[Suggestion] Make ORCID a valid user.domain in make_eml() arguments

[earnaud]

The title says it all, here is the detail: for the user.domain argument of the make_eml() documentation, some metadata repositories are listed. But since the goal is to identify the way a user is known and as ORCID is widely used for authentication goals, shouldn't it be also a valid user.domain ?

I think we can do this @earnaud. How do you want this information rendered in the EML?

<access authSystem="https://orcid.org/" order="allowFirst" scope="document" system="https://somesystem.org">
    <allow>
      <principal>XXXX-XXXX-XXXX-XXXX</principal>
      <permission>all</permission>
    </allow>
</access>

[earnaud]

I was thinking about ORCID's integration in metacat: maybe the authSystem shall be the base URL of the metacat in which it would be uploaded eventually (which could be checked by a curl request).

Or maybe did I miss something about the meaning of authSystem ...

Concerning the rest of the content you present, it seems to be ok.

Do you have an example of what metacat expects for the access node?
