Making RDF Data Available for XML processing "The RDF Data Access Working Group is charged with providing access to RDF Knowledge Bases (repositories, data stores – we will use the term repository) by selecting instances of subgraphs from an RDF graph. This will involve a language for the query, and the use of RDF in some serializations for the returned results. As part of the requirements process, the Working Group has refined this to include Variable Binding Results and local access to RDF repositories."
Defining N-ary Relations on the Semantic Web: Use With Individuals "In Semantic Web languages, such as RDF and OWL, a property is a binary relation: it links two individuals or an individual and a value. How do we represent relations among more than two individuals? How do we represent properties of a relation, such as our certainty about it, severity or strength of a relation, relevance of a relation, and so on?"
