# Tags in Systems Central

Local use of Tags (mirror): optional shared labels on systems, decisions, work and feedback.

[Shared definition and source fields](/systems/core/tag).

Tags (mirror) is the shared classification catalog, synced one-way from Core. System, Feedback, Architecture Decision, Work Item and the three other mirrors link to it through optional Tags columns. A tag classifies. It does not create a task, change a status or grant access.

## Local usage

| Field | Type | Links to |
| --- | --- | --- |
| System | Linked records | [System](/systems/systems-central/entity-system) → Tags |
| Feedback | Linked records | [Feedback](/systems/systems-central/entity-feedback) → Tags |
| Architecture Decision | Linked records | [Architecture Decision](/systems/systems-central/entity-architecture-decision) → Tags |
| Work Items | Linked records | [Work Item](/systems/systems-central/entity-work-item) → Tags |
| Membership (mirror), Organization (mirror), Tool (mirror) | Linked records | Tags on each mirror |
| Tags / From field: Tags | Linked records | A local self-link pair on the catalog |

Name, Kind and notes come from Core. System Rule and Record Type have no Tags column yet; a Work Item asks for it. Per the table description, rows removed at the source are kept so local links survive. Review a retired label before reusing it.

## Maintenance

Add, rename or retire tags in Core, never here.
