LOTAR “Metadata for Archival Package” Workgroup

Goals and Objectives

The objective of the “Metadata for Archival Package” Working Group is to develop, publish and maintain a standard for Metadata for Archive Packages in a neutral form that can be read and reused independently of changes in the IT application environment originally used for creation.
The specific goal of the “Metadata for AP” Working Group is to define the principles, processes, information standards and quality criteria for metadata associated with the various information packages identified in the OAIS standard.
Based on the OAIS archive data process, the picture belows identifies the main Archival Packages to be specified in the Aerospace and Defence industry:

  • Submission Information Package (SIP)
  • Archival Information Packages (AIP)
  • Dissemination Information Package (DIP)

Associated LOTAR use cases


The LOTAR standards of the family 01X will answer to the following use cases (in development)

Long Term Archiving and Retrieval of Meta data for Archival Packages

2015?

Associated ISO 10303 referenced Information model

  • The LOTAR standards do not define specific information models for Long Term preservation. The working Group recommends the use of the ISO 10303 Application Protocols, based on the modular architecture, which ensures the consistency of the information models subsets, common to several ISO 10303 parts.
  • In this perspective, the LOTAR standard 01X will be based on the ISO 10303 STEP AP 239 “Product Life Cycle Support” (PLCS) standard and will rely on a STEP AP239 guidelines for implementation:
    • A common core set of meta data
    • Other extensions for particular use cases

Planning

Way of working – meetings and teleconferences

  • The “Metadata for Archive Package” Working Group holds biweekly WebEx/Teleconf meetings on Thursday s from 16H00 – 17H00 (European Central Time)

Accomplishments

  • Identification of initial business requirements, and start of the state of the arts.
  • Coordination set up with the LOTAR PDM working group.
