[auscope-geosciml] Borehole gsml:coredInterval GM_Envelope vs GM_Object [SEC=UNCLASSIFIED]

[Bruce.Simons at dpi.vic.gov.au]

No reply. 
I remember the discussion, but not the result, and Wiki wasn't helpful (at 
least I couldn't find it - maybe I was taking notes).

Cheers

..another email that slipped through in my Xmas email storm...
 
Bruce, did you get a reply from anyone on this?  I don't recall any 
decision on this at Rome.  We talked about borehole surveys vs gml:curve, 
but not about your question as I recall.
 
Having said that, I think your proposal is to change the data type is 
correct.  I'm not sure why we modelled CoredInterval as gml:Envelope.  Is 
there a member of the Boreholes subgroup (from circa Melbourne 2007) that 
can tell us the reason why gml:Envelope was used (or if it is just an 
error).
 
Cheers,
Ollie

Subject: [auscope-geosciml] Borehole gsml:coredInterval GM_Envelope vs 
GM_Object
 
The discussion on the TWiki on GM_Envelope vs GM_Object for 
gsml:coredInterval has: 

"For sa:shape and gsml:shape we have used GM_Object, which allows the use 
of gml:LineString. For gsml:coredInterval we have used GM_Envelope which 
allows gml:Envelope. gml:LineString allows gml:id as well as srsName, 
whereas gml:Envelope doesn't allow gml:id. This precludes referring to the 
same geometries described in the Observations (see "Multiple Properties" 
discussion above). 
More importantly it requires gml:lowerCorner and gml:upperCorner, rather 
than the two gml:pos values gml:LineString uses. This is inconsistent and 
wrong, the gsml:coredInterval should be treated the same as the 
Observation interval."

My recollection from Rome was we decided to change the data type on 
coredInterval. Is this correct?
