I have a question about taxonomies.

Do they exist at only the site collection level? Or can you specify unique taxonomies at the sub-site level as well?

There are only two types of Term Groups:

  • Global Term Group. Managed via the central administration UI. Read-only access from all site collections and sites.
  • Site Collection Term Group. Managed on the site collection level. Read-only access can be granted to other site collections using "Site Collection Access" (in SharePoint Online Only).

Term Groups types

Subsite Term Group does not exist.


They exist in the central term store (MMS SA) and Site Collection (terms themselves are in the MMS SA, but the SA has a pointer to the specific Site Collection).

Subwebs do not have their own taxonomy stores.
