There are a large number of metadata standards and initiatives that have relevance to digital preservation, e.g. those designed to support the work of national and research libraries, archives and digitization initiatives. This paper introduces some of these, noting that the developers of some have acknowledged the importance of maintaining or re-using existing metadata. It is argued here that the implementation of metadata registries as part of a digital preservation system may assist repositories in enabling the management and re-use of this metadata and may also help interoperability, namely the exchange of metadata and information packages between repositories.

Critical Arguements
CA "This paper will introduce a range of preservation metadata initiatives including the influential Open Archival Information System (OAIS) reference model and a number of other initiatives originating from national and research libraries, digitization projects and the archives community. It will then comment on the need for interoperability between these specifications and propose that the implementation of metadata registries as part of a digital preservation system may help repositories manage diverse metadata and facilitate the exchange of metadata or information packages between repositories."
Conclusions
RQ "The plethora of metadata standards and formats that have been developed to support the management and preservation of digital objects leaves us with several questions about interoperability. For example, will repositories be able to cope with the wide range of standards and formats that exist? Will they be able to transfer metadata or information packages containing metadata to other repositories? Will they be able to make use of the 'recombinant potential' of existing metadata?" ... "A great deal of work needs to be done before this registry-based approach can be proved to be useful. While it would undoubtedly be useful to have registries of the main metadata standards developed to support preservation, it is less clear how mapping-based conversions between them would work in practice. Metadata specifications are based on a range of different models and conversions often lead to data loss. Also, much more consideration needs to be given to the practical issues of implementation."

Title
Digital preservation: Where we are, where we're going, where we need to be
CA Digital preservation will begin to come into its own. The past five years were about building access; now standards are coalescing and more focus is being paid to actual preservation strategies. Major legal obstacles include the DMCA, which restricts what institutions can do to preserve digital information. There are economic challenges, and we do not really know how much digital preservation will cost.
Phrases
<P1> There will be change, there is no guarantee that you can pick a technology and stay with it for ten years. We have to have an awareness of technological change and what's coming -- we listen to peers and the larger institutions that are taking leading and bleeding edge roles, and we make wise decisions. So in this case it is OK to be trailing edge and choose something that is well-established." (p.3)

RLG Best Practice Guidelines for Encoded Archival Description
These award-winning guidelines, released in August 2002, were developed by the RLG EAD Advisory Group to provide practical, community-wide advice for encoding finding aids. They are designed to: facilitate interoperability of resource discovery by imposing a basic degree of uniformity on the creation of valid EAD-encoded documents; encourage the inclusion of particular elements, and; develop a set of core data elements.

<CA> The objectives of the guidelines are: 1. To facilitate interoperability of resource discovery by imposing a basic degree of uniformity on the creation of valid EAD-encoded documents and to encourage the inclusion of elements most useful for retrieval in a union index and for display in an integrated (cross-institutional) setting; 2. To offer researchers the full benefits of XML in retrieval and display by developing a set of core data elements to improve resource discovery. It is hoped that by identifying core elements and by specifying "best practice" for those elements, these guidelines will be valuable to those who create finding aids, as well as to vendors and tool builders; 3. To contribute to the evolution of the EAD standard by articulating a set of best practice guidelines suitable for interinstitutional and international use. These guidelines can be applied to both retrospective conversion of legacy finding aids and the creation of new finding aids.

