Presentations from the Corporation for National Research Initiatives' Handle System Workshop are now available.
Here's a description of he Handle System from its home page:
The Handle System is a general purpose distributed information system that provides efficient, extensible, and secure HDL identifier and resolution services for use on networks such as the Internet. It includes an open set of protocols, a namespace, and a reference implementation of the protocols. The protocols enable a distributed computer system to store identifiers, known as handles, of arbitrary resources and resolve those handles into the information necessary to locate, access, contact, authenticate, or otherwise make use of the resources. This information can be changed as needed to reflect the current state of the identified resource without changing its identifier, thus allowing the name of the item to persist over changes of location and other related state information.
