Subject: [xtm-wg] [xtm-cms] Re: XML Conceptual Model Report
Great job on the model report. I think we are doing great progress. I have a few comments: Class Hierarchy: To me a link have a linkend instead of a role. The role is more a property like type and scope. Also, I see TopicAssociation being another derivation of Link like all others TopicOccur, TopicName, Scope, etc... TopicAssoc is a specialized type of Link with multiple Topics. TopicOccur is a specialized type of Link with a Topic and a Resource. If TopicOccur has different constraints and nothing in common with TopicAssoc, why should TopicOccur be a specialization of TopicAssoc? Identity: Identity looks to me like a type of Occurrence. Occurrence: I think TopicOccurence is missing the other end containing the Topic. On the diagram, it only contains OccurrenceRole. I am thinking that some of the derivation of Link can be self anchors since a Link is a Topic. More below about self anchors. Also, a ResourcedTopic should reference a ResourceObject with the Locator just being the method to resolve to the object. That way the model shows the relationship between Topics and the "real world". By topicmaps knowing explicitly about the "real" resource objects, it is possible to find out about the topicmap from resources themselves. The BOS would be the list of ResourceObjects. Self Anchors: I think that Occurrence, Scope, Type, and Name links can be self anchors because Links are Topics. When creating an Occurrence, a Topic is linked to a Resource. So, you have a the Topic role "associated" to a Resource, and the TopicOccurence it self as a Topic "associated" to the Resource. There are two Topic existing in the same structure that could be the same thing.
