Amends the Government Data Collection and Dissemination Practices Act (§ 2.2-3800 et seq.) to facilitate the sharing of data among agencies of the Commonwealth and between the Commonwealth and political subdivisions. The bill creates the position of Chief Data Officer of the Commonwealth (CDO), housed in the office of the Secretary of Administration, to (i) develop guidelines regarding data usage, storage, and privacy and (ii) coordinate and oversee data sharing in the Commonwealth to promote the usage of data in improving the delivery of services. The bill also creates a temporary Data Sharing and Analytics Advisory Committee (Advisory Committee) to advise the CDO in the initial establishment guidelines and best practices, and to make recommendations to the Governor and General Assembly regarding a permanent data governance structure.
