feat: introduce an agreement timestamp #82

Closed jimmarino closed 1 year ago

jimmarino commented 1 year ago

We need a way to anchor contract signing to a timestamp. This PR introduces a timestamp property for contract agreement messages. Extensible ODRL constraints can then reference the timestamp property to demarcate usage periods.

See, for example, https://github.com/Metaform/cx-recommendations/blob/main/doc/contract-in-force-policy/contract.in.force.policy.md

@jimmarino please note that I added a PropertyShape to the contract-agreement-message-shape.ttl file.

ah, and I just forgot that typed literals look a bit different in JSON-LD than one expects in JSON. So please also check my commits in the example and JSON schema file.
