Hi Rick,

You could do something like this using the com.bbn.openmap.layer.link
package, which involves the client and server using the OpenMap Link
protocol to exchange information. Map objects can be pushed both
ways over the link between clients and server. You'd have to
introduce any code you'd want for verifying information pushed to the
server, or for authorizing clients to write to the database.

You could also use GML (geographic markup language, a geospatial XML
schema), but there isn't really support within OpenMap for GML right
now. That would be more of the 'standards' approach, but there would
be more work to that.

Regards,

Don
