The PIRUS2 (Publisher and Insitutional Repository Usage Statistics) project – which I blogged about briefly in September and which is exploring technical, organisational and economic issues in collecting and aggregating article usage statistics from repositories and publishers – has now been underway for a few months.
The project plan is available from the JISC Web site, with further information available from the project Web site. The primary partners in this project are MIMAS, Cranfield University, COUNTER, CrossRef and Oxford University Press – which means that it is well placed to consider the many issues to which the collection, aggregation and use of article level statistics gives rise.
PIRUS2 is not alone in considering these issues and is in contact with the Open Access Statistik and SURFSure projects in Germany and the Netherlands respectively which are also working on collecting article level usage data from repositories. The projects are taking similar technical approaches. One key decision – which is in line with a recommendation of the JISC usage statistics review of 2008 – has been to format log data as OpenURL context objects. One explanation of OpenURL context objects can be found on the SURF Web site. Other standards being used are OAI-PMH and SUSHI for harvesting the usage data.
PIRUS2 continues to the end of 2010.
