Docs For Class FileDataPart

Description

Each Asset has one of the AssetType supported by the Repository. There are

also zero or more RecordStructures required by the Repository for each AssetType. RecordStructures provide structural information. The values for a given Asset's RecordStructure are stored in a Record. RecordStructures can contain sub-elements which are referred to as PartStructures. The structure defined in the RecordStructure and its PartStructures is used in for any Records for the Asset. Records have Parts which parallel PartStructures.
