Right, I will probably just release the sesame4 as a private one-off on
GitHub, I think it would only be useful to a narrow set of users who are
"temporarily stuck" with sesame (as I am in one project I don't want to
maintain too much) but want to wriggle their way over to RDF4j via Commons
RDF, say one class/module at the time.

Thankfully rdf4j and sesame live well on the class path together! (But I
guess that could break if RDF 4J moves on to way newer dependencies)

Yes, that could be a possibility, but I think Commons is still not quite
ready for "micro" git repositories as it would complicate web site
maintenance and release processes. it's easy enough to split out the
modules with git subtree, but not if you keep developing on both sides
afterwards. :)

Yes, I think that would be good goal, so perhaps the JSONLD-Java model
would work here as well, then it does not matter so much "how integrated"
Commons RDF gets where - Commons could still provide an empty "glue" Maven
artifact to depend on such external integrations (or just list them on the

BTW, as I'm currently the sole author of the commonsrdf-rdf4j integration I
could contribute it separately to Eclipse under the EPL, if so desired.
