Kind of an abstract stack for a computer, yes?
But look at turtle5 (or 4 for C turtles): English.
Often that is exactly the semantic language of
choices. Vladimir points out RDF, etc., and
fine, but it is more common to find English.
For example, from a recent draft spec [1]:
"<Vehicle> A motor-driven conveyance designed to carry or transport
something (Operator, passengers, cargo)
Example: (See Resource Category Examples Tables)
Source: IEEE 1512, GJXDM, VEDS, FEMA Resource Typing (FRT), ROSS
NOTE 1: GJXDM uses the term "Property" for Aircraft, Boats, Commercial
Vehicles etc.
It excludes trailers and boats from "vehicle"
NOTE 2: GJXDM also has "Property Physical Details" (physical desc)"
NOTE from Len: the source names records of authority where authorities
expressed a choice. One
hopes these aren't in conflict. Substitutions are dangerous so limiting the
choosers of choices
to only a few turtles can be advantageous. This is the component
specification problem of
political inclusion by reference (consensus on steroids).
So given this and a wrapper that points to whatever points to
the choosing turtles, the turtles dance together pretty well.
RDF may be too expensive for the job. English may work well
enough. RDDL anyone?
Types may be ambiguous. That is fine. A system without superpositions
is a) inflexible b) non-organic. It is a question of the a) resources
consumed making a choice including time b) the consequence(s) of a wrong
choice c) the payoff.
What is the impact of using substitution groups on the turtle stack?

OK, learning from Vladimir's example how about this stack?
1. People
2. private ideas
3. private tools
4. shared ideas
5. shared vocabulary/language
6. shared tools
7. shared processes
8. people
examples of each layer
1. me
2. hungry
3. stick I use to pick my teeth
4. "non-zero sum game"
5. English
6. XML (or the hammer/nail/lumber combination for construction)
7. network computer application (or an assembly line factory)(or a
freeway)
8. mouse wigglers (or widget buyers)
