It does indeed - sorry I should have mentioned that bit. In general we use a pretty basic RDFS structure but the association of types to properties is made with 'schema:domainIncludes' and 'schema:rangeIncludes' properties instead of the more conventional rdfs:domain, rdfs:range. Also we evolve the schema gradually, often adding new type/property associations with each release, so it is best not to build too many assumptions around types being implied by properties. Dan
