Re: Universal Core?

Well, I would not dismiss uCore.

uCore is being "honchoed" by the US Defense Information Services Agency 
(DISA) on behalf of the DoD/Intel community. uCore is NOT designed to be 
everything to everyone. A good overview may be found at: 
http://www.defenselink.mil/cio-nii/docs/UCore_Overview.pdf . Another web 
site is http://data.army.mil/datastrategy_universal_core.html .

The "where" elements of uCore use the OGC Geography Markup Language (GML) - 
http://colab.cim3.net/file/work/SICoP/2008-02-05/DoDCoI10162007/PShaw10162007.ppt

uCore is NOT designed nor meant to be a "universal" data warehousing or 
ontology project!

That said, as uCore does use GML to encode "where" content, and GML is based 
on ISO 19107, then by definition uCore "where" is based on the semantics and 
information model for Features (geography) as defined by the OGC/ISO 
communities.

Cheers
