• Logical architecture strawman for provenance systems

  Authors: Luc Moreau, Liming Chen, Paul Groth, John Ibbotson, Michael Luck, Simon Miles, Omer Rana, Victor Tan, Steven Willmott, Fenglian Xu

  The purpose of this document is to propose a logical architecture for a provenance system. The logical architecture is specified independently of specific technologies. Specifically, we introduce ourThe purpose of this document is to propose a logical architecture for a provenance system. The logical architecture is specified independently of specific technologies. Specifically, we introduce our definition of provenance in the context of service-oriented architectures, and we identify the different roles that exist in a provenance system.

• A proof of concept design for provenance

  Authors: Fenglian Xu, Alexis Biller, Liming Chen, Victor Tan, Paul Groth, Simon Miles, John Ibbotson, Luc Moreau

The term provenance however lends itself to several possible conceptions, and our initial step in the EU Provenance project was to design and implement a simple system to articulate our conception of provenance. This system, termed the pre-prototype, is based on a conceptualized process for baking a Victoria Sponge Cake. This report describes the cake baking scenario, presents some provenance-type questions that can be asked about the baking process and provides an implementation of the cake baking process within a service-oriented architecture framework that can answer these questions using collated provenance data.

• Standardisation of Provenance Systems in Service Oriented Architectures --- White Paper

  Authors: Luc Moreau, John Ibbotson

  This White Paper presents provenance in computer systems as a mechanism by which business and e-science can undertake compliance validation and analysis of their past processes. We discuss an openThis White Paper presents provenance in computer systems as a mechanism by which business and e-science can undertake compliance validation and analysis of their past processes. We discuss an open approach that can bring benefits to application owners, IT providers, auditors and reviewers. In order to capitalise on such benefits, we make specific recommendations to move forward a standardisation activity in this domain.

Given that documented history, the object attains an authority that allows scholars to appreciate its importance with respect to other works, whereas, in the absence of such history, the object may be treated with some skepticism. Our IT landscape is evolving as illustrated by applications that are open, composed dynamically, and that discover results and services on the fly. Against this challenging background, it is crucial for users to be able to have confidence in the results produced by such applications. If the provenance of data produced by computer systems could be determined as it can for some works of art, then users, in their daily applications, would be able to interpret and judge the quality of data better. We introduce a provenance lifecycle and advocate an open approach based on two key principles to support a notion of provenance in computer systems: documentation of execution and user-tailored provenance queries.
