JSON-LD Algorithms and API 1.0: 2nd Last Call

The JSON-LD Community Group and the RDF Working Group have announced the 2nd Last Call publication of the JSON-LD 1.0: Algorithms and API specification.

JSON-LD harmonizes the representation of Linked Data in JSON by describing a common JSON representation format for expressing directed graphs; mixing both Linked Data and non-Linked Data in a single document. The format has already been adopted by large companies such as Google in their Gmail product and is available to over 425 million customers around the world.

The syntax is designed to not disturb already deployed systems running on JSON, but provide a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Linked Data Web services, and to store Linked Data in JSON-based storage engines. The JSON-LD 1.0 Algorithms and API specification describes useful Algorithms for working with JSON-LD data. It also specifies an Application Programming Interface that can be used to transform JSON-LD documents in order to make them easier to work with in programming environments like JavaScript, Python, and Ruby.

This is a 2nd Last Call publication for the JSON-LD 1.0 Algorithms and API specification. Changes since the previous publication include a shift to use a Future's based API design approach, better base URL processing, and better translation of data from RDF. All substantive technical work on the specification is complete. Feedback on both specifications is encouraged and should be sent to public-rdf-comments@w3.org. The 2nd Last Call period will end in 3 weeks, on June 06th 2013.
