This might be too far off the original idea... But: It might be
interesting to look into a more disconnected way of managing
geospatial data with the Web. As in having servers advertize latest
changes in geometry and attributes using GeoRSS and clients picking
these up and integrating them
Hi,
Yes Smallworld did a lot of innovation in the area of version management and
long transactions some 20 years ago, I was quite involved in all that. The
technical paper you mention is at archive.org, a great resource for finding
web pages that have disappeared!
Arnulf, that's exactly what the OGC Geosynchronization spec describes! Servers
advertise their changes in a GeoRSS feed -- where the content element
describes the change in WFS-T XML. It's nicely loosely coupled, because as you
eloquently state, clients can decide what they want to do with the

I agree. I think that we have a way to go yet to have something comparable to

functionality.

within the database. This works well within an
