[tdwg-content] Expressing some relationships in DwC?

[Richard Pyle]

Hmmm.... watch out for that tricky word "valid".  It means different things
to botanists & zoologists. The term "accepted" is generally seen as a more
code-neutral term to mean "valid" (sensu zoology) or "correct"/"accepted"
(sensu botany).  But if you mean "valid" in the botanical sense (="validly
published", or "available" sensu zoology).  I'm not entirely sure which
sense of "valid" is meant in this context.


More fundamentally, however, I'd like to report that a number of folks at
TDWG seemed to have converged on the same idea that, perhaps, we should be
using resourceRelationship more frequently (perhaps a *LOT* more
frequently).  A lot of these terms that effectively represent the functional
equivalent to "foreign keys" might be better packaged in the more open-ended
structure of resourceRelationship.  In fact, at one of the sessions at TDWG
(I believe it was at the AudubonCore break-out session), we discussed the
idea of DwCA "2.0", which would essentially define n-number of "Cores", and
then package the relationships among them via a set of resourceRelationship
records.  This idea emerged from a discussion about how people have been
trying to "force" many-to-many sorts of data into the one-to-many DwCA
format.  The beauty of using a more generic resourceRelationship set for
this function is that it allows one-to-one, one-to-many, and many-to-many
relationships all in one structure.  It may seem klunky now, but if we used
it as a general method to describe all relationships between instances of
DwC "classes", it would become pretty straightforward, I think.

Something to think about, anyway...

Aloha,
Rich
