Subject: [xtm-wg] RE: topicRef to reference assocs as well as topics

Is not <topicRef> resolving to an <association> element bound to provoke syntactic collapsus somewhere? A way I see to resolve it is to attribute to each association, not a name, but a Subject, through <associationSubject>. But since associations are Topics, they do have a Subject, don't they ? And to "associate associations" to make "statements about statements", is there more to do than associate these subjects? e.g. ass # 1 : "Empolis" employs "Graham" : associationSubject # employment ass # 2 : "Graham" has competence in "Topic Maps" : associationSubject # competence ass # 3 : "competence" is a contract term in "employment" : association subject : # contract term The third association is the way I feel "statements about statements". Linking the *particular instances* ass #1 and ass #2 through a *particular association* seems to me an unuseful overload of the Map, since "Empolis employs Graham under contract terms including Graham's competence in Topic Maps" seems quite well described by the three above associations. But maybe you think it does not describe it fully ... Cheers Bernard -------------------------- eGroups Sponsor -------------------------~-~> eLerts It's Easy. It's Fun.
