It comes down to how the terms are likely to be used - a vocabulary doesn't stand alone, but is embedded in a language which has rules other than idiom, and in a culture that has explicit and implicit usage patterns.
Before we start building a hierarchy of vocabularies, we should assemble usage scenarios. I suggest VOEvent is a good place to start.
The usage above is likely to be something like PhotometricSystem = "Johnson", Bandpass = "R", Value = "22.7 mag", etc. Implicit is that this is some kind of calibrated instrumental value.
PS - we're starting to head right back toward UCDs. On the other hand, our focus shouldn't be on a lot of proper nouns. Should we distinguish "parts of speech?" "JohnsonPhotometry" really represents some kind of phrase - an enumerated adjective "Johnson" plus a noun, "PhotometricSystem".
PPS - one really has to believe that other communities can provide insight. If "ontology" is the answer, what is the question? Received on 2008-02-04Z19:25:54
