Introduction to Microsoft Purview catalog sources

You can use Metadata Command Center to extract metadata from a source system.
A source system is any system that contains data or metadata. For example, Microsoft Purview is a source system from which you can extract metadata through a Microsoft Purview catalog source with Metadata Command Center. A catalog source is an object that represents and contains metadata from the source system.
Before you extract metadata from a source system, you first create and register a catalog source that represents the source system.
When Metadata Command Center extracts metadata, Data Governance and Catalog displays the extracted metadata and its attributes as technical assets. You can then perform tasks such as analyzing the assets, viewing lineage, and creating links between those assets and their business context.
The following table describes the capabilities of the catalog source:

Description
Serverless Runtime Environment
A serverless runtime environment is an advanced serverless deployment solution that doesn't require downloading, installing, configuring, or maintaining a Secure Agent or Secure Agent group. You can use a serverless runtime environment in the same way that you use a Secure Agent when you configure a catalog source.

Extraction and view process

To extract metadata from a source system, configure the catalog source and run the metadata extraction job in Metadata Command Center. Then view the results in Data Governance and Catalog.
The following image shows the process to extract metadata from a source system:
The image shows the process of metadata extraction from a Microsoft Purview source system that begins with prerequisites verification, continues with the creation of the catalog source, and ends with viewing the results and relationships.
After you verify prerequisites, perform the following tasks to extract metadata from Microsoft Purview:
  1. 1Register a catalog source. Create a catalog source object, select the source system, and specify values for connection properties.
  2. 2Configure the catalog source. Specify the runtime environment, optionally configure parameters for the metadata extraction capability, and add filters to include or exclude source system assets from metadata extraction.
  3. 3Associate stakeholders. Optionally, associate users with technical assets, giving the users permission to perform actions determined by their roles.
  4. 4Run or schedule the catalog source job.
  5. 5Optionally, assign a connection to referenced source system assets.
After you run the catalog source job, you can view the results in Data Governance and Catalog.
