The fundamental layer needed for a successful
institutional repository is the Network Infrastruc-

that correspond to the five DRSC components.
The CDOI (Chinese Data Object Identifier
System) implements the ID service component
by providing the basic Add, Delete, Update and
Search functions and further functions such as
Registration, Locating, Value-added and Agency
Management services. The Metadata service com-
ponent is running in WMMS (WeST Matadata
Management System) that stores the metadata in
XML database. The content of a digital resource
is managed by WFMS (Web File Management
System) and the Annotations and Logs are sepa-
rately maintained by TAGSYS (TAG SYStem) and
