Navigating Spaces: The Semantics of Cross Domain Interoperability
The Open Hypermedia Protocol (OHP) developed by the Open Hypermedia Systems Working Group (OHSWG) allows components of a system to discuss Navigational Hypermedia, but it does not yet address the needs of other hypertext domains. The focus of Structural Computing has been to recognise the need for structure at all levels of computing, if OHP could express the structure of multiple domains then it could be used to facilitate this goal. The Fundamental Open Hypermedia Model (FOHM) has been developed to incorporate other domains into the OHP data model, forming a semantic language that can potentially be used to discuss any structure. In this paper we look at the ‘cross-domain fertilization’ that takes place when several domains are brought together in this way and describe what it means to encounter structures from one domain in another.
