It defines which items would be invoked into this evaluator. Items must have the all meta that this evaluator required.

E.g., A (meta: movable, chair), B (meta: movable, table). If the evaluator requires (meta: movable), then A and B will be invoked. If the evaluator requires (meta: movable, car), then, neither A nor B will be invoked.

You can create your Meta definition by using the context menu Create/GVL/MCMC/Meta Definition in the Project Window.

You can have more than one Meta Definition Object in your project. The Smart Suggestion Engine will collect all the meta values and list them in the drop-down list when you are visiting the Meta section.
