id without url?

[Rafnuss]

In the mindset of maximizing compatibility with datacite, identifier from datacite metadata schema specify that the format should be 10.21384/foo (as opposed as the full DOI url).

Would it make sense to also make this the recomendation for id?

The difference is that DataCite can indicate the identityType, while Data Package cannot:

<identifier identifierType="DOI">10.21384/foo</identifier>

Vs:

"id": "10.21384/foo"

So parsers of DataCite metadata know that the identifier is a DOI, while Data Package parsers don’t (and guessing is tricky). I therefore prefer the full resolved DOI, which is also the recommended format by CrossRef:

"id": "https://doi.org/10.21384/foo"

Now parsers can recognize this as a doi (and URl) and conversion to and from DataCite is easy.

Make sense. Maybe good to specify the DOI URL format in the documentattion?

[peterdesmet]

Good idea. Care to make a pull request?

Made a quick one, but not really good at phrasing such thing consisely. Happy to be reviewed.
