OAIS and It's Applicability for Libraries, Archives, and Digital Repositories - Robin Dale (2001)

  1. 1. OAIS and It’s Applicability for Libraries, Archives, and Digital Repositories Robin Dale RLG [email_address]
  2. 2. Characteristics of Digital Information in Libraries and Archives <ul><li>Diversity </li></ul><ul><ul><li>of applications (commercial, “home-grown,” operational, etc.) </li></ul></ul><ul><ul><li>in the organization, structure and encoding of documents and data </li></ul></ul><ul><li>Complexity </li></ul><ul><ul><li>varies greatly </li></ul></ul><ul><li>Volume </li></ul><ul><ul><li>Previously low, but growing at exponential rates. </li></ul></ul>
  3. 3. Characteristics and Diversity of Information to be Archived <ul><li>Data file collections </li></ul><ul><li>Images </li></ul><ul><ul><li>JPEG, GIF, TIFF, PS formats </li></ul></ul><ul><li>Text documents </li></ul><ul><ul><li>PDF, TXT, HTML, XML formats </li></ul></ul><ul><li>Audio and video </li></ul><ul><ul><li>WAV, AIFF, MPEG, etc. </li></ul></ul><ul><li>Other data types </li></ul><ul><li>Links to other archives </li></ul>
  4. 4. The Difficulties of Preserving that Information <ul><li>Technical factors </li></ul><ul><ul><li>increasingly frequent technological changes </li></ul></ul><ul><ul><li>non-independence of archived information with regard to systems </li></ul></ul><ul><ul><li>control of migration process </li></ul></ul><ul><li>Organizational factors </li></ul><ul><ul><li>organizational change </li></ul></ul><ul><ul><li>priority shift in tandem with leadership shift </li></ul></ul><ul><li>Scientific factors </li></ul><ul><ul><li>the knowledge to interpret certain data/datatypes </li></ul></ul>
  5. 5. Open Archival Information System (OAIS) <ul><li>Open Archival Information System Reference Model </li></ul><ul><ul><li>Framework for understanding and applying concepts needed for long-term preservation of digital information </li></ul></ul><ul><ul><ul><li>Adaptation and development to fit certain information types (digital images, space systems data, etc.) left to those who adopt the model </li></ul></ul></ul><ul><ul><li>Facilitates description and comparison of archives (a common vocabulary of concepts) </li></ul></ul><ul><ul><li>Addresses a full range of archival functions </li></ul></ul><ul><ul><li>Basis for development of additional, related standards (OAIS Reference Model - April 2001 version - is a draft ISO standard) </li></ul></ul><ul><ul><li>Broad, international interest and work moving forward </li></ul></ul>
