JSON-LD (Semantic Uplift)

Building Blocks defining JSON schemas can be annotated with JSON-LD contexts using either:

including a file (context.jsonld) in the building block directory
using the property x-jsonld-context in the _schema.(yaml/json) for the building block - e.g. x-jsonld-context: ../../../sosa-ssn.jsonld

The JSON LD context:

Maps JSON elements to URIs (which can be URIs of a richer semantic model)
Allows validation of complex logical constraints using SHACL Rules to validate examples
Perform transforms to any other RDF model and validate results

Modularity support

JSON-LD contexts are very complex and hard to debug if the schema is at all complex.

The Building Blocks design allows automatic combination of contexts based on the schema re-use patterns.

Context design

_TBD: document local contexts and use of @base mappings. _
