6.1.11 Digital Repository Software, Data Management and Preservation Systems Digital repository software is generally that software which supports storage and access to the digital content. It should incorporate indexing and metadata systems that manage information about the content, and a variety of tools to find and report on the content. Data management is the management of the byte stream, or data, that the system is responsible for. This may include back up procedures, multiple copies and changes. Preservation processes are those that ensure the content remain accessible in the long term, that the content is still meaningful and that the data management system’s tasks are documented and maintained. All three of these steps are necessary to achieve long term preservation to content.
