Scholars Portal Metadata Specifications

1. Policy Statement

o Scholars Portal requires thorough, well-structured metadata in order to preserve the content, relationships, activities and logical structural of the content object.

2. Implementation

o Scholars Portal uses a structural metadata scheme based on a simplified METS (Metadata Encoding and Transmission Specification) as a robust and flexible way to structurally define the content object. It serves as a container for all of the metadata about the object.

o Within this container, Scholars Portal uses the PREMIS (Preservation Metadata Implementation Strategy) vocabulary. PREMIS’s data dictionary provides ways of describing objects and processes that are necessary for digital preservation. Scholars Portal makes use of the objects, events and rights entities described in the PREMIS Data Model.

o In the case of journals, Scholars Portal uses the NIH Journal & Archive Tag Set to provide descriptive metadata. Scholars Portal normalizes the publisher provided descriptive metadata and structural relationships to version 3.0 of the NIH Journal Archiving & Interchange Tag set.
“The intent of the Archiving Tag Set is to preserve the intellectual content of journals independent of the form in which that content was originally delivered. This Tag Set enables an archive to capture structural and semantic components of existing material without modeling any particular sequence or textual format”. 1
