Re: discoverability and crawlability

Hello Ed,

Yes, I can see granularity and direct access is an issue. It would be good
to make that clear.

How about the following two requirements?

1) Spatial data on the web should be recognizable as spatial data (by
humans, but especially by machines).
2) It should be possible to directly identify and retrieve data about
individual spatial things.

While these requirements would fulfill the need for discoverability and
crawlability, I think they are more to the point and perhaps some more in
scope.

Regards,
Frans