Archiving The Avant Garde: Documenting And Preserving Variable Media Art.
Archiving the Avant Garde is a collaborative project to develop, document, and disseminate strategies for describing and preserving non-traditional, intermedia, and variable media art forms, such as performance, installation, conceptual, and digital art. This joint project builds on existing relationships and the previous work of its founding partners in this area. One example of such work is the Conceptual & Intermedia Arts Online (CIAO) Consortium, a collaboration founded by the BAM/PFA, the Walker Art Center, and Franklin Furnace, that includes 12 other international museums and arts organizations. CIAO develops standardized methods of documenting and providing access to conceptual and other ephemeral intermedia art forms. Another example of related work conducted by the project's partners is the Variable Media Initiative, organized by the Guggenheim Museum, which encourages artists to define their work independently from medium so that the work can be translated once its current medium is obsolete. Archiving the Avant Garde will take the ideas developed in previous efforts and develop them into community-wide working strategies by testing them on specific works of art in the practical working environments of museums and arts organizations. The final project report will outline a comprehensive strategy and model for documenting and preserving variable media works, based on case studies to illustrate practical examples, but always emphasizing the generalized strategy behind the rule. This report will be informed by specific and practical institutional practice, but we believe that the ultimate model developed by the project should be based on international standards independent of any one organization's practice, thus making it adaptable to many organizations. Dissemination of the report, discussed in detail below, will be ongoing and widespread.
Critical Arguements
CA "Works of variable media art, such as performance, installation, conceptual, and digital art, represent some of the most compelling and significant artistic creation of our time. These works are key to understanding contemporary art practice and scholarship, but because of their ephemeral, technical, multimedia, or otherwise variable natures, they also present significant obstacles to accurate documentation, access, and preservation. The works were in many cases created to challenge traditional methods of art description and preservation, but now, lacking such description, they often comprise the more obscure aspects of institutional collections, virtually inaccessible to present day researchers. Without strategies for cataloging and preservation, many of these vital works will eventually be lost to art history. Description of and access to art collections promote new scholarship and artistic production. By developing ways to catalog and preserve these collections, we will both provide current and future generations the opportunity to learn from and be inspired by the works and ensure the perpetuation and accuracy of art historical records. It is to achieve these goals that we are initiating the consortium project Archiving the Avant Garde: Documenting and Preserving Variable Media Art."
Conclusions
RQ "Archiving the Avant Garde will take a practical approach to solving problems in order to ensure the feasibility and success of the project. This project will focus on key issues previously identified by the partners and will leave other parts of the puzzle to be solved by other initiatives and projects in regular communication with this group. For instance, this project realizes that the arts community will need to develop software tools which enable collections care professionals to implement the necessary new description and metadata standards, but does not attempt to develop such tools in the context of this project. Rather, such tools are already being developed by a separate project under MOAC. Archiving the Avant Garde will share information with that project and benefit from that work. Similarly, the prospect of developing full-fledged software emulators is one best solved by a team of computer scientists, who will work closely with members of the proposed project to cross-fertilize methods and share results. Importantly, while this project is focused on immediate goals, the overall collaboration between the partner organizations and their various initiatives will be significant in bringing together the computer science, arts, standards, and museum communities in an open-source project model to maximize collective efforts and see that the benefits extend far and wide."
SOW
DC "We propose a collaborative project that will begin to establish such professional best practice. The collaboration, consisting of the Berkeley Art Museum and Pacific Film Archive (BAM/PFA), the Solomon R. Guggenheim Museum, Rhizome.org, the Franklin Furnace Archive, and the Cleveland Performance Art Festival and Archive, will have national impact due to the urgent and universal nature of the problem for contemporary art institutions, the practicality and adaptability of the model developed by this group, and the significant expertise that this nationwide consortium will bring to bear in the area of documenting and preserving variable media art." ... "We believe that a model informed by and tested in such diverse settings, with broad public and professional input (described below), will be highly adaptable." ..."Partners also represent a geographic and national spread, from East Coast to Midwest to West Coast. This coverage ensures that a wide segment of the professional community and public will have opportunities to participate in public forums, hosted at partner institutions during the course of the project, intended to gather an even broader cross-section of ideas and feedback than is represented by the partners." ... "The management plan for this project will be highly decentralized ensuring that no one person or institution will unduly influence the model strategy for preserving variable media art and thereby reduce its adaptability."
CA Discussion of the challenges faced by librarians and archivists who must determine which and how much of the mass amounts of digitally recorded sound materials to preserve. Identifies various types of digital sound formats and the varying standards to which they are created. Specific challenges discussed include copyright issues; technologies and platforms; digitization and preservation; and metadata and other standards.
Conclusions
