i thing learned object oriented programming last semester. the professor taught us inheritance. you define a class with some properties. the sub classes inherit the properties. they extend the propertie. you do not repeat the properties. you reuse the properties.

that inheritance concept came back to me when. i read how schemas work in Sign Protocol.

schemas in Sign Protocol are composable. a developer can reference existing schemas as components in a new schema. a national ID schema already exists in the registry. a benefits eligibility schema can reference the ID schema for the identity fields rather than redefining them. the eligibility schema extends the ID schema with additional fields specific to the program. any attestation conforming to the eligibility schema also implicitly carries the identity verification from the base schema.

composable schemas means that the registry becomes more and more powerful as more and more schemas are added. it doesn't start from scratch with each new schema but rather adds to what already exists.

what schema combination you think would produce the most useful composite attestation for practical use ? tell me in comments.
