At the point I felt it was approximately functionally complete, I made
the leap from developing on Jena to developing in Sesame. I don't know
how to quantify the differences in features now, but the branch occurred
in August, and I've made bugfixes and added features (like FSL support)
in Sesame that weren't rolled back into the Jena version, which I no
longer support.

I think almost any development you do at this point would be valuable.
If you can improve on existing codebases, that would be great; if they
aren't re-usable enough, that would also be extremely useful to know.

Indeed. Thanks for joining in.
