pages as if it was an ordinary widget. Because the aqLayoutWidget tag automatically uses the layout from the last aqLayout tag that was included, it is possible to put the aqLayout and aqLayoutWidget tags in different places, and then use Mediawiki templates or widget inclusion to ensure that the aqLayoutWidget tag is processed after the corresponding aqLayout tag. However, this usage is confusing.

+ +

The custom data layout templating language

+ +

Aqueduct data layouts are written in the jtemplates language. Documentation on the language can be found here: http://jtemplates.tpython.com/

+ +

Templates are written by interspersing HTML with templating directives. Most templating directives either (1) cause the HTML parser to "loop" and repeat an element for each record, or (2) insert the value of a field in place of the directive.

+ +

The following directives will be useful to the template author:

+ +

Begin a foreach loop, looping through each result entity (subject).

+
+
{#foreach $T as record}
+
+

End the foreach loop

+
+
{#/for}
+ +
+

Insert an href tag which causes a link to the current entity to be created (note: jtemplates incorrectly htmlencodes the link, meaning that the link will not work if your wiki URL contains an ampersand for some reason.)

+
+
<a href='{$T.record.mylink}'>
+
+

Inserts the wiki title of the current entity

+
+
{$T.record.myvalue}
+
+

Inserts object that the current entity has for predicate "uri:mypredicate"

+
+
{$T.record['uri:mypredicate'].value}
+ +
+

Inserts a link to the wiki page for the current entity's object for predicate "uri:mypredicate" (this only makes sense if the object is a uri.)

+
+
<a href='{$T.record['uri:mypredicate'].value}'>
+
+

If the desired predicate has multiple values, you should always use the following looping forms to ensure that the expected results are seen:

+ +

Begins looping through all values for predicate "uri:mypredicate" for the current entity.

+
+
{#foreach $T.record['uri:cityschema:HasNeighbor'].all as n}
+
+

Inserts the wiki link or object value for the current object when looping through predicate values

+ +
+
<a href='{$T.n.link}'>
+{$T.n.value}
+
+ +

Example of a custom data layout template

+ +

The following example applies a custom layout to data from the built-in Test RDF source that was described previously.

+
+
<aqLayout>
+<strong>CITY INFORMATION LIST  </strong>
+
+<ol>
+   {#foreach $T as record}
+   <li>
+   <ul>
+   <li>
+   City name: <a href='{$T.record.mylink}'>{$T.record.myvalue}</a>
+
+   </li>
+   <li>
+   Population: {$T.record['uri:cityschema:Population'].value}
+   </li>
+   <li>
+   List of neighbors:
+   <ol>
+
+      {#foreach $T.record['uri:cityschema:HasNeighbor'].all as n}
+      <li><a href='{$T.n.link}'>{$T.n.value}</a></li>
+      {#/for}
+   </ol>
+   </li>
+
+   </ul>
+   </li>
+   {#/for}
+</ol>
+</aqLayout>
+<aqLayoutWidget/>
+
+ +

Custom headers

+ +

The aqAddHeader tag allows users to include arbitrary Javascript files in pages. The Javascript file will be included as in "script src" on the top of the tag. This can be used to include libraries that Javascript code embedded in custom layouts will call.

+ + +

To include a custom header, add a tag like this:

+ +

<aqAddHeader>http://host/file.js</aqAddHeader> 

+ +

Custom scripts

+ +

The aqAddScript tag is similar to the aqAddHeader tag, but the Javascript is added literally instead of being included from another file. The script will be placed in the head of the HTML file.

+ +

To include a custom script, add a tag like this:

+ +

<aqAddScript>

+ +

alert('hello'); 

+ +

</aqAddScript>

+ +

The Blackbook Memcached cache

+ +

Sometimes, when Blackbook as an RDF source, it is desirable to cache the results of Blackbook queries in a faster database to improve performance. Aqueduct supports the use of Memcached, a 3rd-party caching server, to cache the results of these queries. All queries will be cached if this feature is enabled (basic and advanced operations.)

+ +

To enable this caching:

+ +

1. Install the memcached, zlib1g (for compression), and php5-memcache packages.

+ +

2. Restart your webserver to finalize the installation of the php memcache class.

+ +

3. Place these three configuration lines in the LocalSettings.php file:

+
+
$aqMemcacheHost = 'localhost';
+$aqMemcachePort = '11211';
+$aqMemcacheExpirationTime = 600;
+
+

The third line controls how long a key sits in the cache before expiring. The value is in seconds and cannot be over 30 days. If the value IS over 30 days, memcached will treat it as a Unix timestamp.

