Data strategy and governance

What data do we need, and who is responsible for it?

Every term below is defined in the words of data strategy and governance, guide R14 of craft guides for educational technologists, and opens the guide at the slide where it is taught. 25 of the 50 are the field’s vocabulary rather than the guide’s own: words a reader will meet around this subject, defined here because the guide assumes them. 1 term is also defined by another guide in the series; where the two differ, both wordings are given. The whole craft glossary holds all of them together.
