In !SimDB, particularly in its data model, we aim to use pre-defined semantic vocabularies. The idea is that certain "label" attributes in the model should obtain their values form such a vocabulary, to indicate in an agreed upon vocabulary what the meaning is of a certain object. Examples are the "ucd" attribute on !InputParameter, or the "label" attribute on !TargetObject

Some feedback on this idea was provided by Norman Gary (TBD find email link).

To discuss:
   * How about our formalisation of this in UML (stereotype + tag definition (for URI)). (also to DM)
   * How about our idea to restrict values to those in the vocabulary, or should we merely "suggest" its usage?
   * Which vocabularies are appropriate to the particular labels, or do we need to create new ones?
   * Currently in profile the stereotype is named <<ontologyterm>>, though a word in a SKOS vocabulary is intended. Should we rename, or should we keep this name for possible future generalisation?
   * If we stick to SKOS, how should the values actually be provided. As preferedLabel, as URI, as ???
   * Should we support, in the TAP query interface, querying for narrower/broader terms as well? (Could be done by introducing a database model for the vocabularies and their relations ...)
   * ...
