[tdwg-content] Idea for Discussion, Differentiating between "type's" of identifiers

I have been thinking about the following pattern. In part after looking at
the GBIF vocabulary.

I am not sure if it is even a good idea but might be worth some discussion.

For those fields that have both a string and "ID" form maybe the following
pattern might be useful

hasScientificName = string form
hasScientificNameURI = Resolvable LOD compliant identifier
hasScientificNameLSID = LSID identifier which could be resolvable once you
add the "http:proxy" etc.

This allows all three forms to be included if desired, it also provides a
hint as to how the field should be interpreted or resolved.

One group could also provide a mapping service so that each record does not
need to include all three forms, but would allow systems
to find the matching LSID for a given URI or vs. versa.

My concern was that it would be difficult to infer how a scientificNameID
should be interpreted by other systems.

Is this an LSD, is it a URI, is it a UUID etc. ?

This impacts the structure of the RDF.

* Note that the actual identifiers might not be correct, the example below
is more about the form of the RDF
* For instance, I don't think it is probably correct to see the COL LSID as
just a namestring
* Also in this example the GNI name does not exactly match the string name

<dwc:hasScientificName>Puma concolor (Linnaeus 1771)</dwc:hasScientificName>
<dwc:hasScientificNameURI rdf:resource="
<dwc:hasScientificNameLSID rdf:resource="urn:lsid:catalogueoflife.org:

Some system may choke on the LSID form assuming that it uses a standard
resolution mechanism

So it might be best to use this form
