Metaobject

A metaobject is like a tool that helps other tools do their job. It is like a "helper" tool. Let's pretend you want to build a toy house. You will need a hammer and a saw (the tools) to do the work. The metaobject is like an extra tool that the hammer and the saw depend on - it helps the hammer and saw do their job better. The metaobject is like a special tool that can measure and make sure everything fits together properly and safely.
