Digital Preservation is the process of preserving digital assets used in Virtual Museum domain for the longer period possible. In a wider sense, it is a “set of activities required to make sure digital objects can be located, rendered, used and understood in the future. This can include managing the object names and locations, updating the storage media, documenting the content and tracking hardware and software changes, to make sure objects can still be opened and understood” (source: http://www.digitalpreservationeurope.eu/what-is-digital-preservation/).
"Digital preservation combines policies, strategies and actions to ensure access to reformatted and born digital content regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time."(ALA 2007:2)
It includes “the act of maintaining information, in a correct and Independently Understandable form, over the Long Term" (CCSDS 2002: 1-11), and "all activities concerning the maintenance and care for/curation of digital or electronic objects, in relation to both storage and access." (Research Councils UK 2008: 6)
