Preservation becomes an important infrastructural service for information systems. Many research works have done in past decades. The most popular preservation approach is migration, which transfers and/or transforms digital objects between two computers or two generations of computer technology. However, it is difficult for custodians to decide which migration solution should be chosen. This is because the migration selection depends on the old situation (e.g., digital objects, technical infrastructure and restriction rules) and the current situation (e.g., system requirements and organization requirements). Therefore, in order to obtain the old situation of an information system, the authors in this paper design a new solution to retrieve information about the old situation from stored metadata.
