Hi, We from the DO cluster had another discussion about a terminology issue. ---------------------------------------------------------------------- To reiterate, the issue is what term to apply to two groups of things 1) LCSH, AAT, WordNet and the like. These describe concepts that are used in actual medata. 2) FOAF, FRBR and the like. These describe what concrete metadata must look like; defines classes and properties, the instances of which are actual metadata, and in which concepts defined in 1 are used. ---------------------------------------------------------------------- To resolve this we thought it's useful to define criteria: a) the terminology should fit with our (main) public. This is probably library people, so how well it fits with the SemWeb folks is secondary. b) because especially the word "vocabulary" is confusing, we should either avoid "vocabulary" altogether or prepend it so as to distinguish the two e.g. "value vocabulary" and "metadata vocabulary" c) given that people tend to abbreviate terms when they use them, the prepending approach may create the confusion we're trying to avoid. d) if possible it is advantageous to not refer to how the groups are implemented, i.e. do not refer to RDF, XML or anything else. Definition through mentioning how it is implemented can be distracting. ---------------------------------------------------------------------- I've collected all proposals and added a few more: Suggested terms for group 1: - vocabulary - value vocabulary - SKOS vocabulary - KOS - domain vocabulary - controlled list - code list - "thesauri, glossaries, classification schemes and other vocabularies" Suggested terms for group 2: - RDF vocabulary - properties / property set - Set of property and class terms - metadata vocabulary - data elements - element vocabulary - ontology - conceptual model - metadata element set - metadata model - metadata schema - modelling schema ---------------------------------------------------------------------- Mikael's suggestion of "value vocabulary" and "element vocabulary" is really good, but this does mean we'll have to be very careful in drafting our documents to meet criterium c, but this will not help people outside our documents. We have a chance here to think up something that will have a wider use than our documents. If we ignore criterium d, then choosing "RDF vocabulary" for 2 seems obvious, but violates criterium c. Therefore something like "conceptual model" or "ontology" for group 2 is better. My personal favorites are: 1) value vocabulary - expresses that we're dealing with vocabulary concepts that are _used_ in actual metadata. Violates b/c though. 2) metadata model - expresses that these things determine how actual metadata can look like; more neutral term than "ontology" which library people may interpret as something different than a metamodel. Opinions? If you argue pro/con particular terms it helps if you point out the principles/communities on which that preference is based. Best, Mark.
