as far I saw only XSLT-template, I thought it's the FOAF.Vix itself.
I'm working on project that stores data in RDF with FOAF-shema for
user profiles. Right now we are rendering profiles to HTML using basic
template system, and it works well for us. I've just got some ideas
that XSLT-rendering could be useful for public FOAF export, but I'm
not sure that it would be possible to use FOAF.Vix without
modifications.
We are developing on Python with Redland as storage. Hope, I will
release some our Python&RDF snippets too.
