Hi all,

I think we may have been a bit over zealous in constraining the model by limiting the various occurrences of "proportion" in GeoSciML v3 to be CGI_NumericRange (eg: GeologicUnitPart/proportion, CompositionPart/proportion).  I have found that my available "proportion" data is in the form of "major", "minor", "dominant", "trace", etc and I am unable to deliver this data in a numeric form.  Searching back through the instance docs of Testbed3 (GeoSciML v2 allowed text or numbers) indicates that text is the common format of "proportion" data, not numbers.

Can anyone remember the reasoning behind the change to numbers only for "proportion"?  Otherwise, I suggest we change the model to accommodate text values for "proportion".

Comments please,


Ollie Raymond
