....to them. It also provides users with a lightweight mechanism for extracting the shared knowledge and interests of their co workers. Related Projects Other systems have been designed to deal with the concept of information filtering and event notification. An example of such a product is Khronika [6 8], a software event notification service that was designed to support the selective awareness of planned and electronic events. The project drew attention to the fact that information about events is often time dependent and therefore needs to be received at a relevant time. Tickertape is similar ....

....control, feedback, and intentionality, three prerequisites for privacy, at very little cost in terms of intrusiveness. Big Brother would have a difficult time at EuroPARC, both because his access is restricted and because users can hear him coming. KHRONIKA: AWARENESS OVER TIME Khronika (L vstrand, 1991) is a software event notification service that supports selective awareness of planned and electronic events. Khronika is related to online calendar systems, but supports a more general notion of events than most. It announces when a video connection has been made, reminds users about upcoming ....

....of event notification emphasises our focus on medium rather than mechanism. Rather than derive importance or relevance of events from some representation of activity, users can configure the system to provide notifications that are suitable. This is similar to the approach of Khronika (L vstrand 1991), which supports a range of flexible practices by a focus on information rather than action (Dourish et al. 1993) Composing Attachments: Attachments can be associated with other Attachments to create composites. The model we use is that each Attachment has an empty slot which will represent ....

....to capture. However, if users can define new events, conditions under which they are generated, and means to represent them in the user interface, it is not necessary that these are described in system oriented terms (as with, for example, the pubcall event provided by the Khronika system L vstrand 1991). This approach is consistent with our emphasis on the system as a medium to support activities without representations of what those activities might be. Thus the shared workspace client supports incremental customisation of surface and deep system features with a range of techniques. These ....

....more on the semantic nature of the information being sent in the message and its destination(s) whereas events are simpler. In effect, semi structured messages can be viewed as a semantic extension and specialisation of events with events in COLA are closer to the use of events in Kronika (L vstrand, 1991). 5. Functional Architecture and Services The COLA platform, a number of simple applications and a platform browser which allows direct user access are currently being developed beyond an existing prototype. The prototype contains a fully working event model and a set of skeleton support services, ....
