This principle enables libraries, archives, and museums to apply one conceptual data model to physical objects and digital objects.

Representation information includes, for example, technical information about the file formats that are used to bundle data (i.e., bitstreams) into digital objects that can be accessed and stored.

In most cases, a digital data object is a File (digital object).
