RE: Schema definition for a DID Document?

So as not to surprise anyone…where I’m headed with this is…

Now that I have an operational parser based on the master did-uri-spec grammar working, I’m now working on:

  1.  Designing and implementing a semantic analyzer / VDR access optimizer per the attached seminal System R paper on query optimization  by Selinger et al.

  2.  The backend “VDR” I’m going to test the optimizer with is a set of SQL Server tables (yes SQL tables) created using the following technique for serializing JSON documents:
https://www.red-gate.com/simple-talk/sql/t-sql-programming/importing-json-collections-sql-server/


The goal is to develop the highest performant, cross-VDR DID Processor on the planet.

Ah, right, so, those are JSON-LD @context definitions to go along with the data model. Slightly different purpose than what a schema would be.

I found what appears to be 2 descriptions/definitions here:

Does anyone know their background?  They seem quite different from one another (e.g. wrt service endpoints, etc.)

Thank you Dmitri.

Does anyone have a roughed-out example of what the DID Document schema would look like?

Michael,

We don't have an explicit schema yet, but there's an issue open to add one, on the Implementation guide: https://github.com/w3c/vc-imp-guide/issues/1

A meta description/definition outlining the overall structure of a DID Document, the mandatory elements, provisions for optional elements, ...that sort of thing.

Effectively, the spec text for a DID Document from the DID Spec (https://w3c-ccg.github.io/did-spec/#did-documents) expressing in some sort of schema definition language (e.g. JSON schema?)

Define "schema" -- we have at least 3 working definitions for that term in this group. :)
