For reaching the desired confidence on topological and linguistic properties found on social systems, I decided to publish a collection of linked open social data from Facebook, Twitter, LinkedIn, IRC, GMANE email lists, Participabr, Cidade Democrática and AA.

All data are in currently not in a SparQL endpoint, but available as plain RDF text in git repositories. Routines for the translation of raw and relational data into linked data (RDF) are in repos of my github account, specially in the percolation, social, gmane, participation and music python packages.
