Metadata extraction automatically extracts metadata information from inbound and/or updated content and updates the corresponding nodes properties with the metadata values.
Metadata extractors offer server-side extraction of values from added or updated
content. Definitions of the default set of extractors are in the
<configRoot>/classes/alfresco/content-services-context.xml
file.
Declare a new extractor in
<extension>/custom-repository-context.xml.
The following example shows a new extractor written in class com.company.MyExtracter:
<bean id="com.company.MyExtracter" class="com.company.MyExtracter" parent="baseMetadataExtracter" />
