What is a city information network for?

I'm setting up a City Information Network meeting in Brighton in March so I've started thinking about what it will be and how to run it.
It will be a forum for people to discuss city information resources, something like an event we ran back in 2000 - see the notes on our website. This time I think we need to include information from the whole city, not just what we called community information, ie not for profit and charitable/community/voluntary and public.
This reflects the work we've done since then on theplacetobe.net which is one of very few cross-sector bodies considering local information issues in a practical way.
This is a growing area of interest often referred to as civic knowledge management.
In the internet age this means [to me] the concerted effort required to ensure the best quality information is available for and about a local community.

Healthy communities
As an example take the health of the local community and its access to information which may help maintain or improve their health.
To get the best quality information we need the Council to collaborate with the Primary Care Trust to provide information about health and social services in the area. We want the Argus to chip in with its features on health which provide accessible advice and pointers on a range of local health issues.
Then there's a health section in ESCIS - a directory of local community information published by the Council and maintained by library staff.
And don't forget information about health services in the area on the sites of the people who provide them - dentists, doctors, alternative therapists and more - just look at the 1,350,000 results when you put brighton UK + health into Google

A forum for informaton providers
So the City Information Network could provide a local forum to address a number of issues:
-- what are the key health information resources which everyone in the city should know about?
-- what do we think of their quality?
-- how can the people providing these resources improve their information service?
-- is it possible to the improve access to and the quality of the information services by working together?
-- how can the p2b.net search engine and other shared information resources help improve the situation?
