Requirements for Collaborative Components
Web collaboration requirements:
Capture and propagation of application events: user actions in one application are reflected in other applications
Selection of relevant events: not all events need to be shared
Specification of event target components: each event must have the recipient component which knows how to interpret the event
Transfer of arbitrary data: enables information exchange among collaborative tools
Access to the collaboration session state: used to support collaboration awareness or assure synchronized access to the session resources
Integration with the Web environment: encapsulation of Web specific communication mechanisms enables creation of portable and generic applications
