DataCite4.0 rights and rightsURI

[cziaarm]

Datacite 4.0 uses an item level rights and rightsURI fields to record license information

EPrints records license info at the document level. The following is proposed to handle the transfer of license data between eprintsug/DataCiteDoi and Datacite.

a) Add Eprint field for rights (namedset, multiple)
b) Add Eprint field for rightsURI (namedset, multiple ?? See i) below)
c) Possibly these two as subs in a compound field...
d) (Re)Use document.license.namedset for license values
e) (In eprint_automatic_fields…) Automatic update of item level fields from document metadata
f) Add content type "license attached" to document.license namedset default values (belongs to recollect eprintsug/recollect#2)
g) Where license is "License doc attached" get URI from sibling document with content type "License Document"
h) Include rights MD in rights and rightsURI fields of DataCiteXML export
i) DataCite4.0 schema states that rightsURI is non-repeatable, so a rule must be applied to automatically select an appropriate URI from item level license data
j) Display item level license MD on abstract (updating $c->{summary_page_metadata} possibly out of plugin scope)

Don't do (d).
CC licences are not transmutable (e.g. cc-by-2 cannot be re-stated as cc-by-3.0).
Use URIs for all license values!

Make sure the field type in EPrints doesn't overwrite a non-existing namedset value with nothing when rendered in the workflow e.g.
defined set values. a, b, c,
EPrint field contains: d.
Metafield input renders: a, b, c.
EPrint is saved.
Value 'd' is lost.
