Appendix A — JSON Schema

Contents of DID 0.1

The normative JSON Schema is published as did.schema.json (JSON Schema draft 2020-12), $id https://etalii.net/adp/did/schema/0.1/did.schema.json. Its root, #/$defs/Definition, validates definitions, and every definition example validates against it.

`$defs`	Validates
`Definition`	A stored diagram (section 3).
`ElementRecord`	An element record.
`RelationRecord`	A relation record.
`ViewRecord`	A view record.
`NodeView`	The view data of a node.
`EdgeView`	The view data of an edge.

QualifiedId, SemVer and Point are referenced from https://etalii.net/adp/disl/schema/0.1/disl.schema.json. As in DISL, all objects forbid unknown properties except extension properties matching ^x-. Rules that JSON Schema cannot express — conformance to the specification's metamodel, id uniqueness and resolvable references — are the job of a DID validator that has the specification loaded.
