Zusammenfassung
At least two types of ageing processes affect digital records: media ageing and semantic ageing. We argue that the main challenges for digital preservation arise from semantic ageing, that is, the evolution of data formats. The article analyzes a type of document that is particularly vulnerable to semantic ageing: the digital maps produced by researchers on built heritage which combine spatial and thematic data. We describe a solution for format migration based on the ontological modeling of the thematic data.
