Yeah. I'd just say that we don't support Windows. I can't imagine
getting 4store to build on Windows without a lot of work :P

In principle I think you're right -- it should be an independent
library. Only at the moment there are only 2.5 projects that are using
it (bibliographica, semantic.ckan and maybe wdmmg). wdmmg is likely to
stress it more...

So I agree, a big caveat to anyone trying to use rdflib as a back-end
for anything serious, highly recommend using 4store. I don't think the
4store problems are particularly show-stopping. Most of the issues that
people seem to have are bad/old versions of the dependencies and/or
version skew -- 4store built from one source tree and py4s from another.

Hopefully in the fullness of time rdflib will get better and the
distribution/packaging of 4store will get better. At which time we will
be ready!


Cheers,
