Hi Marcus,

My thoughts...

1. swe:codespace is byReference only, and it should reference the MappedFeatureObservationMethod201012.rdf classifierscheme (on the subversion at https://www.seegrid.csiro.au/subversion/CGI_CDTGVocabulary/tags/SKOSVocabularies).

                <swe:codespace xlink:href="http://resource.geosciml.org/classifierscheme/cgi/201012/mappedfeatureobservationmethod"/>

2. After reading the scope notes for swe:label ("Textual label for the data component . This is often used for displaying a human readable name for a dataset field or a process input/output"), it appears that we should use swe:label for the human-readable bit. (I can't decipher the scope notes for swe:value - " Value is optional, to enable structure to act as a schema for values provided using other encodings".  Any insight on that one?)


3. Use swe:identifier for the http-uri of the value


4.  I think you can also use the "id" attribute of swe:Category if you want to reference it later in your document.

And all the above uri's resolve!! ;)

I'm updating the BGS instance document to use RC3 rather than RC2.

I need to change

to use swe:Category instead of CGI_Term. I'm not sure how the SWE elements work and can't remember the examples from the meeting. The Edinburgh meeting notes (https://www.seegrid.csiro.au/wiki/CGIModel/EdinburghModelAgendaAndNotes) mention that the qualifier was to be put in an extension but I can't remember how this is implemented. Also, I'm using a URI for the value rather than separate codeSpace and value elements as swe:Category does. Would it be best to switch to using codeSpace and value elements or do I use the identifier element for the URI and label instead of xlink:title?




            <swe:identifier> http://resource.geosciml.org/classifier/cgi/MappedFeatureObservationMethod/201001/compilation</swe:identifier>







            <swe:codeSpace> http://resource.geosciml.org/classifier/cgi/MappedFeatureObservationMethod/201001/</swe: codeSpace>
