Dear all, as you may have seen, the W3C JSON-LD Working Group has recently published a Candidate Recommendation for JSON-LD 1.1[1]. As part of the work on the new specification, the Working Group has defined some new terms that have been added to the core RDF Namespace[2]. These changes are: - A new datatype, called rdf:JSON, similar to rdf:HTML or rdf:XMLLiteral: a literal in JSON syntax[3] - A new class (rdf:CompoundLiteral) and two properties (rdf:language and rdf:direction), all related to internationalization issues, namely the problem of adding base direction to a language literal[4] The goal of the first item is probably clear. As for the second, see more background in [5][6] with a large number of further links. For completeness, I have added the output of a 'diff' to the mail (see below) that shows the changes on the Turtle file. Note that the vocabulary[3] is available in Turtle, JSON-LD, and RDF/XML with the {.ttl,.jsonld,.rdf} suffixes in the URL.
