Re: Distributed versioning for RDF?

Yes. I meant (and want) live access, but would never expect an RDF  
schema to provide this. ;-)


Changesets seem very useful for exporting histories.

It's a linked changelog so older versions are reconstructable

Distributed versioning for RDF?

2009-07-29 Thread Axel Rauschmayer
Offhand, I see the following requirements for many (mostly social) RDF 
applications:


- text indexing
- text diff for versioning
- distributed versioning and synchronization. 
http://en.wikipedia.org/wiki/Distributed_version_control

- provenance: author, data source (which might have named graphs)

Open Anzo [1] and OpenLink Data Spaces [2] come pretty close, but, as 
far as I can tell, don't offer distributed versioning.


Is there anything else out there that I might have missed?

Thanks!
