All it really does is transform bits of information from the HttpServletRequest into an OpenURL 1.0 Context''''''Object and pass it along to the OpenURL 1.0 resolver. On the back end, the WikiD servlet merely relays the OpenURL response to the client unmolested. The Context''''''Object is built from these Entities: * Referent - an Identifier taken from the pathInfo of the request ** If the pathInfo is a URI, it is used directly ** If the pathInfo is a WikiName, it is transformed into an item-level URI by prefixing it with the URI assigned to CollectionWikiPages (viz. info:sid/localhost:CollectionWikiPages''''''.) Allowing this prefix to be implied for WikiName''''''s preserves the wiki aesthetic. * Referring''''''Entity - The Referer (sic) URL from the HTTP header (i.e. the page that contained the hotlink that was clicked) * Requester - a Descriptor for a user (if authenticated) * Service''''''Type - Private''''''Data containing the arguments to be applied to the Referent (e.g. action=edit) * Referrer - The serverPath/context of the request (as a clue to the OpenURL resolver for how to interpret the Private''''''Data Service''''''Type) The OpenURL 1.0 protocol is highly abstract. These abstractions are instantiated via Properties files when the WikiD servlet gets initialized. These instantiations are geared towards recognizing the special needs of the WikiD Referrer Entity and producing a response appropriate for that context.
