Structural metadata can be defined as metadata required to describe the internal structure and the component relationships of a digital object.
Structural metadata contains information on how the digital object has been created, e.g. metadata collected when digitizing a book. The organisation should document relevant information about the ‘containers’ of the files in the structural metadata and decide what information is to be preserved and if a formal standard is to be used in preserving this type of metadata, for example: use of the METS standard.
Structural metadata is important to be able to render the digital object authentically in the future.
Correctly rendering of the digital object may be lost if structural metadata is missing.
