sf-active is a semi-retired, mysql-based fork of the active project.
The active code was a multimedia, open publishing website for the n30-WTO protest in Seattle 1999.
From an open hacklab in a downtown storefront, people posted real-time web updates (txt/img/video/etc) as huge protest crowds disrupted the WTO and scrapped with riot police, tear gas & stun grenades.
The non-stop stream of info from indymedia that day made CNN seem old & slow. The concept quickly spread to over 170 world cities.
The IMC Network was probably the first large-scale web2/social tech that rapidly expanded and repeatedly impacted the real world in new ways.
The sf-active cms runs a couple dozen local IMC sites but it's painfully out-dated.
See cms.indymedia.org to read about plans for nextgen imc code.
