I haven't heard of anyone doing this with RDF generally, but there are wuite a few people doing this with DAML, which is quite similar. The DAML folks use ordered facts instead of using named slots for each component (despite my repeated warnings that their approach is very inefficient compared to using named slots!) So I'm both familiar with, and approve of, your approach.
Have a look at examples/zebra.clp, which uses a pre-RDF object-attribute-value triple approach to solving a problem. There's really nothing new under the sun!
