Bruce, I wrote something about using TopBraid Composer to create a specialized version of a standard vocabulary at http://topquadrantblog.blogspot.com/2011/03/how-to-extend-ontology.html , if that helps with the mechanics of creating your ontology.
Google does no RDF-based reasoning or inferencing. They took part in the schema.org design to give people a way to embed semantics in web pages to help the SEO of those pages. When schema.org was first announced, their position on RDFa's potential role was a bit vague, but since then people have figured out how to use RDFa to take advantage of schema.org--for example, see TopQuadrant alum Gavin Carother's blog entry at http://gavin.carothers.name/2011/06/04/schema-org-as-rdfa/ . schema.org does offer a way to define custom subproperties of its schema's properties (see example at http://www.w3.org/wiki/HTML_Data_Vocabularies#Extending_microdata_vocabularies), but it is a syntax they made up themselves. At least it uses URIs, so adding the appropriate RDFS properties (e.g. using { < http://schema.org/Person/MP> rdfs:subPropertyOf <http://schema.org/Person> } with the w3.org example) would define the same semantics in your own ontology so that semantic web standards compliant software like TopBraid would understand the relationship between these properties.
