Hiya - I guess I can repeat a post from the civicspace-dev list here to describe the idea of SIOC. It'd be great to have your collaboration Sebastien: I met Kieran L. in July, and talked about our SIOC (Semantically-Interconnected Online Communities) project. Basically, what it is is an open specification for describing communities using online discussion forums or blogs, leading to what some may term "distributed conversations". At the moment, online communities are islands that are not interlinked, and the SIOC ontology has been proposed to not only link these communities but to leverage data in ways that were previously unknown. The initial version of our SIOC specification has been drafted. It can be used in on its own (having a complete set of terms) or in conjunction with other RDF formats such as RSS 1.0 (and 1.1). In terms of producing metadata, we've started with SIOC exporters for open-source discussion systems such as WordPress and Drupal / CivicSpace, and more are on the way. There are obvious connections between SIOC and the subscribe / publish module, so I've asked John van Dyk about this. More info is available from: http://rdfs.org/sioc/ and the Drupal module is at: http://rdfs.org/sioc/drupal/ or in the Drupal CVS contributions area under SIOC. While there are many (useful) classes and properties in SIOC, it can essentially be boiled down to: Users create Posts that are contained in Forums that are hosted on Sites, e.g. Site -> host_of -> Forum -> container_of -> Post -> has_creator -> User Posts have reply Posts, and Forums can be parents of other Forums. Looking forward to your feedback, and of course contributions to the code :-) Thanks, John. -- Kieran Lal wrote:

There are (at least) two modules you'll want to look at. One is CCK

and another is hier

http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/vauxia/hier/ <http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/vauxia/hier/>

which comes out of vauxia's experience with Operon

OK. Thank you very much for your quick answer. What I see from your links is that : - Those modules seem to be far from being released - None of them explicitly deals with RDF

For the second point, is it that RDF approach has been tried but proved to be a dead-end ? Or is it just that it's not been tried ? Because standard-based approach is really a key *feature* for us : we want to be able to use all the tools that deal with with standard RDF.
