Describe what you would change to the page
I think we should add a paragraph to clearly explain the difference between "sharing data" and "open access data".
Sharing datasets:

• Does not necessarily mean Open Access nor Public. (Meta)Data can be shared with Closed or Restricted Access.
• Does not have to happen immediately, while you are still working on the project. Data can be shared after your scientific paper is published.
• Is different from sharing your “result paper”. Difference between "Open access publications" and data.
