Approach for Dynamically Composing Decentralised Service Architectures with Cross-Cutting Constraints

The emergence of open, composable Internet services and mashups means that services cannot be composed in a centralised manner. Despite this, cross-cutting constraints might exist between services, stemming from, e.g., security. Especially when used with mobile devices, these service compositions need to be constructed at runtime. This paper proposes a knowledge-based approach for dynamically finding and validating decentralised service compositions while taking into account cross-cutting constraints. The approach is exemplified with a case of a shopping mall portal.
