The package you want to look at is:
org.alfresco.repo.content.metadata
Found in the Repository project, this contains the various meta-data extractor class implementations and the MetadataExtractorRegistry.

The configuration for the meta-data extractors (you can add your own) is found in config/alfresco/content-services-context.xml in this section:


   <!– Content Metadata Extracters –>
   <bean class="org.alfresco.repo.content.metadata.PdfBoxMetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.OfficeMetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.MailMetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.HtmlMetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.MP3MetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.OpenDocumentMetadataExtracter" parent="baseMetadataExtracter" />
   <bean class="org.alfresco.repo.content.metadata.OpenOfficeMetadataExtracter" parent="baseMetadataExtracter" init-method="init" >
      <property name="connection">
         <ref bean="openOfficeConnection" />
      </property>
   </bean>

Maybe a stupid question but I have tried to find the directory but I couldn't find it. Is this because I use the installer from the enterprise edition? Anyway, do you know where I could find the package org.alfresco.repo.content.metadata? Is it in a JAR file or something?

You need to download the SDK to access the source - the package structure mentioned will be in the 'repository' project source/java dir.

Thanks,
