The EOSC Association is the legal entity established to govern the European Open Science Cloud (EOSC). It was formed on 29th July 2020 with four founding members and has since grown to over 200 Members and Observers. The Association membership is jointly responsible for delivering the objectives agreed in the Memorandum of Understanding signed by the European Union and EOSC Association to form the official Partnership. The EOSC ecosystem is being co-created in a series of funded projects and initiatives from Member States and Associated Countries. The EOSC Association plays an important role in helping to coordinate and steer these investments via its Task Forces and other governance structures.
