The role of metadata in digital preservation

The problem of preserving digital information has now taken on great importance. As the amount of digital information continues to grow, the concern about maintaining access to this information accessible will increase. As elements for describing digital documents or DLO (Document Like Object), metadata play an important role in providing information about the logical aspects of the DLO they refer to, and consequently, in all the tasks related to preservation. At the same time, metadata are digital information, so their preservation must be borne in mind. In this respect, several projects and work groups have been devoted to studying the use of metadata for digital preservation and the preservation of metadata themselves.
