Checked the home page it says "This approach encourages companies to continue to support data portability, knowing that their proprietary technologies are not threatened by data portability requirements. For a detailed taxonomy of such data, see ISO/IEC 19944:2017."
Went to look for ISO standart, and founs out thet it's status is "Withdrawn"
It's been revised and updated, yes, that means the document is withdrawn but the standard lives on in 19944-1:2020.
"This first edition of ISO/IEC 19944-1, along with ISO/IEC 19944-21 cancels and replaces ISO/IEC 19944:2017, which has been technically revised.
The main changes compared to the previous edition are as follows:
— provides additional material which principally deals with organizational data and the need to treat some organizational data in particular ways in order to ensure confidentiality, integrity and so on,
— the new concept of data facets is introduced and data facets are used to extend the expressiveness of data use statements, including adding the concept of which individuals or organizations have control over data,
— the new data use categories are introduced, including some that address the newer uses of data associated with artificial intelligence systems.
A list of all parts in the ISO/IEC 19944 series can be found on the ISO website."
