we've recently announced the release of SparqlExtension (http://www.mediawiki.org/wiki/Extension:SparqlExtension) in the -dev mailing list where it generated sufficient interest. Since then we've added a bunch of new features (and bugs).
SparqlExtension is a triple store connector, an alternative to Halo TSC functionality. The good news are: it's open source and it's modular, meaning that it integrates with a bunch of other extensions (such as Maps, Graph, Charts). It also leverages off the existent SMW rdf export functionality.
So far we have only tested it with Joseki/Jena/TDB endpoint but as the connector uses the standard endpoint (RESTful) api and SPARQL /Update there should not be any problem to connect it to any other triple store implementation. Another feature is that it automatically exposes your data to the rest of the world via the same endpoint.
