Item identifiers play an important role in allowing IRUS to produce accurate statistics and to interoperate with other services. We have produced a brief document outlining our recommended methods of cataloguing several key identifiers and how they should be exposed in repository OAI interfaces.

Pure metadata for datasets
Pure, unlike all other repository software, does not expose bibliographic metadata for datasets via OAI-PMH, which is our preferred source of metadata. This means that we need to use an alternative method to retrieve dataset metadata (such as titles, authors, dataset identifiers, etc.) from Pure repositories. Consequently, we request access to the repository's Pure API - solely for the purpose of retrieving dataset metadata - which requires that the repository supplies us with a valid API key to enable that access.
