Hello Group,
I have received the permission from Andrea Aime to email the geoserver users/developers about this topic.
I am working on an experimental conceptual geographic application that
pertains to, (yes I know the most overused word in the universe the last couple of years or so), social networking.
I am looking for people who may want to collaborate on this project. I am using a coverage store currently, but obviously this is no good for large graphs.
