Hi All (cross-posting from data protocols
Most activity on Data Protocols proposals takes place in the issue tracker
so I thought it would be worth sharing some updates here.
*## Primary Key Support in JSON Table Schema and Simple Data Format*
We're closing in on final agreement on a spec for adding "primary keys" to
JSON Table Schema. Consensus is now away from a simple inline "primarykey:
true" attribute on fields and towards having primary keys along with
"foreign keys" in a separate constraints or keys section. Discussion is in
*## "Foreign Keys" in JSON Table Schema*
Like with primary keys we're look to be closing out foreign keys. Basic
"reference" structure will look like:
"name": # optional name for this foreign key
"fields": string or array of fields on local resource
foreign-key reference as above
More discussion in https://github.com/dataprotocols/dataprotocols/issues/23
*## JSON Data Views Spec Discussion*
Early stage proposal for a JSON spec for describing views of data like
graphs or maps. Probably focus this just on graphs to start with.
