W3C Names Turtle a Candidate Recommendation

Angela Guess — Wed, 20 Feb 2013 13:00:56 +0000

Ivan Herman of the W3C reports, “The W3C RDF Working Group has published a Candidate Recommendation of Turtle – A Terse RDF Triple Language. This document defines a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the existing N-Triples format as well as the triple pattern syntax of the SPARQL W3C Recommendation.” continued…

New Working Draft of RDF 1.1 Concepts and Abstract Syntax

Angela Guess — Thu, 17 Jan 2013 13:00:38 +0000

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.” continued…

RDF & Dilbert

Angela Guess — Tue, 08 Nov 2011 18:30:15 +0000

A new article by Dan Brickley looks at RDF through the lens of beloved comic strip, Dilbert. The article begins, “How can we package, manage, mix and merge graph datasets that come from different contexts, without getting our data into a terrible mess? During the last W3C RDF Working Group meeting, we were discussing approaches to packaging up ‘graphs’ of data into useful chunks that can be organized and combined. A related question, one always lurking in the background, was also discussed: how do we deal with data that goes out of date?” continued…

RDF Working Group Publishes Draft of RDF 1.1 Concepts & Abstract Syntax

Angela Guess — Thu, 01 Sep 2011 14:30:26 +0000

The W3C reports that “The RDF Working Group has published the First Public Working Draft of RDF 1.1 Concepts and Abstract Syntax. The Resource Description Framework (RDF) is a framework for representing information in the Web. This document defines an abstract syntax (a data model) on which RDF is based, and which serves to link concrete syntaxes to its formal semantics. It also includes discussion of key concepts, datatyping, character normalization and handling of IRIs.” continued…

W3C Publishes First Working Draft of Turtle

Angela Guess — Mon, 15 Aug 2011 09:00:29 +0000

In case you missed it, “The RDF Working Group has published the First Public Working Draft of Turtle (“Terse RDF Triple Language”). Turtle has been in use by the Semantic Web community for a long time; this document is the first formal step to, eventually, turn it into an official W3C Recommendation.”

The Turtle home page elaborates, “Turtle is already a reasonably settled serialization of RDF. continued…
