^bClarification of some professional roles is as follows: “executive leadership” refers to someone at the commissioner or C-level, “data owner” refers to someone with expertise on and administrative authority over a specific health dataset and with authority to release it to an open data platform, and “data expert” refers to someone understood by his/her peers to be a key contact and authority on the organization’s health data assets. Individuals may have had multiple roles, so this reflects the role most relevant to the interviews.

^cThere are more participants than interviews because some interviews had multiple participants.
