PASOA: Provenance Aware Service Oriented Architecture



The proposed research will investigate the concept of provenance and its use for reasoning about the quality and accuracy of data and services in the context of e-Science. The problems of determining the orign of a result or deciding when results of analysis are no longer valid become important concerns in open Grid environment, where providers are dynamically organised in virtual organanisations to offer services to the community. In this context, provenance data is an annotation able to explain how a particular result has been derived. This project will identify the nature of "provenance", will investigate the algorithms to generate it and to reason about it, will establish their correctness and will integrate a prototype into existing e-Science projects. With our principled design and the project outcomes (provenance requirements, new algorithms for supporting provenance, and implementation), we will provide an answer to the problem of trusted systems in e-Science as identified in the call for proposals.
