-This is a discussion of how a user (developer or end user) would use an ebRIM catalog for a simple use case and will hopefully assist the reader in evaluating the usefulness of the ebRIM metadata catalog.  It is intentionally going to focus on the use case, rather than the technology involved.  The only mention of technology buzzwords will be now in mentioning that the ebXML documents can be generated using a XSL stylesheet from OGC W*S services, and Omar can be interfaced using SOAP, JAXR, or a RESTful KVPs.  In addition Omar can classify objects using all the standard OGC/ISO taxonomies. Technical comments will be in italics.
