The work described a logic-based perspective on information preservation, which would allow a formal definition of the preservation problem as well as a characterization of desirable properties of existing and future preservation methods. To handle both the static and the dynamic aspects of digital preservation, he proposed not the preservation of the digital object itself (e.g. a database) but a set of related properties, such as answers to queries, which could include quality-related information (e.g. provenance) regarding the content of the object itself. Moreover, he argued that data should be separated from the underlying community knowledge, which provides meaning. He finally presented useful connections of information preservation with the related fields of belief change/revision and ontology evolution.

Abstract
The work described a logic-based perspective on information preservation, which would allow a formal definition of the preservation problem as well as a characterization of desirable properties of existing and future preservation methods. To handle both the static and the dynamic aspects of digital preservation, he proposed not the preservation of the digital object itself (e.g. a database) but a set of related properties, such as answers to queries, which could include quality-related information (e.g. provenance) regarding the content of the object itself. Moreover, he argued that data should be separated from the underlying community knowledge, which provides meaning. He finally presented useful connections of information preservation with the related fields of belief change/revision and ontology evolution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
