The Pid webservice is a driver for Handle System's resolver technology. It eases the creation of persistent identifiers and their bindings to attributes such as web locations with the use of a Soap protocol. This means it is system agnostic: an external application offering web methods that can be integrated into your catalog and archival system solutions. All with the purpose to offer a consistent delivery via pids of your web resources to yourself, your users and external discovery services alike.
