Re: 2 Questions on Syntax

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.
