Towards declarative characterisation and negotiation of bindings
Øyvind Hanssen · 2005
This paper addresses negotiation of bindings in open systems, and in particular how to characterise the capabilities of heterogeneous platforms, and communication channels. Based on a middleware architecture supporting policy-governed binding, negotiation is about selecting suitable policies for bindings at run-time. We propose a model for declarative expressions based on a hybrid of declared and rule-based conformance, and composition operators. We also propose a scheme for how the middleware can support automatic characterisation of resources or other relevant capabilities and composition of these, based on the declarative expression model.
