The #EuropeanCommission is finally considering whether "#OpenSource software (#OSS)…can be used as a foundation for developing the new #publishing platform" for EC-funded #OpenAccess research.

Unfortunately, the new software would merely "underpin" #OpenResearchEurope (#ORE), not replace it. ORE is proprietary software owned by #TaylorAndFrancis. When the EC called for bids on ORE, it did not require open code despite many calls to do so.

Analysis of the requirements for the Open Source infrastructure of the Open Research Europe Publishing Platform.

Open Research Europe (ORE) is the peer-reviewed open-access publishing platform of the European Commission. It follows the post-publication peer review model to promote scientific transparency and reuse.

Update. The #EuropeanCouncil just adopted the #OpenScience proposal anticipated earlier this month (this thread, above). No #embargoes. No #APCs. #Nonprofit publishing. #OpenLicenses. #OpenInfrastructure. https://www.consilium.europa.eu/en/press/press-releases/2023/05/23/council-calls-for-transparent-equitable-and-open-access-to-scholarly-publications/

While this is not yet policy, it's a weighty recommendation to the Commission and member states.
