Hi Pat -    (01)

The space itself and "optimal space" is a question which may not be
solved for many years.    (02)

What I'm really getting to duplicating the process from: a need, to a
design,  to the equivelant of construction documents and quality
control, resulting in organized built spaces. As the process is
perfected in physical space using CAD, BIM, GIS efficient processes
and ontologies made for physical applications may prove useful to
design and build the kinds of structures  you note below.    (03)

Especially projects where the same participants are involved -
government organization, architect (classic or new), contractors,
business services, general public. Some of the participants needs,
skills, oversight and....use or appreciation of a well designed
space...are the same. The problem today, which many excellent people
are working on, is that basically anyone can create and introduce
their own versions of any type of "data building". Nearly all are
accessible to the general public with little to no oversight and
master planning about how all the buildings are working together, they
are just evolving and accumulating.    (04)

The point is useful cross-overs need to be made. Without reinventing
the wheel as much as possible.    (05)
