ARCFile Registry - Overview

The ARCFile Registry is an administrative OAI-PMH Repository, which keeps track of the creation and location of ARCFiles

• Register: Processed ARCfiles are registered using the Protocol for Metadata Posting (PMP).
• Retrieve: OAI-PMH is used to list and get ARCfiles contained in archive.

The resulting OAI Record contains the following information:

• ARCfile ID: Globally unique identifier, expressed as a URI, for the ARC file
• ARCfile File: Location of the ARC file
• ARCfile Index: Location of the index associated with the ARC file
• ARCfile Resolver OpenURL: BaseURL of the OpenURL Resolver that provides access to datastreams of all registered ARC files
• ARCfile Admin: Metadata from the version-1-block section of the ARC file
