Group Abbreviation:
pe-rg
Group Name:
Preservation Environments RG
Area:
Research Applications
Group Leadership:

| Andre Merzky | andre@merzky.net | Secretary |
Group Summary:
The Preservation Environments Research Group of the Grid Forum will develop a GGF Informational Document for Persistent Archives based on virtual data grid technology.The proposed Information Document will serve two purposes:
1) Describe to the preservation community best practices for implementing distributed preservation systems
2) Identify for the grid community the consistency constraints that are required between grid services for a viable preservation system.
Charter Focus/Purpose and Scope:
The PERG group will use the federated data grids established by the Grid Interoperability Now working group to demonstrate preservation concepts. For a preservation environment to be viable, it must be possible to extract all records along with their authenticity and integrity metadata and export the contents into another preservation system. By using the GIN data grid testbed, a demonstration of viability will be conducted.
The PERG group will also examine how rule-based data management systems can be used to automate application of preservation management policies, and use rules to validate trustworthiness of digital repositories. Rule-based systems control the execution of remote micro-services, and manage state information generated by each micro-service. A specific focus will be the integration of grid services under rule-based management.
Exit Strategy:
On successful demonstration of the viability of preservation environments based on data grids, the research group will be recast as a Preservation Working Group to document at least three instances of preservation environments. These environments will demonstrate that data grid federation provides a viable mechanism for demonstrating preservation viability.
Given the demonstration of data grid technology within the GIN working group, the next step is the demonstration of rule-based management of grid services that achieve preservation objectives of authenticity and integrity.
Goals/Deliverables:
Title: Long-Term Digital Archive Requirements
Abstract: The core requirements for long-term digital archives can be expressed as management policies for both the digital records and the infrastructure that supports the digital records. Sixteen core requirements have been identified. This document explains the significance of each core requirement, and proposes multiple levels of support for each core requirement.

Seven Questions:
1. Is the scope of the proposed group sufficiently focused?
Yes. The group focuses on grid services required to implement preservation environments.
2. Are the topics that the group plans to address clear and relevant for the Grid research, development, industrial, implementation, and/or application user community?
Yes. The ability to organize and manage grid services is a generic capability needed by other data management applications including digital libraries and real-time sensor systems.
3. Will the formation of the group foster (consensus-based) work that would not be done otherwise?
Yes. The preservation community has multiple projects and meetings on preservation processes. They need an interaction mechanism with the Grid community.
4. Do the group's activities overlap inappropriately with those of another OGF group or to a group active in another organization such as IETF or W3C?
The group's activities are complementary to those of the preservation community, which focus on principles rather than implementations.
5. Are there sufficient interest and expertise in the group's topic, with at least several people willing to expend the effort that is likely to produce significant results over time?
Yes. The group has contacts with the major preservation research projects in the US, the UK, the EU, Taiwan, Australia.
6. Does a base of interested consumers (e.g., application developers, Grid system implementers, industry partners, end-users) appear to exist for the planned work?
Yes. The US National Archives and Records Administration is supporting the group.
7. Does the OGF have a reasonable role to play in the determination of the technology?
Yes. The ability to apply grid services for preservation expands the range of applications of grid technology.
