When it comes to publishing your data, you have options with the level of access you give to your data:
Open access: research data is open and freely available to be accessed and re-used
Controlled or mediated access: the metadata of your research data is openly available; access to your research data is granted upon request
Restricted access: the metadata of your research data is openly available; no access is given to the research data
Embargoes: a specific date that you can apply to a dataset record to specify when the data can be released as open or mediated access. The embargo date could, for example, make the research data restricted until an associated research paper is published.
