feature request #5606
Add preferred stable URI to SpecimenOrObservation
This URI field should hold only Identifiers using URI syntax, which are presumable stable over time and which are the preferred identifier of the collection/institution owning/managing the specimen.
An example for such a URI are the URI published according to the CETAF recommendations (http://wiki.pro-ibiosphere.eu/wiki/Best_practices_for_stable_URIs).
A test tool for quality testing of such URIs exists at http://herbal.rbge.info/
