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
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

distinguish "parts of speech?" "JohnsonPhotometry" really represents
some kind of phrase - an enumerated adjective "Johnson" plus a noun,
PPS - one really has to believe that other communities can provide
