News from the Digital Library

The Metadata Encoding and Transmission Standard; the Open Archival Information System

Merrilee Proffitt

e(X)literature / Digital Cultures Project

April 2003


A telling example

A Telling Example


Goals of the digital library

Goals of the Digital Library

  • Collection

  • Access

  • Preservation


Problems with digital preservation

Unlike books (or papyrus) “bits …. don’t do well with benign neglect”

Problems with digital preservation


Open archival information system reference model

Open Archival Information System Reference Model

  • Framework for understanding and applying concepts needed for long-term preservation of digital information

  • Model targeted to several categories of user

  • Already widely adopted as starting point in digital preservation efforts


News from the digital library

OAIS Functional Entities

SIP = Submission Information Package

AIP = Archival Information Package

DIP = Dissemination Information Package


Information package variants

Information Package Variants

  • Submission Information Package

    • Negotiated between Producer and OAIS

    • Sent to OAIS by a Producer

  • Archival Information Package

    • Information Package used for preservation

    • Includes complete set of Preservation Description Information for the Content Information

  • Dissemination Information Package

    • Includes part or all of one or more Archival Information Packages

    • Sent to a Consumer by the OAIS


Relevance of the oais

Relevance of the OAIS

  • Offers common ground for discussion

    • Provides common terminology and concepts

  • Conceptual framework for building repository systems for digital content

  • Two components of Reference model

    • Functional model

    • Information model: model for packages of information


Digital library objects

Reformatted to digital

“Born digital”

Simple

Complex

Digital (Library) Objects

Digital Library Objects can be…


Structural metadata

Structural metadata

  • Maps physical files (digital assets) to logical items (complex digital objects)

    • Scanned print material

    • A/V material

    • Multimedia presentations


Other metadata

Other Metadata

  • All types of digital objects have other (non-structural) metadata

    • descriptive

      • MARC, Dublin Core, etc.

    • administrative

      • rights

    • technical

      • format details

    • Standards exist or emerging for these


Mets scope

METS Scope

  • Supports

    • Structural metadata

      • complex reformatted or born digital objects

    • Metadata wrapper framework

      • descriptive, administrative, structural, etc.

      • structural required

      • others use namespaces to reference “extension schemas”


Mets scope1

METS Scope

  • Data transfer syntax

    • between applications

    • between institutions

  • Driver for applications

    • page turner

    • audio player

    • multimedia presentation


Mets history

METS History

  • Making Of America II project 1997-2000

  • METS “born” February 2001

  • METS 1.0 July 2002

  • Current version is METS 1.2

Mets and oais framework

METS and OAIS framework

  • Submission Information Package (SIP)

    • METS as transfer syntax

  • Dissemination Information Package (DIP)

    • METS as transfer syntax

    • METS as input to display applications

  • Archival Information Package (AIP)

    • METS stored internally in an archive


  • Mets initiative

    METS Initiative

    • Establishment of an editorial board with an editor-in-chief

    • Complete work on schema, ensure support for other digital library work

    • Encourage field testing of METS and gather feedback

    • Encourage tools development

    • Identification of “best practice” extension schemas

    Mets summary

    METS summary

    • Closely related to OAIS information package

    • Large and growing community of digital library implementers

    • Very flexible

    • Flexibility means that profiles are necessary for interoperability
