Correct. I was not faulting the authors. I only intended to point out that
the community needs to work with them to flesh out the model.
I hate to throw in jargon and buzzwords into a discussion, but we will need to
either build or adopt an ontology (if one exists, please point me to it) for
the various Lego(tm) bricks and parts that have been modeled if we want to
extend and adopt (or adopt and extend) this work. What we are talking about
creating are object models of bricks and parts with properties (shape,
dimensions, surface markings, connection points, behaviors -- slide, rotation,
etc., ....) This leads me to the conclusion that we need an ontology.
