Hi Tony, 1. A container is a value; in your example, you have not specified which property the rdf:Seqs belong to. There's no need to use containers if you just need to assert many properties. You can do compact nesting by using parseType="Resource" 2. I'd love to see a clear statement about this from the real experts. My reading of the spec is that you can either use about="" to refer to the current document, or you can attach a BagID to any Description so that you can make assertions about the Description. I assume you're using this for authority tracking. I haven't used BagID for this because I've not studied how to backtrace the authority for a statement from a triple store produced from BagID. Someone on the list will be able say this is easy or not. Eric At 11:37 AM +0000 3/1/00, tony_hammond@harcourt.com wrote: >Would appreciate any help on these 2 questions: > >1. RDF container syntax.
