Custom metadata is metadata that you define for a source system for which Metadata Command Center does not provide connectors by default. Custom metadata integration is ingesting custom metadata from any source system into the catalog. Such source systems are called custom source systems.
You can configure a custom catalog source to load metadata into the catalog using the following sources:
•Metadata definition files
•Cloud Data Integration
•Java SDK
Preview Notice: Effective in the July 2023 release, loading metadata into the catalog from Cloud Data Integration and Java SDK are 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.
To ingest custom metadata from a source system, perform the following high-level tasks:
Create a custom model or reuse a system model
A model defines the structure of metadata stored in the catalog. It contains classes, associations, and attributes of the metadata. By default, Metadata Command Center provides models for multiple source systems from which you can extract metadata. These models are called system models. However, to ingest metadata from source systems for which Metadata Command Center doesn't provide a system model, you need to first define a custom model.
Use a custom model to load metadata from any source system into the catalog to meet your business requirements. For example, you are a data analyst in your organization and you need to prepare a report on the annual sales on your e-commerce website. The data that is required to prepare the report is stored in Microsoft Access Database and you are expected to ingest the data from Microsoft Access Database into Data Governance and Catalog. Since Metadata Command Center does not provide a model for Microsoft Access Database, you can create a custom model to ingest metadata from this specific source system into the catalog.
Create a custom catalog source type
A custom catalog source type represents the type of custom source system from which you want to ingest the metadata. After you define the custom model or reuse a system model, create a custom catalog source type.
Create a custom catalog source
Based on the custom catalog source type, create a custom catalog source. When you create the custom catalog source, provide the details of the metadata that you want to ingest from the source system into the catalog.
