Industrial SOA-based applications require multiple services to interact and cooperate. We propose an approach to service composition based on the ideas from Blackboard Systems, extensively investigated in AI in 1970-80s. We combine these ideas with Onto?SOA - a SOA design framework that relies on a restricted document-oriented and ontology-based service model to provide guidelines for construction of services. The proposed Blackboard-style composition approach requires neither an extensive service model nor an explicit workflow specification. It enables composite functionality to emerge by bringing a number of services together and making them interact via a shared data repository. The emerging workflow is built on domain knowledge modeled in the respective service ontologies. We illustrate the feasibility of the proposed mechanism by an example from the e-science domain, viz. checking consistency of units of measurement in mathematical statements. [ABSTRACT FROM AUTHOR] |
