org.apache.chemistry.opencmis.client.parser.MetadataParser
This interface is used to extract metadata from content. An instance is responsible to parse the content and extract the metadata. The metadata must be stored in a CMIS property bag. Implementations of this class are created by the Configurator depending on the Content-Type to parse and the corresponding parser configuration @author Jens
