[tdwg-content] DwC for the semantic web

This is a good point and one with which I generally agree. In this
particular case, the term IndividualOrganism has its roots in the
discussion of last October/November. At that time, I had proposed
adding a class to Darwin Core called dwc:Individual which would be the
object of the existing term dwc:individualID. In that discussion, there
were various options that were thrown around for the class name but in
the end, it was left as Individual to correspond with the individualID
term (in the same way that dwc:occurrenceID goes with dwc:Occurrence,
dwc:eventID goes with dwc:Event, etc.). Since Cam and my intention was
for the class dsw:IndividualOrganism to mean the same thing as I had
originally wanted the proposed dwc:Individual class to mean, we stuck
with the "Individual" part even though the definition always allowed for
small groups of organisms (see the definition of dwc:individualID at
http://rs.tdwg.org/dwc/terms/index.htm#individualID). However, since
DSW is designed for the semantic web/LOD world and since "individual"
has a different technical meaning in that context, we thought
"IndividualOrganism" was more clear than just "Individual" (I think Pete
DeVries first suggested IndividualOrganism somewhere in the
discussion). Whether or not that was the best choice or not, I don't
know. Often "IndividualOrganism" actually does correspond to an
individual organism, so calling it that does allow for a certain amount
of visualization of what it represents, although as the discussion of
Oct/Nov showed, there may be problems associated with trying to put too
much concrete meaning on something that is essentially abstract.
By the way, as far as I know the proposal for the dwc:Individual class
is still on the table since as far as I know the TAG has taken no action
to submit it to an up or down vote. Given that, I suppose there is
still some rationale for maintaining a connection between
dsw:IndividualOrganism and the proposed dwc:Individual class, although
as the definition of the dwc:Individual class was left when the subject
was dropped, it was allowed to have instances which were taxonomically
heterogeneous (unlike dsw:IndividualOrganism). In that sense, the
proposed dwc:Individual class is more like what we called "LivingEntity"
in the alternative ontology (see
http://code.google.com/p/darwin-sw/wiki/TaxonomicHeterogeneity for more
on this). At this point, I have lost interest in the dwc:Individual
class proposal, since with DSW we are accomplishing what I wanted to do
with that proposal (i.e. provide clearly defined class names that could
be used with rdf:type, to provide a means to infer duplicates, and allow
for resampling). In particular, we reached the conclusion that the
dwc:xxxxxxID terms were not useful in the context of RDF since their
meaning was not clear. Instead, we defined new terms to connect the
classes that had clear domains and ranges, so dwc:individualID is not
really relevant to the discussion in the context of DSW.
