Digital Preservation:
- Series of managed activities necessary to ensure continued access to digital materials for as long as necessary. (Digital Preservation Coalition. 2008)
- Planning, resource allocation, and application of preservation methods and technologies to ensure that digital information of continuing value remains accessible and usable.
- Regardless of the challenges of media failure and technological change.
- Accurate rendering of authenticated content over time. (Evans, Mark; Carter, Laura. 2008)
- Long-term preservation
Continued access to digital materials, or at least to the information contained in them, indefinitely.
- Medium-term preservation
Continued access to digital materials beyond changes in technology for a defined period of time but not indefinitely.
- Short-term preservation
Access to digital materials either for a defined period of time while use is predicted but which does not extend beyond the foreseeable future and until it becomes inaccessible because of changes in technology.
