You are on the wrong listserv. Many GIS-L list members believe this is =
alternative to commercial software support. The list traffic here is =
typically, "Which button do I push on software X to get result Y."
I would suggest that you join the geowankers listserv, where the =
intersection of the spatial web and semantic web is the focus.
Here is the geowankers URL:

Everyone is serving out datasets based on exisiting features such as roads,=
railways and contours.
