Schema Scope

[SmithSamuelM]

Discussion 2021-06-07

One schema (self referential) for the complete VC or Two schema One for the payload included and a non included schema for the Meta Data of the VC (everything but the payload)

Issues:
If rules block is metadata then does the schema block include it or is it in the meta data schema which requires another schema

If schema no explicit then must be fixed which may be problematic if special cases want to add custom vendor specification fields

if schema not specific to payload than data can't live outside VC which defeats some use cases

Solution:

Nester schema where nested schema blocks have own SAI for that nested block. This allows one to extract the nested schema block for the data payload while still have one schema for the whole VC

Nested Schema:

Main Schema
metadata
rules block
data block

Vendor Specific Metadata
issuerid is the block field name for Vendor actually Issuer specific meta data block
