E-Resources Preservation Webinar: Q&A
Questions submitted during the February 10, 2010 NISO webinar, "What It Takes To Make It Last: E-Resources Preservation," with presenters Priscilla Caplan (Assistant Director for Digital Library Services, Florida Center for Library Automation) and Jeremy York (Assistant Librarian, University of Michigan Library).

Standards for Digital Preservation

Reference Model for an Open Archival Information System (OAIS)
Prepared by the Consultative Committee for Space Data Systems (CCSDS), this document is "a technical Recommendation for use in developing a broader consensus on what is required for an archive to provide permanent, or indefinite long-term, preservation of digital information. This Recommendation establishes a common framework of terms and concepts which  comprise an Open Archival Information System (OAIS)."

PLANETS (Preservation and Long-term Access through Networked Services)
PLANETS is a "four-year project co-funded by the European Union under the Sixth Framework Programme to address core digital preservation challenges. The primary goal for Planets is to build practical services and tools to help ensure long-term access to our digital cultural and scientific assets."

PLATO (PLANETS Preservation Planning Tool)
Plato is "a decision support tool that implements a solid preservation planning process and integrates services for content characterisation, preservation action and automatic object comparison in a service-oriented architecture to provide maximum support for preservation planning endeavours."

Producer-Archive Interface Methodology Abstract Standard
Prepared by the Consultative Committee for Space Data Systems (CCSDS), the "purpose of this Recommendation is to identify, define and provide structure to the relationships and interactions between an information Producer and an Archive."

InterPARES Project
The InterPARES (The International Research on Permanent Authentic Records in Electronic Systems) Project "aims at developing the knowledge essential to the long-term preservation of authentic records created and/or maintained in digital form and providing the basis for standards, policies, strategies and plans of action capable of ensuring the longevity of such material and the ability of its users to trust its authenticity."

Trustworthy Repositories Audit and Certification (TRAC): Criteria and Checklist
Published by the National Archives and Records Administration (NARA). From the document: "Regardless of size or purpose, all repositories should be encouraged to use this checklist as a tool for objective evaluation whether it is accomplished in-house or by an objective, third-party auditor, and regardless of whether it is accomplished for local information gathering and evaluation or as a part of an international or national certification process."

DRAMBORA (Digital Repository Audit Method Based On Risk Assessment) Interactive
This online toolkit, from the Digital Curation Centre (DCC) and DigitalPreservationEurope (DPE), is "intended to facilitate internal audit by providing repository administrators with a means to assess their capabilities, identify their weaknesses, and recognise their strengths."


Packaging / Aggregation

Repository eXchange Package (RXP) Spec
"The Repository Exchange Package (RXP) is a hierarchical packaging format designed to facilitate the exchange of Archival Information Packages (AIPs) between digital repositories."

Framework of Guidance for Building Good Digital Collections
The 3rd edition (2007) of the Framework, published by NISO with support by the Insitute for Museum and Library Services (IMLS), is an online resource for open commenting and feedback. The Framework "provides an overview of some of the major components and activities involved in the creation of good digital collections and provides a framework for identifying, organizing, and applying existing knowledge and resources to support the development of sound local practices for creating and managing good digital collections. It is intended for two audiences: cultural heritage organizations planning projects to create digital collections, and funding organizations that want to encourage the development of good digital collections."

Evaluation of file formats

  • Selecting File Formats for Long-Term Preservation (The National Archives, UK)
  • Sustainability of Digital Formats website (Library of Congress)

Sustainable formats

  • Open Document Format (ODF) : OAISIS and ISO/IEC 26300:2006 Open Document Format for Office Applications (OpenDocument) v1.0.
  • PDF/A
  • SIARD (Software Independent Archiving of Relational Databases)
  • WARC : ISO 28500:2009, Information and documentation — WARC file format.

Format-specific technical metadata

  • Audio Engineering Society AES-X098 (draft)
  • Data Dictionary -Technical Metadata for Digital Still Images : ANSI / NISO Z39.87
  • MIX Metadata for Images in XML
  • TextMD Technical Metadata for Text

About XCL - eXtensible Characterization Language
From the site: "One of the goals of the preservation characterisation sub-project is to help develop a way to monitor whether a file format migration from format A to format B has fulfilled this condition. ...The Planets team of the Universität zu Köln (UzK) is developing ways to describe these file formats in a way to make the comparison of the information contained within files in different formats possible. This is done with two formal languages, called the Extensible Characterisation Definition Language (XCDL) and the Extensible Characterisation Extraction Language (XCEL), which describe formats and the information contained within individual files."

CRL Certification and Assessment of Digital Repositories
This Center for Research Libraries page is the home for information on a project initiated in 2009 to conduct "in-depth assessments of two repositories of interest to the CRL community: Portico and HathiTrust.  The purpose of these was to promote understanding of and, where justified, confidence in, digital repositories."

PRONOM Technical Registry
From the UK National Archives, PROMOM is an online registry of technical information that serves as a "resource for anyone requiring impartial and definitive information about the file formats, software products and other technical components required to support long-term access to electronic records and other digital objects of cultural, historical or business value."

Unified Digital Formats Registry (UDFR)
A registry to "support the requirements and use cases of the larger community compiled for GDFR [Global Digital Format Registry] and would be seeded with PRONOM's software and formats database."
