I thought the information below might be of interest to the members of this list. I would especially draw your attention to their efforts to automatically capture provenance information about the computing environment and how it was used to create a particular digital object. It is interesting to see that aerospace professionals are interested in the archival/records management concept of provenance and in using data grids to establish infrastructure independence.
The ERA Research staff is also testing data grid and rules-based technologies to learn more about establishing persistent archives that are scalable, evolvable, and extensible. We are using the Storage Resource Broker (SRB) (http://www.sdsc.edu/srb/index.php/Main_Page) and the integrated Rule Oriented Data Systems (iRODS) (http://irods.sdsc.edu/index.php/Main_Page). Both of these technologies were developed by a team headed by Dr. Reagan Moore at the San Diego Supercomputer Center.

AeroGrid is part of a larger German government national data grid initiative. The text below is taken from a larger report on this initiative. That report can be found at:

AeroGrid
Grid-Based Cooperation between Industry, Research Centres, and Universities in Aerospace Engineering D-Grid II, Aerospace Engineering The AeroGrid project aims at providing an efficient grid-based working environment for the national aerospace research community. The AeroGrid environment will be a permanent and effective grid infrastructure for the cooperation between industry, research centres, and universities in aerospace engineering and research.
Compared to other industrial sectors, most aerospace research is carried out in public and governmental institutes. In the field of computational fluid dynamics (CFD), industry often uses innovative codes which are jointly developed by research centres, such as DLR, and universities. The AeroGrid environment allows virtual organizations to cooperate in research and development projects, to always use up-to-date program versions, data, and compute resources across all locations, and to document and trace the detailed history of a
computational process that leads to a certain result ("Provenance").
The design of the AeroGrid environment addresses two important requirements:
. Suitability for daily use, especially for the productive operation by the service provider after the end of the project.
. Applicability to similarly organized communities in science and industry.
The integration of a Provenance service which records detailed information of all conducted execution steps, increases the dependability of the results and improves the user's confidence in their quality. The Provenance service used in AeroGrid will be provided to all D-Grid projects as a standard service for Provenance recording and querying.
Within the project, the grid environment will be evaluated with the following usage scenarios from the turbine simulation domain:
. Usage of compute resources via the AeroGrid.
. Collaboration during the design of new engine components.
. Cooperative further development of the DLR CFD code TRACE.
The AeroGrid environment will consist of two different user interfaces, a Web portal based on the GridSphere server, and the data management client application DataFinder. Both user interfaces will be customized to support the various usage scenarios.
