Rationale Size is useful for ensuring the correct number of bytes from storage have been retrieved and that an application has enough room to move or process files. It might also be used when billing for storage. Data constraint Integer Object category Representation File Bitstream Applicability Not applicable Applicable Applicable Examples 2038927 Repeatability Not repeatable Not repeatable Obligation Optional Optional Creation/ Maintenance notes Automatically obtained by the repository. Usage notes Defining this semantic unit as size in bytes makes it unnecessary to record a unit of measurement. However, for the purpose of data exchange the unit of measurement should be stated or understood by both partners. 27 May 201527
