Class XmlPropertiesFileMetadataLoader

java.lang.Object

org.alfresco.repo.bulkimport.metadataloaders.XmlPropertiesFileMetadataLoader

All Implemented Interfaces:

MetadataLoader

public final class XmlPropertiesFileMetadataLoader
extends Object

MetadataLoader that loads metadata from an (optional) "shadow" properties file in XML format. This shadow properties file must have exactly the same name and extension as the file for whom it is storing metadata, but with the suffix ".metadata.properties.xml". So for example, if there is a file called "IMG_1967.jpg", the "shadow" metadata file for it would be called "IMG_1967.jpg.metadata.properties.xml". The metadata file itself follows the usual rules for Java properties XML files, with a property with the key "type" containing the qualified name of the content type to use for the file, a property with the key "aspects" containing a comma-delimited list of qualified names of the aspects to attach to the file, and then one Java property per metadata property, with the key being the Alfresco property QName and the value being the value of that property. For example (note escaping rules for namespace separator!): Metadata for IMG_1967.jpg cm:content cm:versionable, custom:myAspect This is the value of the cm:title field. This is the value of the cm:description field. workspace://SpacesStore/3da6c395-3a4b-4a57-836d-8e5 This is the value of the custom:myProperty field. 2001-01-01T12:00:00.000+01:00 Notes:

• Java XML properties files fully support Unicode characters (unlike the original properties file format), so use of this class is strongly recommended over and PropertiesFileMetadataLoader.
• the metadata must conform to the type and aspect definitions configured in Alfresco (including mandatory fields, constraints and data types). Any violations will terminate the bulk import process.
• associations are not yet supported
• dates, times and date times must be stored in ISO8601 format (although note that Alfresco ignores timezone modifiers)

Description copied from interface: MetadataLoader

Method that populates the type, aspects and properties to attach to a given file or space.

Specified by:
