Ole Olesen-Bagneux: enterprise metadata and the Meta Grid Ole Olesen-Bagneux's Meta Grid is a system for understanding and sharing information about an enterprise's metadata.

RDF Surfaces Primer

RDF Surfaces is a new realization of an old idea by Pat Hayes, to make the logic in RDF portable. It uses Surfaces (positive, negative, neutral, and query) and Graffiti (blank nodes on surfaces) to represent portable first-order logic in RDF.
Excellent work by P. Hochstenbach et al.