RQ "Whether between record companies and archives or with others, some type of collaborative approach to audio preservation will be necessary if significant numbers of audio recordings at risk are to be preserved for posterity. ... One particular risk of preservation programs now is redundancy. ... Inadequate cataloging is a serious impediment to preservation efforts. ... It would be useful to archives, and possibly to intellectual property holders as well, if archives could use existing industry data for the bibliographic control of published recordings and detailed listings of the music recorded on each disc or tape. ... Greater collaboration between libraries and the sound recording industry could result in more comprehensive catalogs that document recording sessions with greater specificity. With access to detailed and authoritative information about the universe of published sound recordings, libraries could devote more resources to surveying their unpublished holdings and collaborate on the construction of a preservation registry to help reduce preservation redundancy. ... Many archivists believe that adequate funding for preservation will not be forthcoming unless and until the recordings preserved can be heard more easily by the public. ... If audio recordings that do not have mass appeal are to be preserved, that responsibility will probably fall to libraries and archives. Within a partnership between archives and intellectual property owners, archives might assume responsibility for preserving less commercial music in return for the ability to share files of preserved historical recordings."
This document provides some background on preservation metadata for those interested in digital preservation. It first attempts to explain why preservation metadata is seen as an essential part of most digital preservation strategies. It then gives a broad overview of the functional and information models defined in the Reference Model for an Open Archival Information System (OAIS) and describes the main elements of the Cedars outline preservation metadata specification. The next sections take a brief look at related metadata initiatives, make some recommendations for future work and comment on cost issues. At the end there are some brief recommendations for collecting institutions and the creators of digital content followed by some suggestions for further reading.
Critical Arguements
CA "This document is intended to provide a brief introduction to current preservation metadata developments and introduce the outline metadata specifications produced by the Cedars project. It is aimed in particular at those who may have responsibility for digital preservation in the UK further and higher education community, e.g. senior staff in research libraries and computing services. It should also be useful for those undertaking digital content creation (digitisation) initiatives, although it should be noted that specific guidance on this is available elsewhere. The guide may also be of interest to other kinds of organisations that have an interest in the long-term management of digital resources, e.g. publishers, archivists and records managers, broadcasters, etc. This document aimes to provide: A rationale for the creation and maintenance of preservation metadata to support digital preservation strategies, e.g. migration or emulation; An introduction to the concepts and terminology used in the influential ISO Reference Model for an Open Archival Information System (OAIS); Brief information on the Cedars outline preservation metadata specification and the outcomes of some related metadata initiatives; Some notes on the cost implications of preservation metadata and how these might be reduced.
Conclusions
RQ "In June 2000, a group of archivists, computer scientists and metadata experts met in the Netherlands to discuss metadata developments related to recordkeeping and the long-term preservation of archives. One of the key conclusions made at this working meeting was that the recordkeeping metadata communities should attempt to co-operate more with other metatdata initiatives. The meeting also suggested research into the contexts of creation and use, e.g. identifying factors that might encourage or discourage creators form meeting recordkeeping metadata requirements. This kind of research would also be useful for wider preservation metadata developments. One outcome of this meeting was the setting up of an Archiving Metadata Forum (AMF) to form the focus of future developments." ... "Future work on preservation metadata will need to focus on several key issues. Firstly, there is an urgent need for more practical experience of undertaking digital preservation strategies. Until now, many preservation metadata initiatives have largely been based on theoretical considerations or high-level models like the OAIS. This is not in itself a bad thing, but it is now time to begin to build metadata into the design of working systems that can test the viability of digital preservation strategies in a variety of contexts. This process has already begun in initiatives like the Victorian Electronic Records Stategy and the San Diego Supercomputer Center's 'self-validating knowledge-based archives'. A second need is for increased co-operation between the many metadata initiatives that have an interest in digital preservation. This may include the comparison and harmonisation of various metadata specifications, where this is possible. The OCLC/LG working group is an example of how this has been taken forward whitin a particular domain. There is a need for additional co-operation with recordkeeping metadata specialists, computing scientists and others in the metadata research community. Thirdly, there is a need for more detailed research into how metadata will interact with different formats, preservation strategies and communities of users. This may include some analysis of what metadata could be automatically extracted as part of the ingest process, an investigation of the role of content creators in metadata provision, and the production of user requirements." ... "Also, thought should be given to the development of metadata standards that will permit the easy exchange of preservation metadata (and information packages) between repositories." ... "As well as ensuring that digital repositories are able to facilitate the automatic capture of metadata, some thought should also be given to how best digital repositories could deal with any metadata that might already exist."
SOW
DC "Funded by JISC (the Joint Information Systems Committee of the UK higher education funding councils), as part of its Electronic Libraries (eLib) Programme, Cedars was the only project in the programme to focus on digital preservation." ... "In the digitial library domain, the development of a recommendation on preservation metadata is being co-ordinated by a working group supported by OCLC and the RLG. The membership of the working group is international, and inlcudes key individuals who were involved in the development of the Cedars, NEDLIB and NLA metadata specifications."
CA The metadata necessary for successful management and use of digital objects is both more extensive than and different from the metadata used for managing collections of printed works and other physical materials. Without structural metadata, the page image or text files comprising the digital work are of little use, and without technical metadata regarding the digitization process, scholars may be unsure of how accurate a reflection of the original the digital version provides. For internal management purposes, a library must have access to appropriate technical metadata in order to periodically refresh and migrate the data, ensuring the durability of valuable resources.

