I assume you mean "without using SPARQL"?

Any complex constraint expressed using SPARQL can be turned into a 
(SPIN/LDOM) template. This means that some experts can prepare 
high-level lego bricks for people who don't know SPARQL. The items 
mentioned under "Property declarations" are basically the most common 
patterns, and those should of course be built-in. We may identify other 
recurring patterns that should also be covered by built-ins (such as 
templates).
