title: Conversion and Emulation-aware Dependency Reasoning for Curation Services
creators: Yannis Tzitzikas Yannis Marketakis Yannis Kargakis
abstract: A quite general view of the digital preservation problem and its associated tasks (e.g. intelligibility and task-performability checking, risk detection, identification of missing resources for performing a task) is to approach it from a dependency management point of view. In this paper we extend past rule-based approaches for dependency management for modeling also converters and emulators and we demonstrate how this modeling allows performing the desired reasoning and thus enables offering more advanced digital preservation services. Specifically these services can greatly reduce the human effort required for periodically checking (monitoring) whether a task on a digital object is performable.