+ +

The risks of this caching should be carefully considered before enabling it. Using this caching might introduce the following issues:

+ + + + +

The Memcached RDF source

+ +

The Memcached RDF source is similar to the Test RDF source, except instead of using hardcoded data, it reads the test data from a Memcached in-memory database. Note that this does not provide any functionality for caching query results from other RDF sources. In other words, Memcached is not being used for its traditional purpose -- this functionality is only to assist the prototyping of applications when the actual RDF store cannot be accessed.

+ +

To use this functionality, set the aqMemcacheHost and aqMemcachePort global variables in LocalSettings.php to the appropriate values. Create an RDF source with a datastore type of "Memcached", and the appropriate wiki namespace ID, wiki namespace, and datastore URI prefix. The data in the Memcached datatore must be encoded in N-Triples format and keyed by URI (with one entity per cache entry).

+ +

Be warned that enabling the Memcached data source will also enable the Blackbook Cache described above, because the same parameters will be used to enable both.

The Aqueduct API

+ +

When the Aqueduct extension is installed, a Mediawiki API is installed along with it. This Mediawiki API allows external data consumers to query any semantic data that is accessible through the wiki.

+ +

Instead of directly working with RDF sources, the API acts as a "lens" that maps multiple RDF sources into a single wiki. Therefore, all queries are performed using wiki page titles (instead of directly providing URIs and datasource names.)

+ +

The API is invoked from the api.php file that is built into Mediawiki with the "aqueduct" API action. The API has one parameter ("subject") which should equal the title of the page that is being queried. The API will retrieve all semantic data associated with that page and return it as a JSON object. The JSON object will be an object with one property. The name of the property will be the title of the page that was queried, and the value will be an RDF-JSON object representing the RDF that was returned. Read the RDF-JSON specification for more details. 

+ +

There is also a "set" operation that allows you to modify individual triples in Blackbook. The "subject" parameter receives the subject of the triple that will be modified. If "subjecttype" is omitted or set to "page", "subject" should be a wiki page title (as above), while if "subjecttype" is set to "uri", the subject should be an RDF URI. Note that even if "subjecttype" is set to "uri", the URI must still correspond to a page in the wiki, so Aqueduct will know which server should store the URI. "predicateURI" is the predicate of the triple. "object" is a URI or a literal. "objecttype" should be the string "literal" or "uri" to represent the type of the object. The set operation will work on the datasource corresponding to the "Datastore Name" of the RDF source. The entire RDF entity will be materialized, all statements with a predicate matching the given predicate will be removed, the triples will be added, and the entity will be committed to Blackbook. Be warned that, depending on your datasource, triples with special reification (such as "role") could lose their reification during the set operation. If you are using these reified properties in your application, thoroughly test all reification scenarios with the set API.

+ +

For the set to work, the datasource must be an assertions datasouce, created as described in the Siphon section below. (The same Blackbook API call is used to persist data here and in Siphon.)

Installing the Aqueduct extension 

+ +

Installing Aqueduct requires Mediawiki 1.14.0 or higher. Semantic Mediawiki is not required.

+ +

1. Install Mediawiki and verify that it works

+ +

2. Due to a Mediawiki bug (at least in 1.15.1), you need to modify a line in the Mediawiki source code. Load /path/to/wiki/includes/api/ApiFormatJson_json.php . On or around line 818, locate the following line:

+
+
if (class_exists('pear')) {
+
+

Change it to:

+
+
if (FALSE) {
+
+ +

Failure to do this will cause extremely slow Mediawiki performance or timeouts when using the widgets or making API calls. 

+ +

3. Place the AqueductExtension folder in the extensions folder of your Mediawiki installation -- for example, /var/www/wiki/extensions/AqueductExtension. Note that the default location relative to Mediawiki must be used -- a directory called "extensions" must be in your mediawiki directory, and the AqueductExtension directory must be inside "extensions".

+ +

4. Enable the extension by placing the following line at the bottom of your LocalSettings.php file: require_once( 'extensions/AqueductExtension/AqueductExtension.php' );

+ +

5. There is a file called AqueductSQLTbl.sql in the AqueductExtension directory. Run this file against your wiki's MySQL database to generate the database tables.
+ 

+ +

Aqueduct is now ready to configure. At this point, your wiki should be functional with no errors or unexpected behavior.

+ +

Troubleshooting

+ +

Misconfigurations can result in Aqueduct crashing and "Segmentation fault" appearing in your apache log file. Widgets failing with "Error 200" are another symptom of this problem. ("Error 200" often means that Apache crashed while performing the query, and the Segmentation Fault can be seen in the Apache log file.)

