COBWEB is a collaborative idea sharing platform. Ideas are shared by the use of spider diagrams (read: mind maps), but there is no reason why the data could not be represented in different ways by the use of plugins.
The COBWEB platform is service orientated, this means that when sharing a session between more than one person the service only exists when it needs to, for example, when a user has not selected to share a session the session is not shared. Only once a user has opted to share a session does the session become shared.
COBWEB is currently being rewritten to allow for multiple sessions within one program.
