I'm trying to write a (hopefully brief) description of containers for the Primer, and a couple of questions came up. The questions are: 1. can I legally create a container resource (say, a Bag) without using any special syntax, simply by using the ordinary RDF/XML techniques for creating a blank node, and giving it the appropriate properties (including the type property pointing to the pre-defined rdf:Bag resource, and the various li (or explicit _number) properties)? 2. can I also legally create a container resource that has a URI (i.e., that *isn't* a blank node), by using the ordinary RDF/XML techniques for creating a new resource with an ID, and giving it those same appropriate properties (e.g., a type property pointing to one of the pre-defined container type resources)? Note 1: since the above involves essentially the "manual" creation of container resources, if this is legit, ought we to have a constraint that says that the same container can't have multiple rdf:type properties that have inconsistent values (like the same container being both a bag and an alt; on the other hand, how would we enforce it?) Note 2: the syntax or test cases documents may well answer these questions, but I'm neither a RDF/XML nor a N-triples parser (and also, I'm lazy), so please don't refer me to them. Also, please don't refer me to prior RDF Core documented resolutions on containers. I've read them, and can't figure out what they mean (one of the reasons why I'm trying to explain this stuff in the Primer)! Thanks for any light you can shed. --Frank -- Frank Manola The MITRE Corporation 202 Burlington Road, MS A345 Bedford, MA 01730-1420 mailto:fmanola@mitre.org voice: 781-271-8147 FAX: 781-271-875
