[x3d-public] key-value database in VRML

Had an idea some time ago to store protos as objects in a objectdb where metadata are converted into categories for the Odb search function. Conversion would preferable been done through a add-in fetching meta data and suggest categories for different classes of proto.

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? John Sent from Mail for Windows 10 From: vmarchetti at kshell.com

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?  Vince Marchetti
