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, Swagger API is a source system from which you can extract metadata through a Swagger API catalog source. 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 relationships, and creating links between those assets and their business context.
You can only extract metadata using this catalog source.
Preview Notice: Effective in the November 2025 release, the Swagger API catalog source is available for preview. Preview functionality is supported for evaluation purposes but is unwarranted and is not supported in production environments or any environment that you plan to push to production. Informatica intends to include the preview functionality in an upcoming release for production use, but might choose not to in accordance with changing market or technical circumstances. For more information, contact Informatica Global Customer Support.
Extraction and view process
To extract metadata from a source system, configure the catalog source and run the 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:
After you verify prerequisites, perform the following tasks to extract metadata from Swagger API:
1Register a catalog source. Create a catalog source object, select Swagger API, and specify values for connection properties.
2Configure the catalog source. Specify the runtime environment, configure the metadata extraction capability, and add filters for metadata extraction.
3Optionally, associate stakeholders. Associate users with technical assets, giving the users permission to perform actions determined by their roles.
4Run or schedule the catalog source job.
After you run the catalog source job, you view the results in Data Governance and Catalog.
About the Swagger API catalog source
You can use the Swagger API catalog source to extract metadata from the Swagger API source system.
