Metadata extraction automatically extracts metadata information from inbound and/or updated content, and then updates the corresponding node properties with the metadata values.
Metadata extractors provide the mechanism for server-side extraction of values from
added or updated content. Definitions for the default extractors are located in the
<configRoot>/alfresco/content-services-context.xml file.
For more information on the extractors, see the Javadocs for the org.alfresco.repo.content.metadata package.
Also, see the sample configurations in the following files:
- <extension-samples>/alfresco/extension/custom-metadata-extrators-context.xml.sample
- <extension-samples>/alfresco/extension/wcm-xml-metadata-extracter-context.xml.sample.
