Hi Simon,

Who is responsible for making the required changes for FullMoon?

Breaking news:

In the GML 3.3 SWG last week the issue of how to refer to an item from a controlled source consistently in GML was a hot topic.
To summarize the conclusion I think it goes something like this:

1.       items in controlled vocabularies should have URIs (codeList, controlledConcept, etc)
a.       this does not pre-judge how they are implemented, but obviously it is RDF/SKOS/OWL- & http-friendly
2.       Feature properties that refer to items from controlled lists (i.e. ScopedName) should be implemented using gml:ReferenceType (rather than gml:CodeType)
a.       Xlink:href should point to the concept identifier
b.       Xlink:title _may_ be used to provide a human-consumable label, so an interface can be built without resolving the URI
                                                                                       i.      (obviously this is not scalable to multi-lingual labelling)

This will get away from the ambiguity regarding what to put in @codeSpace and what in the element.

Note that
(a)     this is my interpretation of the discussion (I'm charged with writing it up, however)
(b)     it has not yet been voted on, and
(c)     would strictly only apply from GML 3.3.
However, as it doesn't break anything now and is a totally reasonable tweak to the UML-XML mapping rule, I suggest that GeoSciML consider using this rule now.

In the FullMoon context it requires that one or more of these entries in https://www.seegrid.csiro.au/subversion/HollowWorld/trunk/ClassMaps/ClassMap_ISO_19103_CSL_GML32.xml be changed:


        <entry>

               <umlClass>GenericName</umlClass>

               <gmlObjectElement xsi:nil="true"/>

               <gmlType xsi:nil="true"/>

               <gmlPropertyType>gml:CodeType</gmlPropertyType> -> probably leave alone, but try not to use GenericName in models

        </entry>

        <entry>

               <umlClass>LocalName</umlClass>

               <gmlObjectElement xsi:nil="true"/>

               <gmlType xsi:nil="true"/>

               <gmlPropertyType>gml:CodeType</gmlPropertyType> -> this should be xs:string anyway

        </entry>

        <entry>

               <umlClass>ScopedName</umlClass>

               <gmlObjectElement xsi:nil="true"/>

               <gmlType xsi:nil="true"/>

               <gmlPropertyType>gml:CodeWithAuthorityType</gmlPropertyType> -> change to gml:ReferenceType

        </entry>

How do I send a nice red face? Yes: 'qualifier on CGI_Term'. Thanks for that.

If it's an attribute I'm pretty confident that's how it would encode, if it is an element I'm a bit confused:

<gsml:lithology codeSpace="urn:cgi:classifierScheme:CGI:SimpleLithology:200811">
     urn:cgi:classifierScheme:CGI:SimpleLithology:200811
     <gsml:qualifier>sometimes</gsml:qualifier>
</gsml:lithology>

Seems nasty.

WRT your question: I'm not Full Moon expert but I would have expected you woul use a Tagged Value to define an attribute.

Hi Alistair,

Re question 1.   Ah, you mean why is 'qualifier' mandatory in CGI_Term?   I think it is just an oversight.  As far as I can tell, there was no discussion of this point at Quebec?  Probably should be optional like in v2.0.

Re question 2.   Hmm, not exactly sure how this would encode.  Your attempt is as good as I could do.

As a related question... In the UML, I have never known how to make an attribute occur in the schema as an attribute within the tag (like qualifier="sometimes"), rather than as an attribute between the tags (like <qualifier>sometimes</qualifier>).  eg; swe:AbstractDataComponent encodes its attributes within its element tag, but I can't see anything in the UML which makes it different to swe:Quantity which encodes its attributes outside the element tag.

[%20]

<swe:Quantity definition="urn:test:xxx" fixed="false">
            <swe:uom xlink:href="#ppm"/>
            <swe:value>23.6</swe:value>
</swe:Quantity>

Any ideas?

Cheers,
Ollie

Hi Ollie

The email address is registered and I've been using it since last year. Odd.

Is it an attribute like codeSpace? Would it encode as:

<gsml:lithology codeSpace="urn:cgi:classifierScheme:CGI:SimpleLithology:200811" qualifier="sometimes">
     urn:cgi:classifierScheme:CGI:SimpleLithology:200811</gsml:lithology>

Hi Alistair,

I think your email to the list bounced - your gmail account is probably not registered with the list.

Could you rephrase question 2?  Doesn't make sense to me.

Hi Everyone

Quick and easy questions concerning the new CGI_Term in GeoSciML 3.0:
1.      Why is it mandatory?
2.      Is it an attribute of CGI_Term?
Cheers
Alistair
