A Domain represents a top-level business area — Finance, Sales, Customer, Human Resources, Supply Chain. Domains set the accountability boundary: they determine who owns data quality SLAs, who stewards assets, and how quality scores are grouped across the platform.
Sub-domains refine ownership within a domain. Finance might contain sub-domains for Accounts Receivable, Accounts Payable, and FP&A — each with its own steward and quality targets.
Cardinality rules
A single table can have a different domain than some of its attributes. For example, customer_orders lives in the Sales domain, but its customer_id attribute belongs to the Customer domain, and payment_status belongs to Finance — because stewardship of each field’s meaning comes from a different team.
How to create a Domain
Navigate to Semantics → Domain
Click Semantics in the top navigation bar, then select Domain.
Add a Domain or Sub-domain
Click + Add Domain to create a top-level domain, or select an existing domain and click + Add Sub-domain to nest one underneath it. Save
Click Save. The domain appears in the list and is immediately available as a facet in the Asset catalog.
Domain list
The Domain page shows all domains and sub-domains with:
Assigning a domain to an asset
Open any asset’s detail page → right-side panel → Domain field → search and select. A domain can also be assigned in bulk from the Asset catalog using the multi-select action menu.
Use cases
Quality accountability by business area — view average quality scores grouped by domain on the Quality Score page. Identify which business area has the most degraded data and assign the right steward.
Scoped access control — grant a team access to all assets in the Finance domain without listing every table individually. Domain membership drives RBAC resource scoping.
Impact analysis — when a pipeline fails, filter Issues by domain to see which business area is affected and notify the right owner.
Sub-domain granularity — large domains like Finance often need distinct ownership per function. Sub-domains (Accounts Receivable, FP&A) let each sub-team own their slice while rolling up scores to the parent domain.
Use the Asset catalog’s Domain filter to audit which assets have no domain assigned — these are the most likely to be unowned and under-monitored.
