more discussion is needed for the organisation of the meta.ref

need the <i>meta.ref.pid</i> branch? which usage does it serve
not covered by more precise types of ids? <br>

of the UCD should be to classify the role, usage of the metadata

meta.ref.pid , we can just infer it is an identifier which is
persistent , but can't decide where and how to resolve it.<span

will resolve them.</p>

in the ucd tree already conveys the idea of a persistent
identifier, I guess, because if it would not be persistent, I
would not cite it in a an archive metadata record.</p>
