Hi,

I took a lot of time, but I finally solved the problem, which was related to the combined use of OPTIONAL with VALUES. It should now work well with the development version of Owlready!

Note that, in your query, you may prefer to use ?name instead of repeating <http://diana/camrest.owl#the%20nirala> in each OPTIONAL clause.
