Digital curation refers to the process of managing digital information throughout its lifecycle. It is built upon the notion that the time period that digital information has value to a stakeholder is likely to be greater than the time period that it will be accessible and usable, due to its dependency upon specific technological components. To ensure that information continues to be accessible and usable across changing technological environments, a process of active management is required to ensure that digital information is maintained in a manner that maintains its authenticity and integrity. Digital curation adopts theoretical concepts from a number of subject disciplines, including archival and information science. Key activities in the digital curation process are the need for selection and ongoing appraisal of information, management of digital objects in their original form and preservation action to maintain information access.
