Reworking OHP: the Road to OHP-Nav

The original OHP specification was intended to define a simple but comprehensive ASCII protocol to deal with hypertext objects. However, this was too broad an issue to be addressed by a single protocol. Therefore, we have focused on navigational hypertext and produced a specification that is more powerful within this more specific domain. This paper describes the design of OHP-Nav, defined both in IDL as an interface and in XML as a tagged ASCII protocol. We believe that this reworked definition can form a basis for focusing on the real issues of interoperability in open hypermedia systems. Introduction The Open Hypermedia Systems Working Group (OHSWG) has promoted research towards interoperability amongst hypermedia systems and integration with the World-Wide Web. A number of sub groups have been established to address the various issues. In this paper we describe the development and current status of OHP-Nav, a standardized set of services for retrieving and navigating hypermedia o...
