Thread:Semantic-mediawiki.org:Community portal/SMW 1.8.0 Subobject incompatiblity with RDF store

I posted this on the 1.8.0 forum but maybe it will get more traffic here:

Just wondering if the development group is aware of a subobject bug when using RDF as the SMW store. This issue has been reported elsewhere (http://wikimedia.7.x6.nabble.com/RDF-export-of-subobjects-SIO-in-SMW-1-8-broken-td5001638.html). We setup our SMW installation with SQLStore3 with heavy usage of subobjects. All queries work fine with this setup. To gain improved speed, we migrated the SMW data to 4store and although queries of routine properties and categories work, subobject queries are broken as if they do not exist in the system. Any help with this would be appreciated or if it is already being addressed in version 1.9.0, then please let me know.

Thanks,
