• Retrieve: OAI-PMH is used to list and get XMLtapes contained in archive.

The resulting OAI Record contains the following information:

• XMLtape ID: Globally unique identifier, expressed as a URI, for the XMLtape
• XMLtape File: Location of the XMLtape file.
• XMLtape Index: Location of the index associated with the XMLtape file
• XMLtape Index Plugin: Absolute classpath of interface used to write and read the index associated with the XMLtape file
• XMLtape OAI-PMH URL: BaseURL to XMLtape registered in the XMLtape Registry
• XMLtape OAI-PMH Properties: Pointer to a configuration file that expresses specific OAI-PMH properties of the OAI-PMH interface to the XMLtape
• XMLtape Admin: Tape-admin information copied from the header of the XMLtape
