In the media-external item type, the data
property is a user-defined property computed by the atg.repository.FilePropertyDescriptor
class. If the url
property is a relative URL, then data
is a java.io.File
object, which references the file.
As part of defining a ContentRepositoryItem
, the item definition must supply a length and a last modified value. In a media-external item, these values are automatically extracted from the File
object returned from data
.
