[georss] Discovery of georss and other geographic information?

[Stefan F. Keller]

Josh,

There are several open questions to me about the goal and concepts of such a
protocol. I labelled CS/W heavyweight because it includes a query language
which is not needed in a pure harvesting concept. So, I don't see why "yet
another protocol" when there is WFS or when there are protocols (with tools)
like OAI-PMH which comes from an even broader community including Google.
Some even say that not much more than HTTP is needed. And there are also
ideas differing from CSW metamodel about modeling of services (see the wiki
I mentioned above).

-- Stefan
P.S. Perhaps we should move this discussion over to
https://geodata.osgeo.org/servlets/BrowseList?listName=geodata ?