+ +

If you are seeing segmentation faults, try the following troubleshooting steps: 

+
    +
  1. Ensure that you are using the latest version of PHP. If you are using Aqueduct with Blackbook, ensure that you are using the latest version of Java. If you compile PHP yourself or supply your own OpenSSL library, ensure that the latest version of OpenSSL is being used as well. Aqueduct has been tested with Java 1.6.0_16, PHP 5.2.6, and OpenSSL 0.9.8g.
    2. +
  2. Ensure that apache is using the "prefork" MPM and not one of the threaded MPMs. PHP is not thread-safe and should not be used with a threaded MPM.

Assumptions

+ +

This document assumes that the reader has a basic knowledge of RDF. The reader should have a thorough understanding of URIs and how they can represent real-world entities. The reader should also understand how RDF statements can represent knowledge about real-world entities through their predicates and objects.

+ +

The reader should also be familiar with Mediawiki administration, including the installation of extensions and the concept of Mediawiki namespaces.

Aqueduct

+

Aqueduct is a collection of software packages to facilitate the rapid development of applications using semantic web technology. Aqueduct provides a set of "building blocks" for creating applications where users can visualize, create, search, and mine semantic data, using open standards such as RDF.

+ +

Aqueduct is currently composed of several software packages:

+ +

Aqueduct extension for Mediawiki: The Aqueduct extension for Mediawiki that provides several services that allow external semantic data sources (such as Blackbook) to be integrated with a wiki. The Aqueduct plugin is distinct from Semantic Mediawiki (another third-party Mediawiki extension.)

+ +

Aqueduct API for Mediawiki: The Aqueduct API allows external programs to read and write semantic data from multiple sources in a machine-readable format by using the wiki as a "hub" or "router" for the data. This allows for the construction of a software system that leverages a wiki in conjunction with other tools or agents, without ending up with multiple inconsistent views of the data.

+ +

Aqueduct (Cistern) widgets for Mediawiki: The Cistern widgets allow for semantic data to be visualized from within wiki pages. Wiki pages with Cistern widgets serve a dual purpose -- they act as traditional wiki pages while simultaneously displaying "widget" controls that allow the user to browse semantic data that is related to the page that they are on.

+ +

Siphon: The Siphon allows for data authored in Semantic Mediawiki to be mirrored in Blackbook. This facilitates the creation of systems that combine the semantic authorship capabilities of Semantic Mediawiki with the data integration and analysis capabilities of Blackbook.

+ +

The Aqueduct documentation contains the following pages:

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Siphon

+ +

Siphon is a software package that mirrors the semantic data in a Semantic Mediawiki wiki into one or more Blackbook datasources.

+ +

Siphon is composed of two components -- the intake extension and the Blackbook feeder. The intake extension captures data from Semantic Mediawiki and outputs it to a queue folder. The Blackbook feeder process reads files from the queue folder and sends the data to Blackbook.

+ +

Setting up the queue folder

+ +

The siphon intake extension communicates with the Blackbook feeder through a queue folder where RDF files are placed. The queue folder must be local to the machine where the intake extension and the Blackbook feeder process are running (not on an NFS volume). This means that the Blackbook feeder process and the queue folder must be located on the same machine where the wiki is. (However, Blackbook itself can be running on a different machine.)

+ +

To set up the queue folder, create a directory that can be read and written by both the Apache process (for Mediawiki) and the Blackbook feeder process.

