Tag Manager, subjects, and people
Open Tag Manager from the activity rail or the Tags sidebar. It is a full workspace section with separate Tags, Subjects, and People tabs.
Scope
The root selector at the top controls the manager's catalogue and every exact name mutation performed inside it. Choose one root when equal tag or subject names exist in several databases. All roots is useful for inspection, but identity-sensitive operations may require an explicit root.
The file browser sidebar remains a merged browsing catalogue; leaving Tag Manager restores that global view. Changes made in scoped Tag Manager menus do not silently switch the manager back to the global catalogue.
Tags
Select a tag to inspect assignments and values. Depending on the tag, the manager can rename or delete it, move a hierarchy, change the hierarchy separator, manage value synonyms, promote a tag to a subject property, prune unused tags, and edit its property contract.
Separator changes use a guarded confirmation. Press Escape while the guard is armed to cancel it.
Subjects
Subjects group properties that belong to the same entity rather than directly
to a file. Subject names and pure hierarchy prefixes can be renamed in the
manager. Subject synonyms affect only subject: queries; they never broaden a
plain tag query with the same text.
Autocomplete in tag and subject editors replaces only the segment at the caret,
up to the next / or =. Existing suffixes are preserved, which makes editing
long hierarchical names predictable.
People
The People tab combines named face identities with their file assignments. Because identities are database-owned, select an explicit root before making changes when several roots are loaded. See Face recognition for detection and assignment workflows.
