Decentralized Information Spaces for Composition and Unification of Services

The DISCUS project focuses on forming temporary alliances among existing legacy systems that may span organizational boundaries, to rapidly deal with a unique and temporary problem. This integrated suite of tools, termed a Summit, will help operational teams to achieve quick understanding and resolution of the problem at hand.

A summit is formed by composing services from different Service Spaces, where each service space is an autonomous collection of services allowing selective access to its services. The extent of access allowed by a service space to external entities is based on their credentials and the nature of the problem, thus creating a dynamic trust model. A Treaty, representing a contract, is then formed amongst the service spaces of these participating services.

Each service space enforces normative interaction between the ‘enlisted’ services of a summit by intercepting and verifying every operation with the relevant treaty. Once the services within a summit have accomplished their mission, the summit can be dissolved.
