JSON RDF Task Force
The JSON RDF Task Force is primarily responsible for creating a JSON serialization of RDF.
- JSON User Segments - The segments of the Web developer community that are being addressed via this work.
- Use cases - A set of use cases that the group would like to support.
- JSON Design Requirements - A list of questions on particular design questions that are being considered.
- Semantics of JSON - Assumptions about the definition of JSON being used by this Working Group.
- JSON Serialization Examples - Examples of marking up content in each serialization language.
- JSON Syntax Options - A discussion of the various syntax options of the serializations introduced so far.
- RDF JSON, by Talis.
- JSON-LD, by Manu Sporny.
- JRON by Sandro Hawke.
- JSON serialization in the Linked Data API.
- SPARQL Query Results in JSON by DAWG.
- JSN3 by Nathan.
- Flat triples approach to RDF graphs in JSON by Dominik Tomaszuk
- Ideas and issues from the community from RDF Core Work Items build on RDF/NextStepWorkshop, are reproduced below.
- JTriples by Michael Hausenblas
- RDFj by Mark Birbeck
Materials from RDF Next Step WorkShop
- Multiple JSON formats and implementations (some interoperable) already exist showing interest in this work
- Current JSON formats are not aligned - differnent approaches - making it JSON-user friendly versus making it familiar to existing RDF users.
- Needs some R&D and alignment.
- Risk that the result would be some standard that would not be adopted if it was not 'web author' friendly.
- JSON Serialization of RDF
Questions to Contemplate
- What are the use cases for the JSON serialization?
- Are we to create a lightweight JSON based RDF interchange format optimized for machines and speed, or an easy to work with JSON view of RDF optimized for humans (developers)?
- Is it necessary for developers to know RDF in order to use the simplest form of the RDF-in-JSON serialization?
- Should we attempt to support more than just RDF? Key-value pairs as well? Literals as subjects?
- Must all major RDF concepts be expressible via the RDF in JSON syntax?
- Should we go more for human-readability, or terse/compact/machine-friendly formats? What is the correct balance?
- Should there be a migration story for the JSON that is already used heavily on the Web? For example, in REST-based services?
- Should processing be a single-pass or multi-pass process? Should we support SAX-like streaming?
- Should there be support for disjoint graphs?
- Should we consider how the structure may be digitally signed?
- How should normalization occur?
- Should graph literals be supported?
- Should named graphs be supported?
- Should automatic typing be supported?
- Should type coercion be supported?
- Should there be an API defined in order to easily map RDF-in-JSON to/from language-native formats?
