[x3d-public] key-value database in VRML

I am actually thinking of the keys (names) as Shapes as well, like a key that unlocks a door.  Any key-value database that has keys as objects and values as objects should do (Thinking of Java public interface RenderableCollection extends Map<RenderableObject,RenderableObject>, RenderableObject {} or some such).  Perhaps an example would help?  But yeah, a switch in a proto might work.

Has anyone done it?    What value might this lend to a web authoring environment?  How many web-based X3D authoring environments are there?

The Metadata nodes could form the basis of a key-value database attached to X3D scene elements. It might be interesting to think about new nodes, implementable as Prototypes, that are motivated by treating each visual element's Metadata as a key-value set and performing search and comparison operations. -- for example, could you write a Prototype that was visually rendered as a Shape identified by some condition on the Shape's Metadata?

Has anyone built a key-value database in VRML (not stored VRML in a key-value database)?
