Following the newly minted “recommendation” status of RDF 1.1, Michael C. Daconta of GCN has asked, “What does this mean for open data and government transparency?” Daconta writes, “First, it is important to highlight the JSON-LD serialization format. JSON is a very simple and popular data format, especially in modern Web applications. Furthermore, JSON is a concise format (much more so than XML) that is well-suited to represent the RDF data model. An example of this is Google adopting JSON-LD for marking up data in Gmail, Search and Google Now. Second, like the rebranding of RDF to ‘linked data’ in order to capitalize on the popularity of social graphs, RDF is adapting its strong semantics to other communities by separating the model from the syntax. In other words, if the mountain won’t come to Muhammad, then Muhammad must go to the mountain.” Read more

Almost exactly 10 years after the publication of RDF 1.0 (10 Feb 2004, http://www.w3.org/TR/rdf-concepts/), the World Wide Web Consortium (W3C) has announced today that RDF 1.1 has become a “Recommendation.” In fact, the RDF Working Group has published a set of eight Resource Description Framework (RDF) Recommendations and four Working Group Notes. One of those notes, the RDF 1.1 primer, is a good starting place for those new to the standard.
Lanthaler said of the recommendation, “Semantic Web technologies are often criticized for their complexity–mostly because RDF is being conflated with RDF/XML. Thus, with RDF 1.1 we put a strong focus on simplicity. The new specifications are much more accessible and there’s a clear separation between RDF, the data model, and its serialization formats. Furthermore, the primer provides a great introduction for newcomers. I’m convinced that, along with the standardization of Turtle (and previously JSON-LD), this will mark an important point in the history of the Semantic Web.”
Ivan Herman of the W3C reports, “The W3C RDF Working Group has published two Last Call Working Drafts: (1) A Last Call Working Draft of RDF 1.1 Concepts and Abstract Syntax. The Resource Description Framework (RDF) is a framework for representing information in the Web. Comments are welcome through 6 September. (2) A Last Call Working Draft of RDF 1.1 Semantics. This document describes a precise semantics for the Resource Description Framework 1.1 and RDF Schema. It defines a number of distinct entailment regimes and corresponding patterns of entailment. It is part of a suite of documents which comprise the full specification of RDF 1.1. Comments are welcome through 6 September.” Read more
