RDF/XML Source Declaration

摘要: When querying or reasoning on metadata from the semantic web, source of this can be great importance. While SPARQL query language provides a keyword to match patterns against named graphs, RDF data model focuses expressing triples. In many cases it is interesting augment these triples with notion for each triple (or set triples), typically an IRI specifying their real virtual origin. This document proposes RDF/XML syntax extension providing attribute specify in representation.
