Collaborative Spaces, SWCS 2013, held in Montpellier, France, in May 2013, and
the Third International Workshop on Semantic Web Collaborative Spaces, SWCS

sections on challenges in collaborative spaces, modeling collaborative
communities and the role of semantics, semantic MediaWiki communities, and
exploiting semantics in collaborative spaces.
