Opening up materials means that research data, methods, and publications are made freely available.
	- Open access to project materials promotes their further use. Open materials also bring visibility and merit to their creators.
- Research publishers and funders increasingly require that the background materials of a study be made as openly available as possible, at the latest upon completion of the study.
- For justified reasons, materials may have varying degrees of openness, ranging from completely open to confidential.
- When it comes to opening up research data, it is good to follow the principle of the Horizon 2020 Open Research Data pilot: "As open as possible, as closed as necessary."
