The functions and practices that result in published (and usable) beneficial ownership data.
Digital “structured” or “machine-readable” data that is “made available with the technical and legal characteristics necessary for it to be freely used, reused, and redistributed by anyone, anytime, anywhere.”
Beneficial ownership data is made available to any user with no access restrictions (e.g. registration, fees).

A beneficial ownership register can be publicly accessible without being available in open data format - for example, individual records could be searchable by the public, but the data cannot be downloaded in bulk as structured data. Thus, it is important to define both terms.