Descriptive Metadata Guidelines for RLG Cultural Materials
To ensure that the digital collections submitted to RLG Cultural Materials can be discovered and understood, RLG has compiled these Descriptive Metadata Guidelines for contributors. While these guidelines reflect the needs of one particular service, they also represent a case study in information sharing across community and national boundaries. RLG Cultural Materials engages a wide range of contributors with different local practices and institutional priorities. Since it is impossible to find -- and impractical to impose -- one universally applicable standard as a submission format, RLG encourages contributors to follow the suite of standards applicable to their particular community (p.1).
Critical Arguements
CA "These guidelines . . . do not set a new standard for metadata submission, but rather support a baseline that can be met by any number of strategies, enabling participating institutions to leverage their local descriptions. These guidelines also highlight the types of metadata that enhance functionality for RLG Cultural Materials. After a contributor submits a collection, RLG maps that description into the RLG Cultural Materials database using the RLG Cultural Materials data model. This ensures that metadata from the various participant communities is integrated for efficient searching and retrieval" (p.1).

Metadata Resources: Metadata Encoding and Transmission Standard (METS)
DC OAIS emerged out of an initiative spearheaded by NASA's Consultative Committee for Space Data Systems. It has been shaped and promoted by the RLG and OCLC. Several international projects have played key roles in shaping the OAIS model and adapting it for use in libraries, archives and research repositories. OAIS-modeled repositories include the CEDARS Project, Harvard's Digital Repository, Koninklijke Bibliotheek (KB), the Library of Congress' Archival Information Package for audiovisual materials, MIT's D-Space, OCLC's Digital Archive and TERM: the Texas Email Repository Model.
Museums and the Online Archive of California (MOAC) builds on existing standards and their implementation guidelines provided by the Online Archive of California (OAC) and its parent organization, the California Digital Library (CDL). Setting project standards for MOAC consisted of interpreting existing OAC/CDL documents and adapting them to the projects specific needs, while at the same time maintaining compliance with OAC/CDL guidelines. The present overview over the MOAC technical standards references both the OAC/CDL umbrella document and the MOAC implementation / adaptation document at the beginning of each section, as well as related resources which provide more detail on project specifications.
Critical Arguements
CA The project implements specifications for digital image production, as well as three interlocking file exchange formats for delivering collections, digital images and their respective metadata. Encoded Archival Description (EAD) XML describes the hierarchy of a collection down to the item-level and traditionally serves for discovering both the collection and the individual items within it. For viewing multiple images associated with a single object record, MOAC utilizes Making of America 2 (MOA2) XML. MOA2 makes the images representing an item available to the viewer through a navigable table of contents; the display mimics the behavior of the analog item by e.g. allowing end-users to browse through the pages of an artist's book. Through the further extension of MOA2 with Text Encoding Initiative (TEI) Lite XML, not only does every single page of the book display in its correct order, but a transcription of its textual content also accompanies the digital images.
Conclusions
RQ "These two instances of fairly significant changes in the project's specifications may serve as a gentle reminder that despite its solid foundation in standards, the MOAC information architecture will continue to face the challenge of an ever-changing technical environment."
