Identifier Locator - Overview

A fast, in-memory MySQL-based solution used for efficient storage and resolution of Datastream, Content, and Surrogate Identifiers to Repository Identifiers. Designed to store more than 1 Billion identifiers with sub-10ms retrieval times. An OpenURL service interface is provided for the web service based resolution.

• Stores all identifiers of aDORe repositories (DIDLDocumentIdentifier, digital object identifier, datastream identifier)
• Loaded by retrieving identifiers from aDORe repositories using their openurl-aDORe3 service interface
• Identifier Locator identifier: info:lanl-repo/idlocator
• Stores [identifier, repository identifier, ingestion date]
• 1 core service interface to Identifier Locator:
  • openurl-aDORe2
    • retrieve a list of all the locations (repositories in aDORe) containing a specified identifier
    • service identifier: info:lanl-repo/int/idlocator/openurl-aDORe2
