*** Apologies for cross-posting! *** Dear Colleagues, the Open Access Repository Ranking (OARR) was launched September 9, 2014 during the Open-Access-Tage conference.[1] It is the idea and goal of OARR to show best practices and role models of the German repository landscape so that other repository operators can learn from them and improve their services step by step. OARR is a research project based at the Information Management Department of Professor Peter Schirmbacher at the Berlin School of Library and Information Science (BSLIS), Humboldt-Universität zu Berlin (HU Berlin) and currently lists 152 open access publication repositories from Germany according to an open metric. Open metric means: - all criteria and scores are transparent; - the metric is developed together with the open access community to improve OARR.[2] Most of the criteria of the metric are derived from the “2014 Census of Open Access Repositories in Germany, Austria and Switzerland.” We encourage all repository managers, repository software developers and repository funders to contribute their ideas to the draft of the 2015 OARR metric using the UserVoice tool (in the “Contribute tab).[3] The ranking is planned to be published annually at the Open-Access-Tage conference in September. The preceding January each open access repository that meets the OARR definition will be contacted to submit their data via an online form.[4] For now OARR is a ranking limited to Germany. We are planning to make it a global ranking as soon as possible. However, this depends very much on the feedback of professionals from as many countries as possible to make the OARR metric a reliable and truly bottom up global benchmark for open access repositories. It is not clear yet whether the ranking should grow country by country or right to global scale but we are open for your ideas. We appreciate your questions, comments and feedback. All the best from Berlin, Germany Dennis on behalf of the OARR team [1] http://repositoryranking.org [2] http://repositoryranking.org/?page_id=660 [3] http://repositoryranking.org/?page_id=660 [4] http://repositoryranking.org/?page_id=1086 https://twitter.com/OARR_org -- Dennis Zielke Humboldt-Universität zu Berlin Arbeitsgruppe Elektronisches Publizieren am Computer- und Medienservice (CMS) Rudower Chaussee 26 D - 12489 Berlin Postadresse: Unter den Linden 6 D-10099 Berlin Tel. +49(0)30 2093-70004 Project LAUDATIO http://www.laudatio-repository.org/
