PROVENANCE Enabling and Supporting Provenance in Grids for Complex Problems Contract Number : 511085 An Architecture for Provenance Systems Executive Summary

This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to different technologies.
