From the COAR (Conferedation of Open Access Repositories) Website:
Over the last year, as part of the Aligning Repository Networks activities, COAR has been continuing to work on facilitating communication and greater interoperability of the major repository networks. Key events included a high-level meeting of senior representatives from around the world in Portugal in April 2015, a meeting between OpenAIRE, SHARE and LA Referencia in the US in July, and most recently a joint workshop between COAR, OpenAIRE, and LA Referencia Council in Rio de Janeiro focusing on greater interoperability between Latin American and European repositories. This report summarizes activities over the past year and emphasizes the importance of ongoing conversations. This aligning work is partially funded by the European Commission through the OpenAIRE2020 project.
