Purpose and Scope: The purpose of this dictionary is to describe the metadata used to support digital object storage in and presentation from the NDLP Repository. This metadata, or information about data, is referred to as Structural Metadata.
At least two other forms of metadata may be associated with objects stored in a digital repository. The first, Intellectual Metadata, describes the subject or intellectual content of the digital object. Intellectual Metadata is most commonly represented by the information found in bibliographic cataloging records or finding aids. The second, Access Control Metadata, refers to information related to the terms and conditions under which a digital object can be used, the identity of the copyright holder and any permissions for use granted by that copyright holder.
The primary focus of this dictionary is on the Structural Metadata. Intellectual Metadata is outside the scope of the digital repository and, hence, this section. Access Control Metadata will be addressed, but will be a secondary focus.
Dictionary Format: This dictionary is divided into three main sections. The first lists the attributes associated with digital objects for different types of material; initially photographs, images of text document pages, and SGML encoded documents. The second defines each of the attributes listed in the earlier section. The third is a general glossary of terms related to the digital repository and the electronic environment in which it will reside.
Please note that this dictionary is a work in progress. For changes since the last major revision, go to Change List.
