A Metadata Extraction Approach for Selecting Migration Solutions
نویسندگان
چکیده
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, we in this paper design a new solution to retrieve information about the old situation from stored metadata. The viability and efficiency of our approach are evaluated in an experiment, under which there are several sets of image files to be migrated.

Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are...
متن کاملExperimental study on appropriate location of river material mining pits regarding extraction and utilization
River bed sand and gravel are utilized more than mountain materials due to their availability and closeness to the transit roads and sites of usage. Excessive and non-technical extraction of gravel and sand bring a kind of interference in them, leading to many negative consequences. Therefore, presenting solutions to reduce these impacts and infilling mining pits are essential. In this researc...
