Working with the basic RDF model I get the feeling that the RDF data model is too flat. One of the aspects that has a contradiction with the world around us is that in RDF there is (speaking in terms of frame based theory) only one type of slot: Property. In real world we see objects or things (RDF: Resources) with attributes and relations between objects. Attributes are dependent on their objects in which they are contained, in a (binary) relation two objects are independent in existence but connected. For example the weight, color of the eyes and day of birth are typically attributes of a Person instance; the father, mother, spouse, car and bank account are independent objects related to a certain Person. I would make a plea for a second type of slot in the RDF model: Relation or BinaryRelation. I think that my suggestion is close to the CKML fundamentals, maybe the CKML model would be the outcome when we think things all over.Received on Thursday, 9 March 2000 05:23:11 UTC
