DEPENDENCE RESCISSION AND SEMANTIC INTERPRETATION: KEY STRATEGIES TO LONG-TERM PRESERVATION OF DIGITAL ARCHIVES
There are three states of archival objects and their corresponding management measures. Clarifying the continuity or discreteness of signals and semantics of three states is very important in preservation. For objects at digital state, low-order logic dependencies with software and hardware dependencies as the core need to be removed. And for objects at data state, high-order logic dependencies with semantic associations as the core need to be removed.
