I have an OpenURL implementation with a relatively intuitive API (viz. OpenURL itself). Here is the JavaDoc for it: http://pubserv.oclc.org/oom-j/jars/docs/docs/api/index.html . You should recognize most of the classnames from the standard itself. A brief description can be found here: http://q6.oclc.org/2006/08/openurl_object.html . I haven’t publicized this implementation much because we’re so busy using it internally. If you’re interested, though, let me know and I can help you get started.
