Then the point made that RDF is a machine friendly but somewhat unnatural way to represent knowledge has some merit. It sounds as if when we stripe the RDF namespace into the XML, we get partial benefits. Better than nothing but not the best in strict terms of what an RDF system can deliver. Also, one may want to know the document type to determine if a set of rules can be created to cover issues such as the meaningfulness of the containment relationships. It seems that less and less can be done without a priori knowledge of the document type. Hmmm... perhaps some other forms of KR should be investigated as well. len From: Thomas B. Passin [mailto:tpassin@c...] The problem, if it is a problem, is that the relationship in XML between an element and its children is no more or less than "containment" or "childhood" or some such notion. Any other relationship or meaning that you want to assign cannot come from the markup structure itself. It is like having a labeled graph where some of the arcs are missing labels. You can still construct the graph, but you have to guess at or infer the labels. With good practices, good naming conventions, etc., you could have a processor infer those things reasonably well, thus extracting metadata as you say. But it is not totally cut and dried.
