Activity-Centred Tool Integration Using Type-Based Publish/Subscribe for Peer-to-Peer Tool Integration

This paper is concerned with integration of heterogeneous tools for system development. We argue that such tools should support concrete activities (e.g., programming, unit testing, conducting workshops) in contrast to abstract concerns (e.g., analysis, design, implementation). A consequence of this is that tools — or components — that support activities well should be integrated in ad-hoc, dynamic, and heterogeneous ways. We present a peer-to-peer architecture for this based on type-based publish subscribe and give an example of its use.
