Manu --
It seems that your definition of "sub-set" may differ from mine.
To my mind --
- JSON is less restrictive than JSON-LD.
- JSON is more permissive than JSON-LD.
- All JSON-LD is JSON.
- Some JSON is not JSON-LD; is JSON-NLD ("Non-Linked Data").
If this were a Venn Diagram, you'd see two circles, one (JSON-LD)
entirely contained within the other (JSON).
Further --
- JSON allows for IRI-less nodes.
- JSON-LD *SHOULD NOT* allow for IRI-less nodes.
An IRI-less node cannot be usefully referred to over time,
nor across graphs (or JSON or other documents). Such a node's
description cannot be re-retrieved later.
An IRI-bearing node can be usefully referred to over time and
across graphs, and its description can be retrieved time and
time again, potentially growing and/or being refined at each
retrieval (dereference).
Such reference (and dereferenceability) is the most important
aspect of Linked Data (LD) that sets it apart from Non-Linked
Data (NLD)-- i.e., the LINK.
Given all that, I think this follows --
- A JSON-LD document MUST NOT include JSON-NLD.
- A JSON document MAY include JSON-NLD and JSON-LD -- i.e.,
it MAY intermingle Linked Data and Non-Linked Data.
- Intermingled JSON-LD and JSON-NLD is preferred over pure
JSON-NLD. Pure JSON-LD is preferred over such intermingling.
Be seeing you,
Ted
