Yes, and possibly the client library contains the functions for the network 
access system.

With this multi-tiered abstraction model, I am just trying to think on a 
long-term and large scale in terms of adoption and true universality.

There is no shortage of geometric data formats.  I think the way to really 
universalize is to create a data system (network of libraries and programs.)

For large complex programs, the more abstraction the better.

I think it is great to start simple, but we should also try to envision the 
future uses and requirements, which will allow the design to evolve without 
huge setbacks.

One of the issues that comes up immediately is how to expand this 
format/system to parametric data.

Maybe a more important question, which would likely provide the answers to a 
lot of these details, is what would be the central defining metaphor for the 
format?  (example:  with Unix, "everything is a file" has been central to the 
design of all things Unix)

Maybe we should come up with a label other than "format"?   

Database Specification?
