The PIRUS Code of Practice has been established as an outcome of the JISC- funded PIRUS (Publisher and Institutional Repository Usage Statistics) project, whose overall aim was to assess the feasibility of and develop the technical, organizational and economic models for the recording, reporting and consolidation of usage of Journal Articles hosted by Publishers, Aggregators, Institutional Repositories and Subject Repositories.
PIRUS is consistent with the COUNTER Code of Practice and COUNTER will be responsible for its development, ongoing management and implementation. This draft Release 1 of PIRUS Code of Practice will be available on the COUNTER website for public comment until 30 April 2013. Feedback received will be taken into account by the COUNTER Executive Committee in the preparation of the final, definitive version of Release 1, which will be published later in 2013. To have their usage statistics and reports designated PIRUS-compliant vendors and services will have to provide usage statistics that conform to this Code of Practice.
The PIRUS Code of Practice provides the specifications and tools that will allow COUNTER-compliant publishers, repositories and other organizations to record and report usage statistics at the individual article level that are credible, compatible and consistent.
