Chuck,
It's actually part of Dublin Core Metadata Terms (http://www.dublincore.org/documents/dcmi-terms/), so by convention it should be referred to as dcterms:isReplacedBy, where the name space dcterms is http://purl.org/dc/terms/. The full definition of this predicate in RDF is provided by Dublin Core (http://purl.org/dc/terms/isReplacedBy).
RDF doesn't, I guess, have a vocabulary for objects as such, they are always referred to by URIs. Hence, what gets defined are the predicates.
Regards
Rod

Forgive my ignorance again, but am I correct that dc: in this context refers to a namespace. Is that namespace Dublin Core, Darwin Core, or other? I can't find "isReplacedBy" in Dublin Core.
Are you using "isReplacedBy" as an RDF predicate?
How would the specific definition of "isReplacedBy" be recorded? Is there going to be a TDWG TAG discussion about controlled vocabulary/ namespace for predicates as well as objects? I can see predicates all over the UML diagrams at the Ontology WIKI, but I don't see them listed anywhere with definitions?
Just looking at the CoreOntology UML diagram http://wiki.tdwg.org/twiki/bin/view/TAG/CoreOntology there are many, many predicates: hastate hasValue inUnits onProperty aboutStructure hasElements describedBy description type typifiedBy typificationOf by from to
and many, many more. How will we arrive at the unambiguous meaning of these predicates? Is there a working group for this?
Thanks, Chuck

It is usually mostly blank in most cases (except the name, perhaps an author, the PK, the parentFK) but I may leave a comment in the internal notes field with some explanation to help those who follow. Of course, what constitutes the 'record' will depend on the database schema for which IF is closer to the data warehouse model rather than a fully normalized model.

So is everybody happy with the following:
if a record is deleted then dc:isReplacedBy is set to the LSID of the record that replaces it. If it isn't replaced by anything, it's just deleted because it was entered in error, then isReplacedBy is set to its own LSID
Paul do you blank out the rest of the record?
