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...

Hi Markus,

Yes, I believe this would cover both the cases I need, I think, when accompanied by nomenclatural status = misspelling / nomenclatural status = nomen nudum... - comments, anyone?
Cheers - Tony

Hi Tony, thanks for these practical questions. See inline for answers. Markus
I have a few nomenclatural relationships between name that I would like
to
express using DwC, and would like to know the preferred way to do this if any. The relationships are as follows:
(1) Point a nomen novum to the basionym it replaces. From reading there
was formerly a concept basionym/basionymID, apparently this is now replaced with originalNameUsage/originalNameUsageID. So one quesiton is, is this sufficient to infer this is a basionym, when accompanied by noneclaturalStatus = 'nomen novum'? yes, that is exactly right. As far as I understand the term basionym is
more of
a botanical term and was not used as the final dwc term therefore.
(2) Point an orthographic variant to the name which it is a variant of
(whether or not the latter is now the accepted name). In other words, if name A is a variant of name B which is now a synonym of name C, I capture the A=>C relationship with a synonym assertion, but I want a way to capteure the A=>B relationship too. This is only possible with an extension I am afraid. For example the
generic
dwc relationship one: http://rs.gbif.org/extension/dwc/resource_relation.xml
(3) Point a nomen nudum to a validly published instance that comes later
(or do the same in reverse, i.e. this name was preceded by xxx as a nomen nudum). Again, this should be independent of whether the validly published name is an accepted name or now a synonym of something else. same problem as above. I begin to wonder if a new term dwc:validNameUsageID would solve this issue gracefully and remove the need for a relationship extension.
Advice appreciated,
