2. JSON-LD 1.1
It’s been over three years since JSON-LD 1.0 was published, and feature requests have been mounting:
36 issues addressed since 1.0 (15 still open)
Use objects to index into collections, rather than only array form
Previously restricted Now available
Can with other container types (e.g.:
Framing, never complete in 1.0. Now provides ability to match inclusive or exclusive @type, property values, and specifics of a value object. Supports framing of datasets, not just graphs.
Contexts scoped to terms: property values or entities using a given type term can overlay terms-specific contexts.
Ignore some elements of JSON structure.
Abstract from JSON-itself, allowing for YAML, CBOR and other LD representations.
