Re: [Social-discuss] The Case for Branching Elgg?

[László Török]

I've only skimmed Elgg and as Melvin notes, it's design is not exactly state-of-the-art, but it works today, so it might be an option to customize it and stick with it for a while.

We could continuously replace parts we don't like.

All in all, I'm delighted to see other advocates of semantic web technologies like RDF and SPARQL on this list.

Thanks,

that would be the quick way, and we could have a pretty decent export for most of the objects (views for raw RDF, RDFa embedded on templates...). We could agree on the ontologies for objects / actions beforehand.

having a closer look at ARC2, it could be an option to tweak the entities system
that elgg uses so it can be exposed (and updated) using SPARQL. The API on the
surface could remain the same, so we can keep using nice plugins :)

Thoughts?
