'two key' may be close enough to 'three' :) Depending on how you count, there may be many more: literals, datatypes, datatype maps, … So let's count only key data structures. I hope you're not asking me to normatively define graphs and datasets as “key data structures” in the body text ;-) Best, Richard > > On 11/7/2012 9:13 AM, Richard Cyganiak wrote: >> There were some comments about the RDF Concepts abstract not reflecting the content in sufficient detail.

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 comprise a default graph and zero or more named graphs, and are used to to express metadata about RDF graphs, and to organize data by context. This document also introduces key concepts and terminology, and discusses datatyping and the handling of fragment identifiers in IRIs within RDF graphs. >> ]] >> http://dvcs.w3.org/hg/rdf/raw-file/default/rdf-concepts/index.html#abstract >> >> Proposals for further improvement are welcome. >> >> Cheers, >> Richard >> >> > >
