[Auscope-geosciml] GeochronologicEra and ScopedName [SEC=UNCLASSIFIED]

Looking back at the discussion notes it was Simon who was previously arguing we replace ControlledConcept with ScopedName!

>From Simon's description of the semantics below it would appear we should use ControlledConcept for any term referencing a concept, which would include GeochronologicalEra name. More generally should we reverse the decision to replace ControlledConcept with ScopedName in all those cases where the term used will always reference a concept?

Semantically they are almost the same - in both cases there is a notion of an item from a set controlled by some authority - but a ScopedName is term-centric (and thus not localizable) while a controlled-concept is concept-centric (and as SKOS has shown us, a concept can have many labels).
(There is also a GeoSciML model for controlled-concept, giving it some extra properties. These are essentially trivial in practice.)

Overall,
1. controlled-concept is more general, and
2. there is not an existing GML encoding rule to fight
If we apply our own encoding rule (i.e. an entry in the classmap) that it shall be implemented as gml:ReferenceType, then we don't even need to play with tagged values to get to a good place.

This sounds like a semantic question.

I'm not sure yet I fully understand the difference between ScopedName and ControlledConcept.
Nevertheless, the attribute name is controlled by a vocabulary (ie: the ICS Strat Chart)... so it sounds like a ControlledConcept to me.

Hmmm, we took the decision at Quebec to replace all the ControlledConcept attributes with ScopedNames......

Action 6. Replace ControlledConcept<https://www.seegrid.csiro.au/twiki/bin/edit/CGIModel/ControlledConcept?topicparent=CGIModel.Quebec2009ModelDesignTaskGroupAgenda> , with ScopedName<https://www.seegrid.csiro.au/twiki/bin/edit/CGIModel/ScopedName?topicparent=CGIModel.Quebec2009ModelDesignTaskGroupAgenda> , replace deprecated CGI_Values, CGI_ValueTerms and CGI_Term with ScopedName<https://www.seegrid.csiro.au/twiki/bin/edit/CGIModel/ScopedName?topicparent=CGIModel.Quebec2009ModelDesignTaskGroupAgenda> or CGI_Term (qualified ScopedName<https://www.seegrid.csiro.au/twiki/bin/edit/CGIModel/ScopedName?topicparent=CGIModel.Quebec2009ModelDesignTaskGroupAgenda> ) as per pattern established 23 September 2009. Use ScopedName<https://www.seegrid.csiro.au/twiki/bin/edit/CGIModel/ScopedName?topicparent=CGIModel.Quebec2009ModelDesignTaskGroupAgenda> or CGI_Numeric wherever possible.

<<We want to used the ICS Strat Chart as our vocabulary, so shouldn't GeochronologicEra be using a "ScopedName" type for its name?>>

This will most likely be a  "ControlledConcept " I guess..

The more I try to wind up things for GeoSciML 3, the more I find...

We have made the NamedAge attributes of GeologicEvent of type "GeochronologicEra".  The name of a GeochronologicEra is of type "LocalizedGenericName" (inherited from TimeOrdinalEra).

We want to used the ICS Strat Chart as our vocabulary, so shouldn't GeochronologicEra be using a "ScopedName" type for its name?

Cheers,
Ollie
