Digital Library Scientist
Our group investigates the policies, organization, and architecture of distributed digital libraries. Our approach is component-based: we view the digital library infrastructure as a toolbox of distributed service components (repository services, index services, etc), which can be combined (or federated) into digital libraries. This component-based
infrastructure is inherently extensible and flexible: components can be evolved independently, new component services can be introduced into the infrastructure, and federations of services can be created and configured according to individual requirements.
Our research program focuses on a number of the key issues that arise within such a distributed digital library infrastructure:
• a digital object architecture
that supports new content types as they evolve.
We work in close collaboration with other researchers in the Cornell, national and international library, computer science, and Internet communities. Our research model is highly applied: building systems and deploying them to collaborators. A prominent example of this model is NCSTRL, the Networked Computer Science Technical Research Library, which is administered by our group. NCSTRL is a distributed digital library of computer science research reports from over 100 institutions worldwide, which uses the Dienst architecture that was invented at Cornell.
