Subject: RE: [emergency] RE: EDXL-DE 2.0 for the F2F - Objectivity, Subjectivity and Interpretation.

I believe that we envisioned much more for OASIS Where than just
GML-based Points and Polygons so this might just be a terminology

If all you expect to do by Wednesday is to put the same GML coordinate
system used in RM into DE then we are fine. 

If you want to put more advanced concepts like multi-points, line
segments, or indicating the order of accuracy for multiple ways of
describing the same location then we are not yet there.

I agree but if we want a sample schema by next Wednesday for EDXL DE 2.0
I think we may be out of luck as the OASIS Where profile is not yet at
the point of producing angle brackets.

So this is on the list.  I was planning to advocate moving to our
GeoOASIS where GML profile for targetarea geographic objects.

I concur.
