CSA Loom — the Microsoft Fabric experience for Azure tenants where Fabric isn't yet available: lakehouses, warehouses, notebooks, semantic models, Activator rules, Data Agents, across Commercial, GCC, GCC-High, and DoD IL5

Tutorial 07 — Publish & discover data products

Share data across the platform using the three shipped surfaces: the API marketplace, the Unified catalog, and data product templates. 20 minutes.

Prerequisites

  • Workspace with noaa_silver_daily table from Tutorial 02
  • Workspace Admin (or a steward role) to publish

There is no marketplace CLI and no YAML data-product manifest. The flows below are the real, shipped UI surfaces.

Surface A — Publish a table as an API

Expose a lakehouse/warehouse table as a managed API via APIM.

1. Open the source item

Left nav → Workspaces → open your workspace → open the lakehouse or warehouse holding noaa_silver_daily.

2. Publish as an API

In the item's Weave menu → Publish as an API (POST /api/thread/publish-as-api). Loom creates an APIM API product from a Synapse Serverless view (or Databricks SQL endpoint) over the table.

3. Subscribe and try it

Left nav → API marketplace (/api-marketplace). The published APIM products and APIs are listed. From a product you can Try it in-browser, copy the subscription key, or Use as source to wire the API into a Data Agent or a mini-app.

Surface B — Discover & request data assets

4. Browse the Unified catalog

Left nav → Unified catalog (/catalog). It indexes data assets across Purview (Gov) or Unity Catalog (Commercial). Filter to find your table (e.g. by domain: weather if you tagged it in Tutorial 02 §11).

5. Request access

Click Request access on an asset. This triggers the underlying access-policy request — a Purview data-access policy request (Gov) or a UC entitlement request (Commercial). The approval workflow lives in those governance systems, not in the Loom Console.

Surface C — Spawn a data product from a template

6. Create a Data product template item

Open your workspace → New item → category Data Engineering → Data product template. The Data Product Template editor opens and loads the curated template grid (GET /api/items/data-product-template).

7. Pick a template

Select a template to see its components, description, and estimated monthly cost.

8. Spawn into a workspace

Choose a target workspace and a display name, then click Spawn into workspace (POSTs { workspaceId, displayName } to POST /api/items/data-product-template/<slug>/instantiate). On success you land on the new Data Product Instance editor, which lists the spawned component items and their status/health.

What's next

Cleanup

  • API: delete the published API product from the source item's Weave menu (or the API marketplace) if your deployment supports it
  • Template instance: delete the Data Product Instance item from the workspace tree (right-click → Delete)

Troubleshooting

  • "Publish as an API" gated: provision/grant the APIM service the action reports
  • Asset not in the catalog: confirm Purview/UC scanning has indexed the source, then refresh
