Add Codemeta terms

[stain]

See namespace considerations in #275 before merging.

Not sure if we should add this for 1.2 when we don't have a corresponding section explaining when to use embargoEndDate etc. Suggest to delay this for 2.0.

@dgarijo to double-check the PIDs

I added a few comments @stain. In Codemeta we resolved the resolution and content negotiation of w3id.org/codemeta, but at this time, the id is still https://codemeta.github.io/terms/. I followed with another comment to see if we can push forward changing the id of the vocabulary. That may lead to incompatibility changes, so I am not sure how reluctant will people be.

I suggest using for now the current Codemeta id, even if it's not machine readable

[stain]

It's OK, better remain compatible for now and use codemeta.github.io namespace.

I can add the machine readable definitions to our core Profile Crate for 1.2-DRAFT, but we would need to add also human-readable text to explain also why these URLs are 404 Not Found.

As shown in codemeta/codemeta#360 my proposal is to move it to https://w3id.org/codemeta/terms/

It would be great if you drop a +1 to show your support to this change

[dgarijo]

Hopefully by June 20th we'll get it solved. But community standards are slow sometimes.

I've added machine readable version in https://github.com/ResearchObject/ro-crate/blob/codemeta/docs/1.2-DRAFT/ro-crate-metadata.json#L736 , which you are free to adapt/correct. Unsure about if domainIncludes should always be SoftwareApplication

Edit: Most of them say SoftwareSourceCode in https://github.com/codemeta/codemeta/blob/master/crosswalk.csv#L63

[dgarijo]

I will review when time allows. Thanks!
