Hello everyone,

We are happy to announce the immediate availability of the first stable release of the new Semantic MediaWiki 2.0.x release series.

Semantic MediaWiki 2.0 is a big release that adds several new features, many enhancements, and addresses numerous issues.

    1. Compatibility changes ##

Semantic MediaWiki 2.0 is compatible with MediaWiki 1.19 up to MediaWiki 1.23, and possibly later versions. Support for both MediaWiki 1.23 and MediaWiki 1.24 was improved compared to SMW 1.9. PHP compatibility remains the same as in SMW 1.9: all versions from PHP 5.3.2 to PHP 5.6.x. For a full overview, see our compatibility matrix [0].

    1. Quality and stability improvements ##

A great deal of effort has been put into ensuring both existing and new features work well. Not just at present, but also in future releases. And not just with MySQL and one version of MediaWiki, but on all platforms we support. This dedication to quality has resulted in many bugs being discovered and fixed, and makes future regressions much less likely.

Continuous integration is now an integral part of the development process behind SMW. As of the 2.0 release, SMW has over 2300 automated tests, which cover two thirds of the codebase. These tests are run automatically for every change made to the code, on machines with different databases, different versions of PHP, different SPARQL stores and different versions of MediaWiki.

    1. Semantic Versioning ##

As of the 2.0 release, Semantic MediaWiki adheres to the Semantic Versioning standard [1]. This makes our version numbers more meaningful and makes it easier for administrators to determine if a new release is relevant to them.

    1. Improved SPARQLStore support ##

Semantic MediaWiki 1.6 introduced support for data synchronization with RDF back-ends. SMW 2.0 makes this functionality a first class citizen through many enhancements and stability improvements.

  • New and full support for Jena Fuseki 1.0
  • Enhanced and full support for Virtuoso 6.1
  • Enhanced support for 4store 1.1
    1. Improved subobject support ##

Support for subobjects has been added to the RDF export. This new capability is used by the RDF store functionality to also synchronize subobjects. (#344)

Subobjects now support sorting via the `@sortkey` annotation that stores an individual sortkey per subobject. (#225)

`Special:WantedProperties` for unknown predefined properties

`SMWExporter::findDataItemForExpElement` to enable `SPARQLStore` result display

  • #387 Fixed `SPARQLStore` namespace query support (e.g `
