# PREMIS (PREservation Metadata: Implementation Strategies)

NEW! Implementing Preservation Repositories For Digital Materials: Current Practice And Emerging Trends In The Cultural Heritage Community. (PDF:668K/66pp.)

The OCLC Office of Research, OCLC Member Services, and RLG are pleased to sponsor the formation of a working group aimed at the development of recommendations and best practices for implementing preservation metadata.

In 2001-02, OCLC and RLG convened an expert working group, reflecting a variety of institutional and geographical backgrounds, to consider the types of information falling within the scope of preservation metadata. The group's efforts culminated in the public release of A Metadata Framework to Support the Preservation of Digital Objects (PDF:696K/54pp.), a comprehensive metadata framework describing the information necessary to carry out, document, and evaluate digital preservation processes.

Using the metadata framework as a conceptual foundation and starting point for its work, the PREMIS working group will carry forward the activities of the first working group. The focus of the PREMIS group will be on the practical aspects of implementing preservation metadata in digital preservation systems.

## Objectives

The working group's objectives include:

- An implementable set of "core" preservation metadata elements, with broad applicability within the digital preservation community
- A data dictionary to support the core preservation metadata element set
- Examination and evaluation of alternative strategies for the encoding, storage, and management of preservation metadata within a digital preservation system, as well as for the exchange of preservation metadata between systems
- Pilot programs for testing the group's recommendations and best practices in a variety of systems settings
- Exploration of opportunities for the cooperative creation and sharing of preservation metadata

## Membership

The PREMIS group is composed of individuals representing the library, academic, museum, government, and commercial communities.

Membership is divided between the Working Group itself and an Advisory Committee. Members of the Advisory Committee will participate on a consultative basis, providing expertise in support of the Working Group's activities, and periodically reviewing and providing feedback on the Working Group's progress.

A list of individuals participating in PREMIS is available.

## Subgroup Activities

The PREMIS working group is divided into two subgroups: the Core Elements Subgroup and the Implementation Strategies Subgroup. For a description of subgroup activities, and a brief update on progress, please visit the subgroup home pages.

## Schedule

The projected time frame for the PREMIS working group's activities is twelve months (June 2003–June 2004). The results of the group's activities will be made available for public review and comment.
