The W3C Working Group has published a new working draft of Protocol for Web Description Resources (POWDER): Grouping of Resources. "The Protocol for Web Description Resources (POWDER) facilitates the publication of descriptions of multiple resources such as all those available from a Web site. This document describes how sets of resources may be defined, either for use in Description Resources or in other contexts. An OWL Class is to be interpreted as the Resource Set with its predicates and objects either defining the characteristics that elements of the set share, or directly listing its elements. Resources that are directly identified or that can be interpreted as being elements of the set can then be used as the subject of further RDF triples."
