I’m currently looking to do something similar but for organisations working in the space of the public service internet (best way I can describe it right now). But its got to be collaborative and the connections between them isn’t just their location, but their focus, their specialities, etc. On top of all this is the common connections between them.
I’ve been considering a number of things including Tagtool, some light semanticweb technology, a distributed model like Friend of a Friend and Human.txt. Been also considering scraping or getting the data from other sources like linkedin too.
What I’m doing is really recreating a customer relationship management system (CRM) like Salesforce but open, collaborative and distributed. Someone must have done this already?
