“Open Access”, refers to the practice of providing online access to scientific information that is findable, interoperable, free of charge to the end-user, and reusable. 'Scientific' refers to all academic disciplines. In the context of research and innovation, 'scientific information' can mean:
• peer-reviewed scientific research articles (published in scholarly journals) or
• research data (data underlying publications, curated data and/or raw data).
The definition of OA has been evolving over time and it is heading towards a more robust Open Science concept.
