DRS Documentation/DRS Glossary

administrative metadata

Administrative metadata is information stored and used to manage a digital object. The DRS uses administrative metadata to record who has the right to view an object or what changes have been made to an object over time.

API

An API (application programming interface) is a set of specifications used to instruct technologies on how to interact with each other. Fedora, the architectural foundation of the DRS, has an API that allows other programs and interfaces, like Wordpress or Omeka, to access or display files stored in the DRS.

Blacklight

Blacklight is discovery interface for the Solr index. The DRS uses Blacklight to create facets and limits for search results.

Central Authentication Service

Central Authentication Service (CAS) is a protocol that allows users to sign in to one service that authenticates many different applications. Northeastern University uses Shibboleth as its CAS, and the DRS uses Shibboleth to authenticate users for the DRS.

digital repository

A digital repository is a digital object storage solution that stores and maintains a broad range of materials from various sources.

Download Queue

A Download Queue is a temporary list of files in the DRS that can be downloaded as a compressed .zip file. Files added to your DRS Download Queue will remain in the queue until you sign out or close your browser.

DRS

The Digital Repository Service (DRS) is a secure digital repository system designed to store and share the scholarly work from Northeastern University’s colleges, departments, faculty, and staff.