+ +

Setting up the intake extension

+ +
    +
  1. Copy the SiphonIntakeExtension directory to the "extensions" folder of your Mediawiki installation.
    2. +
  2. Make sure that Semantic Mediawiki is installed and fully functional
    3. +
  3. Add the following line to LocalSettings.php: $wgAutoloadClasses['SMWSiphonStore'] = "$IP/extensions/SiphonIntakeExtension/SMW_SiphonStore.php";
    4. + +
  4. LocalSettings.php should already have a "enableSemantics" line from the Semantic Mediawiki installation. Ensure that you are passing appropriate parameters to the enableSemantics line so Semantic Mediawiki generates appropriate URIs for your semantic pages. The default settings often result in unexpectedly long and complicated URIs. A line similar to "enableSemantics('url:mywiki:',true);" will cause short URIs such as "url:mywiki:TestPage" to be generated, which may be what you want.
    5. +
  5. Add the following line to LocalSettings.php, substituting the queue folder that you set up: $wgSiphonQueueDirectory = '/var/myqueue';
    6. +
  6. Open the SMW_Settings.php file for your Semantic Mediawiki installation. You should see a line that says $smwgDefaultStore = "SMWSQLStore2"; . Change the "SMWSQLStore2" to "SMWSiphonStore".
    7. +
  7. Ensure that the namespaces that you want to use are in the $smwgNamespacesWithSemanticLinks array in SMW_Settings.php. A common source of problems is forgetting to add a namespace to smwgNamespacesWithSemanticLinks when you create a namespace on the Aqueduct configuration special page and expect Siphon to pick up the semantic data.
    8. +
  8. Ensure that RAP is installed and included. To do this, download RAP to a directory accessible to the wiki and add something similar to the following to LocalSettings.php:
    9. +
+ +
+
define('RDFAPI_INCLUDE_DIR', $IP.'/extensions/rdfapi-php/api/');
+include(RDFAPI_INCLUDE_DIR . "RdfAPI.php");
+require_once(RDFAPI_INCLUDE_DIR . 'util/RdfUtil.php');
+include(RDFAPI_INCLUDE_DIR . PACKAGE_SYNTAX_RDF);
+
+

Now, verify that make changes to semantic pages in the wiki causes files to appear in the queue directory. The files should contain the RDF for the semantic data that you added.

+ +

Setting up Blackbook

+ +

Create / Modify the target Data Source such that the following options are filled out in the Blackbook Metadata Manager under Modify Data Source/ Add Data Source page for the specific data source (refer to latest BB version documentation for in depth instructions of how to complete this stage):

+
    +
  • Max merge docs: 1000 (this is sort of a magical number that you may have to modify but must be larger than Merger Factor)
    • + +
  • Merge factor: 100 (like above this info may be found in Jena documentation or BB2 docs at a later stage)
    • +
  • Type: Assertions
    • +
+ + +

Setting up the Blackbook feeder 

+ +

Put the BBSiphonFeeder folder in the directory of your choosing. Examples are /opt, /usr/local, or the users home directory.

+ +

Ensure that the folder that will contain the rdf data to be ingested into Blackbook has permissions equal to the user that will set up this application.
+ +Run the bbSiphonStartupScript.sh script with the following command line arguments:
+./bbSiphonStartupScript.sh periodicity of execution of application(in seconds), fully qualified absolute filepath to bb2Feeder.php(do not use ~ or the like, not dependable), fully qualified absolute filepath to rdf folder, Blackbook server url, path to BB certificate file, BB Certificate Passphrase, path to User's public key file, fully qualified absolute filepath to rdf backup folder, blackbook version number (2 or 3).

+ +

Note that there are two certificates required to use BB3 -- the BB certificate and the user's public key. The BB certificate should be in PEM format (you can use the same file that you used in Aqueduct for the BB Proxy certificate). The user's public key should be the certificate that you install in your web browser to use Aqueduct, converted to PEM (encoded into ASCII characters), and without the associated private key attached.

+ +

If you are using BB2, the public key file is ignored, and can contain dummy content. 

+ +

One way to generate the public key file is to generate a test .php page that dumps the SERVER variables, and then add this test page to a web server running https. When you send the client certificate from your browser, the public key will show up in the SERVER variables.

+ +

One common source of problems is having the wrong style of line breaks in the public key file. If the file has improper line break characters, Blackbook will fail to set the user, with a generic error message.

+ +

Initializing the semantic data

+ +

At first, any pre-existing semantic data will be missing from the Blackbook datasource. To resolve this, force the wiki to re-process all of the semantic data by going to the Admin Functions for Semantic MediaWiki page and starting the "Data repair and upgrade" function. This will start a Mediawiki job that will dump the semantic contents of the wiki into the queue. To force the process to complete more quickly, run the runJobs.php script from the maintenance folder of the Mediawiki installation.

+ +

Operation of the siphon

+ +

Because semantic data is placed in the queue directory for later consumption, it is okay to use the wiki while Blackbook or the Blackbook feeder is down. RDF files will accumulate in the queue directory, and will be processed when Blackbook comes back up.

+ +

However, the presence of the queue in the Siphon system means that there will be a short lag time between editing the wiki and seeing the changes in Blackbook. Keep this in mind in applications where users or agents will be frequently reading and writing semantic data to the wiki.

+ +

Using multiple queue directories

+ +

To send the data from one wiki to multiple Blackbook installations, use multiple queue directories, with one feeder process per Blackbook installation. Do not point multiple feeder processes at the same queue directory. To specify multiple queue directories in LocalSettings.php, use array() to set the $wgSiphonQueueDirectory variable to an array of queue directories instead of a string.
