Cool! I had a quick look at it. It would be helpful to see a complete example of an application using this package as well :-)
Integrating linked data could be cool, Startin'Blox has a library DjangoLDP which leverages Django as well. In theory client applications would need to invest a little time in providing the semantic mappings to their data. Maybe we could extend the Groundwork datasources to serialize into application/ld+json for example when requested, using DjangoLDP's generic LDPSerializer
