Download data is being logged by every repository as a by-product of the Web requests they receive. This raw data is being and turned into useful download statistics for individual papers and users by a few institutional repositories (e.g. University of Tasmania, Southampton University), thematic repositories (e.g. RePEc) and OAI services (e.g. Citebase). However, there is no consensus over what data needs to be collected, what filtering mechanisms are appropriate, and what analyses are useful for academics in various disciplines. To create effective research statistics services, an interoperable usage statistics service will be created for all OAI-PMH-compliant repositories. This project will investigate the requirements for UK and international stakeholders and build generic collection and distribution software for all IRs. The approach will be demonstrated by a pilot statistics analysis service modelled as an OAI service provider. Working with partners experienced in analysis of usage statistics for electronic documents, and an international consultative committee of key OAI archive and service managers, the principal deliverables will be:
