National repository and portal for open science

Since June 2020 there is a National repository for open access to scientific information (https://bpos.bg/en/publish ). It is a cross-disciplinary repository administrated by NACID (https://nacid.bg/en/ ) for scientific publications that are result from publicly funded research. It is developed in compliance with the OpenAIRE Guidelines for Literature Repository Managers v.4.

Since June 2020 there is also a fully functional Bulgarian Portal for Open Science (BPOS https://bpos.bg/ ), maintained by NACID.  The portal and the repository form a system that provides researchers and the public at large with access to scientific publications and other research outputs free of charge in an open and non-discriminatory manner. The system enables the dissemination and enables the use and re-use of scientific research results, thus minimizing efforts and maximizing the benefits of the research.

BPOS and the repository are constantly improving, expanding and striving to transform the way research is conducted. Series of events, workshops and trainings is being carried out with the participation of researchers from Bulgarian RPOs. NACID and MES are working together to engage stakeholders as much as possible in the initiative for open access to scientific information.

Strategic framework:

  • National Open Science Plan, January 2021 – the main strategic document with regards to open science that outlines the open science vision of Bulgaria, gives an overview of reached milestones and takes them into account and outlines detailed objectives, commitments and action points with regard to the development and sustainability of the open science initiative in Bulgaria for the next five years.
  • National strategy for the development of the scientific research 2017 – 2030 + Implementation plan – “open access to scientific information” is a strategic action point and also there is an objective “active participation in the European research area and strengthening international cooperation and partnerships in the field of science, including the EOSC and similar initiatives.”
  • National concept for open access to scientific information - outlines the essence and framework of open science.
  • Guidelines on sharing scientific publications with open access and using the national repository and the portal for open science are published in the Bulgarian Portal for Open Science (BPOS) and are distributed within the research community.
