That's great! Would the commons-rdf dependency go in jena-core/pom.xml? Is it going to be necessary to change some classes in the core? I think it will be transparent for other modules like ARQ, Fuseki, Text. Is that right? > There is a lot more to working with RDF than the RDF API part - SPARQL > engines don't use that API if they want performance and/or scale.

Good point. I'm enjoying learning about Jena code for JENA-632. Even though datasets, streaming queries collections and all that part about journaling and graph persistence can be a bit scary. Probably that won't be covered in the commons-rdf, but I think that's correct. Thanks!
