[georss] Discovery of georss and other geographic information?

[Josh@oklieb]

Stefan,

What was formerly known as Web Registry Service was always a  
combination of an OGC Catalog interface with the ebRIM metamodel. CS/ 
W 2.0 (now 2.0.1) is a revision of that interface which has also been  
propagated into the ebRIM profile. The OGC Catalog 2.0 specification  
itself is involved, since it includes a conceptual model and then two  
different concrete protocol bindings and a basic information  
metamodel, but the interface is modular and not itself at all  
heavyweight. A CS/W implementation can be very simple, as evidenced  
by the Basic Profile being tested in OWS-4, or it can be a highly  
capable enterprise-class component as in several of the ebRIM profile  
commercial products which are presently available.

As far as GeoRSS in XHTML, there were definitions and examples for  
this in an earlier version of the website which were quite easy to  
come up with. It was not clear at the time, however, what practice of  
encoding the GeoRSS elements in XHTML would be considered   
"microformat-compatible" without causing raw coordinates to be  
rendered and without, frankly, misusing XHTML attributes such as  
title. Perhaps we can circle back around at FOSS4G and come up with  
an encoding which satisfies both of these criteria.

Cheers,

Josh
