Episciences: enhancing interoperability and metadata between an overlay journal platform, linked repositories and OpenAIRE open sciences tools and services

Episciences is a platform to publish diamond open access overlay journals. Episciences contributes to the development of bibliodiversity by supporting an alternative path to the conventional model of scientific publication, promotes the usage of preprints and the collaboration with open repositories. The editorial process is based on a convergence of the stages of qualification, certification and dissemination and a system for recording the different versions of a document—the preprint reviewed, revised, accepted for publication, the new version, the published article are all "record of version". Thus the value chain is no longer limited to the only reference version which is the published article—"version of record"—endorsed by the journal. Designed as an overlay of services on top of open repositories, the platform makes by design an extensive usage of API and open protocols since its inception.
