VSAC Author Registration

What is a VSAC author, steward or group?

Authors and Stewards create, edit, and publish value sets in VSAC. Note that all VSAC users can search for published value sets and download them. These permissions only apply to users that need to create, edit, and publish value sets in VSAC.

See the VSAC author, steward, and group roles and permissions page for details about these roles.

Do you need to join an existing group?

Current group members can add you to the group. See the Group Management page for instructions.

Are you a brand new VSAC author or steward and need to create new groups?

These permissions only apply to users that need to create, edit, and publish value sets in VSAC.

If you plan to create value sets in VSAC with a colleague who already has VSAC authoring permissions, please do not submit this form. Instead, ask your colleague to add you to their VSAC author and/or VSAC steward groups. For more information, see the Group Management page. Otherwise please continue and submit this form.
