Semantic Bundle

Jump to: navigation, search

Semantic Bundle (abbreviated as SB) is a pre-packaged bundle of extensions for use with wikis that are based around the Semantic MediaWiki extension. It can be obtained either through Git or by downloading a single .tgz or .zip file.

Semantic Bundle is a suitable alternative if you cannot run Composer to install or upgrade SMW (1.9+) and a number of other extensions that require Composer, such as Maps (3.0+). Do not run Composer if you want to install Semantic Bundle.

The composer version of this project is on GitHub.


Semantic Bundle contains a large number of MediaWiki extensions, and several other PHP libraries. Chief among them is of course:

There are also libraries and extensions required by Semantic MediaWiki:

Other SMW-based extensions included in this bundle are:

Finally, there are other extensions included in Semantic Bundle that, though they do not use Semantic MediaWiki directly, are often used in conjunction with SMW. These are:

  • Admin Links - defines a special page that serves as a "control panel" for administrative tasks
  • Approved Revs - allows for setting a single revision of any page as the "approved" one; if the page contains any SMW data, it's the approved revision's version that is stored
  • Arrays - defines useful parser functions for manipulating arrays
  • Data Transfer - allows importing data into and out of the wiki via XML and CSV formats
  • External Data - allows for displaying data from outside APIs in the wiki
  • Header Tabs - allows to convert top-level sections of the page into tabs; often used with Semantic Forms to make long forms more user-friendly
  • Maps - allows for displaying individual points and geocoding addresses using various map services; required by Semantic Maps
  • Page Schemas - lets users define a schema for each category that can be used to automatically generate templates, forms, etc. for that category
  • Replace Text - provides a form for administrators to do a text search-and-replace across the wiki
  • Widgets - allows adding widgets to the wiki by simply creating pages in the "Widget:" namespace

Semantic Bundle is not at all meant to be a comprehensive set of useful extensions, and there are many other extensions that are also quite useful, either in conjunction with SMW or in general, that were not included in the bundle. Most notably, there are various extensions that are bundled into MediaWiki, and thus don't need to be included in SB:

There are many other extensions that weren't included, for technical or other reasons, and we would encourage administrators setting up an SMW-based wiki to look at the wide variety of other extensions available. Some of these other helpful extensions include CategoryTree, Live Translate, Math, OpenID, Push, Semantic Signup, Semantic Tasks and Translate.


Semantic Bundle is available either as a downloadable .zip or .tgz file, or via Git.

Package download[edit]

You can download the current version of Semantic Bundle, corresponding to Semantic MediaWiki 1.9.2, at either of the following URLs:

At either page, select "File > Download" or hit "Ctrl + s" to download the file.

Once you have the .zip or .tgz file, you should move it to the /extensions directory and extract it there. e.g. tar zxf SemanticBundle-20140514.tgz

Until 2014, Semantic Bundle was available at Google Code. Unfortunately, in early 2014 Google Code stopped allowing downloaded files, which is why the location moved. However, old downloads can still be found at that site.

Downloading using Git (experimental)[edit]

WARNING! This is experimental! You must know what you're doing!

From your extensions directory, run:

git clone

The bundle building code will be cloned into extensions/SemanticBundle. Change into this directory and run the following command:


this will create externals in your /extensions folder for all the extensions in the bundle and will automatically run svn update to fetch all the components of the bundle.

To check out development releases (trunks) of all the extensions in the bundle instead, run:

make dev

this will modify the externals and run update again switching over to trunk releases.

Note: if your MediaWiki is not managed using Git, you can get the latest version of Semantic Bundle using the Git command above, then type:

make all

which will build a .tgz file which you can extract in your extensions directory.


Extracting the files will create directories under /extensions for each of the extensions contained in Semantic Bundle.

If you enter the "SemanticBundle" directory, you will see SemanticBundleSettings.sample.php and SemanticBundle.php, among several other files. SemanticBundleSettings.sample.php contains calls to include all the extensions that Semantic Bundle contains. By default, the calls to all extensions but Semantic MediaWiki are commented out. Don't un-comment these until after initializing Semantic MediaWiki; see below.

Copy the existing SemanticBundleSettings.sample.php file to a new file, named SemanticBundleSettings.php. You shouldn't directly use SemanticBundleSettings.sample.php (even though it's possible), because any changes you make to the file SemanticBundleSettings.sample.php will be lost if you ever upgrade to a new version of Semantic Bundle.

Then, include SemanticBundleSettings.php and SemanticBundle.php within LocalSettings.php:

require_once( "$IP/extensions/SemanticBundle/SemanticBundleSettings.php" );
require_once( "$IP/extensions/SemanticBundle/SemanticBundle.php" );

It should be noted that SemanticBundle.php isn't actually required - but it holds version information for Semantic Bundle, which can help with debugging; and it's also good marketing for the Semantic Bundle project - so we ask you to please consider including it.

Initializing Semantic MediaWiki[edit]

The next step is to initialize Semantic MediaWiki. First, make sure that you are logged in as an administrator/sysop, such as the WikiSysop user. Then, go to Special:SMWAdmin, and click on the "Initialize or upgrade tables" button.

After successful initialization, open up SemanticBundleSettings.php and uncomment the extensions you would like to use.

Note: it's strongly recommended to initialize SMW before you include (i.e., uncomment) any of the other SB extensions (other than Validator, which is necessary), to avoid potential errors from extensions that require SMW.

For more information on installing the extensions, see the installation and configuration sections for each extension. Of the extensions currently in SB, Approved Revs and Widgets require some additional setup before they can be used.


Semantic Bundle provides a number of important benefits over downloading and installing individual extensions; among them:

  • it provides a "best practices" set of extensions around Semantic MediaWiki, based on user experiences
  • it simplifies download, especially for those systems that don't have Git, and especially for those extensions (like ParserFunctions) that don't have a standard downloadable version already
  • it tries to guarantee working code by using tagged, stable versions of extensions whenever possible
  • it simplifies installation by providing a pre-generated list of includes

On the other hand, with individually-downloaded extensions, you may stand a better chance of having fully-up-to-date extensions, since the versions in Semantic Bundle are usually but not always the most recent.


Semantic Bundle was initially created by Sergey Chernyshev and Yaron Koren in May 2008. It was later maintained by Yaron Koren and Jeroen De Dauw. It is currently maintained by Yaron Koren.


Semantic Bundle uses the BSD license.

Each extension in the bundle uses its own license, however: please consult extension pages for licensing details.
