Ivan Herman of the W3C reports, “The W3C RDF Working Group has published a Working Draft of RDF 1.1 Concepts and Abstract Syntax.”

Ivan Herman of the W3C reports, “The W3C RDF Working Group has published a Working Draft of RDF 1.1 Concepts and Abstract Syntax. RDF 1.1 Concepts and Abstract Syntax defines an abstract syntax (a data model) which serves to link all RDF-based languages and specifications. The abstract syntax has two key data structures: RDF graphs are sets of subject-predicate-object triples, where the elements may be IRIs, blank nodes, or datatyped literals. They are used to express descriptions of resources. RDF datasets are used to organize collections of RDF graphs, and comprise a default graph and zero or more named graphs. This document also introduces key concepts and terminology, and discusses datatyping and the handling of fragment identifiers in IRIs within RDF graphs.”

The document states, “This document is a snapshot of the RDF Working Group‘s progress towards updating the RDF data model for RDF 1.1. A list of changes since theprevious working draft is provided as an appendix. The most significant normative change in this Working Draft is the adoption of the concepts ofRDF Dataset and named graph from SPARQL. The introduction has seen major changes, as have various informative notes throughout the document. Various areas of ongoing work are marked throughout the text, in particular the definitions of blank nodesill-typed literalsoperations on RDF datasets, and the relation of RDF datasets to aspects of web architecture.”
