A content enricher, shown in Figure A.2, “Content Enricher Pattern”, is a pattern for augmenting a message with missing information. The ServiceMix EIP content enricher is roughly equivalent to a pipeline that adds missing data as the message passes through an enricher target. Consequently, when migrating to Apache Camel, you can re-implement the ServiceMix content enricher as a Apache Camel pipeline.

Example A.4, “ServiceMix EIP Content Enricher” shows how to define a content enricher using the ServiceMix EIP component. Incoming messages pass through the enricher target,
test:additionalInformationExtracter, which adds missing data to the message. The message is then sent on to its ultimate destination, test:myTarget.
