The OAI-PMH has become the de-facto standard for exposing metadata. In the PRESERV project we have explored new models for enabling thedigital preservation of and long-term access to content in Institutional Repositories (IRs). We envision digital preservation being achieved through simple preservation services working with standards-based, interoperable repository software. As support for the OAI-PMH matures so repositories are providing more robust mechanisms to access their content through OAI, e.g. community standards for using Dublin Core, support for METS or DIDL. Based on this, we have developed an exemplar File Format Profiling tool in the Registry of Open Access Repositories (ROAR), utilizing OAI and PRONOM DROID. PRONOM-ROAR is a first step to preserving digital content through simplifying content file format management for IR Managers by providing file format profiles and alerts
