access and usage constraints

[pvgenuchten]

in the sample i noticed this section on constraints:

accessconstraints: otherRestrictions

This seems inspired by how things are done in ISO19115, unfortunately ISO also is not quite optimal.

More important then access constraints is under which conditions/license the work can be (re)used (CC0, CC-BY, ...) (legal-usage-constaints?).

otherRestrictions is not a proper value by itself, in iso it is usually combined with a second statement to indicate what the other restrictions are.

<gmd:resourceConstraints>
        <gmd:MD_LegalConstraints>
          <gmd:accessConstraints>
            <gmd:MD_RestrictionCode codeListValue="otherRestrictions"/>
          </gmd:accessConstraints>
          <gmd:otherConstraints>
            <gmx:Anchor xlink:href="http://creativecommons.org/publicdomain/mark/1.0/deed.nl">No limitation</gmx:Anchor>
          </gmd:otherConstraints>
        </gmd:MD_LegalConstraints>
      </gmd:resourceConstraints>

If accessConstraints are enforced, it is interesting to state the reason why public access is limited; INSPIRE suggested this codelist with relevant argumentation
