Add hashes for context and vocab files. #116

Closed msporny closed 1 year ago

msporny commented 1 year ago

This PR addresses issue #115 by normatively referring to the appropriate JSON-LD Context files and vocabulary documents. This is similar to the language in the VC v2.0 specification:

https://w3c.github.io/vc-data-model/#base-context

... but follows @jyasskin's suggestion on treating values as already dereferenced. Where it makes sense, cryptographic hashes are provided and implementers are instructed to NOT load the documents from the Web, but rather treat them as already dereferenced with the contents of the files identified by cryptographic hash.

@iherman, pay particular attention to the cryptographic hash value for the machine-readable vocabulary and the normative statement related to it. If you are ok with that approach here, I can do something similar for the VC v2.0 specification.
