Metadata Extractors

Metadata extractors (Chapter 4) are used to inspect a piece of content when it is uploaded to the repository and extract data. The data is then stored in properties on the content's node.

Metadata extractors are defined in content-services-context.xml. The following table lists the out of the box metadata extractors, and shows what gets extracted and how it is mapped to the node properties:
