In a previous blog post I suggested that the emerging SIOC-o-sphere should be described as "Blogosphere 2.0". Well, as I think about this a little deeper, I have come to the realization that this cannot really be correct (even though it may be more buzz worthy etc..). The fact of the matter is that, SIOC is about Semantically-Interlined Online Communities (Data Spaces) comprised of Blogs, Wikis, Discussion Forums etc.. Thus, "Blogosphere 2.0" is simply a part of the SIOC-o-sphere :-) Ditto the Wikisphere and so on...
What is Blogosphere 2.0 anyway?
Blog clusters that incorporate the "Open Data Access" dimension to their usage pattern via content exported as RDF Data Sets or Virtual RDF Data Sets (as demonstrated by the OpenLink Data Spaces SIOC Reference). In either scenario, the RDF rendition of blog content is accessible for to ad-hoc querying via SPARQL (btw - checkout this cool SPARQL FAQ).
The really fascinating thing about the "Blgosophere 2.0" is that the transition from "Blogosphere 1.0" is going to be transparent! The "Open Data Access" will actually do the talking etc..
