Manage domains in Semarchy xDG

Domains in Semarchy xDG are organizational categories where you can group related assets. You can manage Domains centrally or let Domain owners handle them. Each asset belongs to only one Domain at a time.

Overview

In a Semarchy xDG, a "domain" typically refers to a logical or thematic grouping or classification of assets based on their subject matter, purpose, or usage. Domains help organize and categorize assets, making it easier for users to discover, understand, and work with data effectively.

For example, in a data catalog for a retail company, domains could include "Sales," "Inventory," "Customer Data," and "Financials." Each of these domains would contain relevant assets related to that specific aspect of the business. Domains provide a high-level structure to the catalog, helping users navigate and locate the data they need within a larger dataset.

Browse domains

To browse domains:

  1. Select Domains & Initiatives in the navigation drawer.
    Each domain appears with its description, count of assets, and owners.

  3. Click a domain to open it.
