Summary

Add first-class Tag support across IDP views—Catalog, Scorecards, TechDocs, and Workflows—to filter, group, and segment entities and insights by customizable key:value tags (e.g., domain:payments, tier:critical, lifecycle:beta, language:go).

IDP impact: Tags help users quickly determine where to improve, invest, or deprecate within IDP.

Problem / Why Now

IDP users lack consistent, native slicing of catalog and adoption data by business/technical dimensions.

Scorecard and workflow views can’t be segmented to spotlight gaps or progress by domain, tier, or lifecycle.

Teams resort to naming conventions or spreadsheets, slowing IDP-driven decisions.

Goals & Outcomes

Faster decisions inside IDP: Filter/group IDP views by tag in 1–2 clicks.

Targeted adoption inside IDP: Track remediation and campaigns by tagged cohorts.

Clear governance signals: Apply standards per tag (e.g., tier:critical requires SLO + on-call) and see status in IDP.

Scope (IDP Only)

Key:value tags with optional org-level allowed keys.

Attach to IDP catalog entities: Component, API, Resource, System (optionally Domain/Group).

Optional inheritance (System → Components) with explicit overrides.

Global Tag Filter (multi-select chips) on Catalog, Scorecards, TechDocs, and Workflows.

Tag Badges on entity cards/details; click applies filter.

Saved Views: shareable presets that store tag filters (e.g., “Tier-1 Services”).

Group By Tag in scorecards and workflow analytics.

Bulk Tagging (RBAC-guarded) in the Catalog.

Tags can come from Git-backed YAML, Catalog Ingestion API, or UI (RBAC-guarded).

Configurable precedence (default: Git > API > UI).

View tags: all catalog viewers.

Edit via UI/API: restricted to an IDP Tag Editor role or above.

Protected Keys (e.g., tier, domain) editable only by admins/automation.

Catalog Entities API supports tag CRUD and search: tags.key=value, tags.key:*.

Webhook/event on tag changes for downstream automation (optional).

Dashboards in IDP

All IDP dashboards (Catalog/Scorecards/Workflows/TechDocs) support Filter by Tag and Group by Tag.
