4.2.1 - The repository shall have for each AIP or class of AIPs preserved by the repository an associated definition that is adequate for parsing the AIP and fit for long-term preservation needs.

Introduction
SP's Definition of AIPs explains the different components that make up an AIP within the repository. SP's ejournal AIPs are all fairly similar in composition and are therefore treated in a consistent manner.

  • SP stores the Content Data Object separately from the preservation metadata file. The CDO is stored on a filesystem with a reference to its location contained in the preservation metadata.
  • The Representation Information, Preservation Description Information (PDI), Packaging Information and Descriptive Information of the content object are all contained within a metadata scheme based on METS (Metadata Encoding and Transmission Specification). Within this container, SP uses the PREMIS (Preservation Metadata Implementation Strategy) vocabulary. The repository makes use of the objects, events and rights entities described in the PREMIS Data Model. In the case of journals, Scholars Portal uses the NLM Journal Archiving & Interchange Tag Set to structure descriptive metadata. Scholars Portal normalizes the descriptive metadata and structural relationships submitted by Providers to version 3.0 of the NIH Journal Archiving & Interchange Tag Set.
