Data Catalog

A Fabric-wide catalog of Power BI reports, semantic models, and their KPIs (measures / columns), with reverse lookup (which KPI is used in which report), lineage, a topic (workspace + folder) tree, global search — and an access-request front door.

Full design & phases: PLAN.md.

What it does

• Every workspace and item in your tenant, scanned on a schedule into a Lakehouse
• Lineage and ownership per item
• Search across the whole tenant
• Runs entirely inside your own tenant

Architecture (two-tier)

Scanner notebook (sempy + semantic-link-labs, scheduled)
        → Catalog Lakehouse  data_catalog_lh  (Delta cat_* tables)
        → Direct Lake semantic model  "Data Catalog Model"
        → this Rayfin app (reads via fabric_proxy executeQueries UDF)

• scanner/ — the Fabric notebook that crawls every accessible workspace and writes the cat_* Delta tables. See scanner/README.md.
• src/ — the React 19 + Vite 7 + Fluent UI v9 SPA (Fabric brokered auth).
• rayfin/ — Rayfin service config (rayfin.yml) + the AccessRequest data entity.

Develop

npm install
npm run build:fabric   # tsc -b && vite build — must be green
npm run dev            # local dev against the mock backend

Deploy

Target: Rayfin Apps workspace ${FABRIC_WORKSPACE_ID}, tenant fc3a8969-… (MCAPS), capacity prdsweden (resume before deploy).

npx rayfin up --workspace-id ${FABRIC_WORKSPACE_ID} --tenant ${FABRIC_TENANT_ID} -y

Status

Phases 0–8 built & deployed: scanner + catalog lakehouse + Direct Lake model, the five views (report list · KPI→reports reverse index · lineage · topic tree · global search), nightly refresh, and the access-request + approval workflow. Live at the hosting URL from rayfin up.

Credits & Acknowledgements

The access-request/approval workflow and parts of the Fabric plumbing are adopted from the open-source work of Andreas J. Rederer (@DaSenf1860) — notably fabricplatformgovernance and ms-fabric-sdk-core. See CREDITS.md for the full list of adopted elements and attribution.

Getting started

npm install
npm run dev
npx rayfin up --workspace-id <your-workspace-guid> --tenant <your-tenant-guid>

Any workspace or item id this app needs is read from the environment, with no default.
