ABSTRACT
With the boom of digital resources, there are urgent requirements to set up and manage Institutional
Repositories (IRs) for companies and/or organizations. Cloud computing opens a new paradigm to
build IRs by providing diverse services. We apply cloud services in the building of IRs and present a
new model, which is based on digital object model and service component architecture, and consists of
five service components, namely ID, metadata, content, log, and annotation service component. The five
components are implemented by five corresponding clouds. These clouds provide two kinds of services:
Web service and mashup service. We develop a framework and a code generation tool to generate an
IR that can be used to manage the digital resources by invoking the five cloud services. Our approach
is applied to the digital library on the history of water conservancy in China of Tsinghua University
Library to demonstrate its feasibility.
