OPERAS is the Research Infrastructure dedicated to support open scholarly communication for the Social Sciences and the Humanities in the European Research Area (ERA). The OPERAS-PLUS project started on September 1, 2022, has a duration of 36 months and runs from September 2022 to July 2025 under Grand Agreement Number 101079608 (https://cordis.europa.eu/project/id/101079608). It receives funding from the Horizon Europe framework Infra-Dev in order to support new ESFRI research infrastructure projects in their preparatory phase . OPERAS was selected in 2021 as a new infrastructure on the ESFRI Roadmap for the excellence of its scientific case and for its strategic importance for the European Research Area and the structuring of the European research infrastructure ecosystem. OPERAS is now on its path to becoming operational as an ERIC in 2028.

The project aims at supporting this process and the development of the infrastructure in its preparatory phase and on its way towards implementation as an ERIC. It will empower OPERAS to further 

  • Strengthen its governance structure in regard to financial, legal and human resources
  • Support the network of national nodes and their national activities
  • Develop the services portfolio providing both required technology and a monitoring system for services development
  • Maximise OPERAS’ impact in the ERA and at the international level by extending it beyond its current scope and onboarding new members and countries in the infrastructure.

The body of work will stand in the continuity of work already realised in the former projects (OPERAS-D, OPERAS-P, HIRMEOS) and collaborate with the running projects COESO, TRIPLE, and DIAMAS, and soon with other projects to come in 2023.

Work packages and OPERAS-Plus Pillars

The methodological approach of OPERAS-PLUS is based on two Pillars:

(1) the establishment of the infrastructure through the support to the legal entity and

(2) the support and development to the OPERAS services and especially the building of its catalogue.
