[Auscope-geosciml] GeochronologicEraand ScopedName [SEC=UNCLASSIFIED]

Mon Mar 22 11:45:43 EDT 2010

Apologies for changing my mind. This is a work-in-progress. 
The current discussion has allowed me to clarify the arguments, and also the
recent discussions in the GML 3.3 SWG, relating to the use of xlinks. 

I hope this is not a disruptive change, so I trust it can be done smoothly.

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?topi
cparent=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.

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
