Metadata Manager uses Metadata Exchanges to load metadata from different metadata sources into the Metadata Manager warehouse. To run a Metadata Exchange, you create a resource in Metadata Manager that represents the metadata source. When you load the resource, Metadata Manager uses the Metadata Exchange for the resource to extract and load the metadata.
The Metadata Exchanges use the Metadata Manager Agent to extract the source metadata and reformat it into a usable format, the IME interface format. The Metadata Exchanges then use the PowerCenter workflows, consisting of worklets, sessions, and mappings, to extract, transform, and load metadata from the IME-formatted files to the Metadata Manager warehouse.
This entire process is known as the
metadata integration process
. The PowerCenter repository contains the workflows that extract and load the source repository metadata.
