This project intends to explore generic data models for provenance metadata. The first stages of the work involves investigating the provenance requirements of different applications domains.. The next stage attempts to generalize these data requirements into a single generic model for that group of applications. The generic model then is used as a basis for investigating issues on effective management of the metadata. Domain experts can express issues about their requirements without considering the details of the system implementation. If successful, the project will explore the efficiency of the provenance management within specific applications areas. The proposal will also explore optimization strategies and opportunities provenance metadata management which would include optimizations of storage requirements and operations, such as recursive queries.

本项目旨在探索来源元数据的通用数据模型。工作的第一阶段涉及调查不同应用程序域的来源需求。下一阶段尝试将这些数据需求概括为该应用程序组的单一通用模型。然后将通用模型用作研究有效管理元数据问题的基础。领域专家可以在不考虑系统实现细节的情况下表达有关其需求的问题。如果成功，该项目将探索在特定应用领域中出处管理的效率。该提案还将探索元数据管理的优化策略和机会，其中包括存储需求和操作的优化，例如递归查询。
