METS profile development

[edit] Background
The 2007 APSR/NLA METS Profile Development project is an APSR RIFF project (NLA RIFF P1) which aims to facilitate the adoption of the Metadata Encoding and Transmission Standard (METS) as a common format for exchanging data between repositories and other workflow environments.
[edit] What is METS?
METS is a standard for encoding descriptive, administrative and structural metadata for digital objects.
A METS package for a digital object contains information on:
- the structure of the object;
- names and locations of files that comprise the object; and
- metadata associated with the object (e.g., descriptive metadata utilising MODS as an extension schema, preservation metadata according to PREMIS, rights metadata through METS Rights).
[edit] What is a METS profile?
A METS profile describes a class of METS packages, specifying the requirements that packages conforming to the profile must satisfy.
METS profiles are intended to be human-readable, not machine-actionable.
[edit] Project summary
The objectives of the APSR/NLA METS Profile Development Project are to develop and document:
- a core generic METS profile for submission and exchange of digital objects; and
- implementation-specific METS sub-profiles for each of the APSR RIFF Workflow projects.
This work also informs the NLA Newspapers Digitisation Project.
The work of this current project is based on the 2006 APSR/NLA PRESTA project, which aimed to develop a requirements specification for preservation metadata for digital objects, based on the PREMIS (PREservation Metadata: Implementation Strategies) final report, the Data Dictionary for Preservation Metadata. An outcome of APSR/NLA PRESTA project was the PREMIS Requirement Statement Project Report, which included a draft profile for exchange of digital objects between repositories.
A new version of the profile has now been issued as the Australian METS Profile v. 0.2. This version will continue to be revised as the implementation-specific profiles are developed, based on input from the APSR Reference Groups. Once finalised, the core profile and the implementation-specific profiles will be registered with the Library of Congress.
Thinking about the profile has been facilitated by the diagram opposite, which expresses requirements for a conformant METS document in terms of:
- the elements and attributes that are required;
- the elements and attributes that aren’t allowed or are not used; and
- extension schema that might be used within particular elements.
[edit] Project meetings and workshops
A workshop to discuss the draft core profile was held at the National Library of Australia on 20 February 2007.
[edit] Content models
The core generic profile and the implementation-specific profiles will be informed by content models developed by each of the APSR RIFF Workflow Reference Groups and the NLA's Newspapers Digitisation Project.
