This site demonstrates the default installation of the open-source OCLC OpenURL 1.0 implementation. Like the OpenURL 1.0 protocol itself, this implementation is highly abstract allowing for an infinite range of entity citation types and resolution outcomes. The default service is an echo of the OpenURL 1.0 request formatted in HTML.
These OpenURL 1.0 request examples were taken from The OpenURL Framework for Context-Sensitive ServicesExample 23: By-Reference OpenURL Transport using HTTP GET
As a novel demonstration of the potential of the OpenURL 1.0 protocol and this implementation, please see the WikiD project.
