For example, it is now pretty common to post to Twitter, and this post becomes a post in my wall in Facebook. It would be nice to represent the relation between these two posts. I don't think this can be represented directly using SIOC, for instance. dc:source ? I can't really believe that SIOC does not have this feature. Well, I could not find it, hence my question. Hopefully the SIOC Gurus may have an answer... As Stuart pointed out, we want to capture the fact that it is the same post, but within different contexts. In many cases, they will be generated automatically... As Nathan, suggested, the sioc:sibling has been designed for that http://rdfs.org/sioc/spec/#term_sibling An Item may have a sibling or a twin that exists in a different Container, but the siblings may differ in some small way (for example, language, category, etc.). The sibling of this Item should be self-describing (that is, it should contain all available information). Won't it be enough for your needs ? Best, Alex.

Re: Organization ontology
To give some different perspective, I don't believe that any of those issues w/r/t to other governance models impinge on the quality or utility of this organization ontology whatever. Does it accurately depict every possible scenario? Not at all. Is it adequate for the use cases and requirements it was set out to achieve? It certainly appears that way. Further, governance is -- as Dave points out -- in some ways orthogonal to organizational structure (so, in some sense this is *not* true, in that some org structures prohibit or inhibit some control models, and vice versa, but that only matters here if it does, and I claim that it doesn't). This is -- as I said on Twitter last week -- outstanding work and we will be adopting adapting it in our work at NASA and other fed govt customers.
