Dear Working Group:

I am working on standardization of token implementations on the Ethereum
blockchain and related projects. Our specifications ERC-721 and ERC-1155
depend on JSON-LD, specifically this is how we connect tokens to our data
(like 2018-mazda-with-vin-2938473947937.json) to our schemas (like
cars.json) using the "$schema" link.

Our concern is that simply linking to a document ("$schema": ...) does not
provide integrity. Our workaround is an approach that is similar to the W3C
SRI specification. Our standard draft is at
https://github.com/ethereum/EIPs/pull/2477/files

But we think this approach can be generalized and should be applicable to
other JSON-LD users.

I would like to propose a specification for "$schemaIntegrity",
"@contextIntegrity" and other "@*Integrity" which allows publishers of data
to specify that they are making reference to specific versions of documents.

Would discussion on such a feature be welcome here?
