this generally makes good sense to me, although I'm still a little bit confused because in some instances rightsOf is said to point to a CreativeWork and in others it still says that it points to a URI of a Copyright object. Wouldn't Copyright objects no longer exist if that schema is removed from the spec?

I think an example of what what a rightsOf property could point to would help clarify here. For example in the case of Ujo we are issuing Right objects that reference MusicRecording objects. Would rightOf point to the MusicRecording object in JSON format, or a legal document that is hashes and stored on chain? At the moment in our implementation we are not populating this field due to this uncertainty. We are hoping to migrate the data to be inline with the spec though.

Another potentially related question here is how Rights are expected to be referenced from a CreativeWork. In other words, if I have a CreativeWork object, should it contain an array of Right objects? In our case this is how we handle it in order to reference percentageShares on a MusicRecording and then split payments that are made on chain. This seems like a common usecase for these Right objects, but the way we are handling it currently seems potentially out of line with this spec.

In this PR I'm proposing to not completely the concept of Copyright but to make it part of the Right entity by introducing a rightType: Copyright, like proposed in the RRM.

rightOf would always point to the MusicRecording object in JSON format. We have the property license in Right that points to the legal document.

@vrde and I stumped upon the same issue when we did some work for the OMI: #24 I'm afraid we currently don't have a good answer in the specification for this problem. Additionally, it's specific to the blockchain or DLT you're saving the Right onto. IPFS e.g. is not searchable, so backward pointing links are required. Other solutions might one day be available where searching is possible. Until then, we need a makeshift solution. @alexanderattar would you mind adding this use case somewhere in this repo as an issue?

Aha..okay yeah that makes sense. I'm happy to open a separate issue for this
