Long term preservation of RD

Digital preservation refers to the reliable preservation of digital information for several decades or even centuries. Hardware, software, and file formats will become outdated, while the information must be preserved. Reliable digital preservation requires active monitoring of information integrity and anticipation of various risks. Metadata, which describes for example the information content, provenance information, and how the content can be used, has a key role in this.
