Re: Trying to build rdflib on Windows

[Gunnar Aastrand Grimnes]

Iain,

The windows build was always problematic. That's why the C sparql
parser was swapped for a pure python one later.
Unfortunately the pure python parser was never 100% polished, and was
never released. (Question for everyone else, did we make a svn tag for
this state?)

Meanwhile we have moved sparql out of the core, and cleaned it up a
lot. If you checkout svn head you will find a leaner and pure python
rdflib, BUT without sparql support.
This has been moved to the http://code.google.com/p/rdfextras/ project
- although I am unsure how easy it is to integrate it ATM.

Sorry for the messy state of things - we are working hard (i.e.
talking about it a lot) on releasing a 3.0, then starting to clean up
rdfextras.

- Gunnar

Gunnar,

Thanks for your reply. I'll check out the rdfextras as well and have a
play around with that.

No worries about being messy, I realised that things were in a state
of flux.

If I have any queries, I'll come back.
All best,
Iain
