[Tdwg-guid] resolving deleted records [ Scanned for viruses ]

[Chuck Miller]

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?
