Yuriy:
Alexander Gross has produced "Six Laws of Language..."
See link: http://languag2.home.sprynet.com/f/evishop.htm
FIRST LAW:
"1. All communication takes place in shared contextual space, subject to a more or less complex process of disambiguation, depending on the conditions inherent in the other five Laws. That space can be more or less roughly measured according to a specialized system of cartography."
SECOND LAW:
"2. The Law of Variable Context
If two people share sufficient context, almost any words, including sheer nonsense—or no words at all—will suffice for them to communicate with each other. If two people do not share sufficient context, then not all the words in the world may be enough for them to grasp each other's meaning. Where intermediate degrees of partial, fragmented, or otherwise limited or "noise-distorted" context are shared, communication will be proportionately difficult and/or unsuccessful."
During the discussion on this list, I have developed a context that I associate with your comments. The context of associates terms with variable meaning to a scientific-mathematical context.
Have fun,

"Chicken,
chicken chicken chicken. Chicken?" :))
It
makes sense and even has a value: 1,256,418 - Chickens?
:)
BTW
how many chickens exist (or may exist, or eated, or will be eated, or whatever
regarding the chicks)?

replace the work chicken with system, chickens with systems and you should get

Dear Jack,
Also this reference might help elucidate the notion of patterns in this
context [1], specifically section 4.

Why not start by showing us the

Then was heist 'patterns'?
I definitely do not follow re "heist patterns".
I'm not sure I understand. Are you asking how modeling, analysis,
problems etc. are all similar and/or different? At a high level, one
identifies a problem, analyses it, models it, perhaps codifies said model
in a particular language, and if they need to communicate with others,
then perhaps provide a transformation of said codification to another. Not
necessarily a linear activity, but easy to conceptualize as
such.
Obviously, they are all connected to one another.
My interpretation of these terms is that a problem pattern pertains
to descriptions of commonly occurring issues with regards to various
aspects of systems. I would suggest that the problem themes in Exhibit 3
in [1] could all be candidate problem patterns.
An analysis pattern might then refer to different ways of
characterizing how the problem can be addressed in the systems context. It
would refers to the methodologies, perspectives or other that are useful
in analyzing the domain. Though it need not to, it could take as input
problem patterns and produce analyses of the problems as they apply to
different systems contexts.
A modeling pattern would refer to particular commitments for the
domain description. These patterns might take as input analysis patterns,
and provide as output suggestions / possible ways of modeling the analysis
- whether in natural language, FOL, category theory, but a way of
ontologizing aspects of the analysis. For example, formalizing
/ articulating the notion of "component" as a particular set of axioms
could be a possible modeling pattern.
The distinction between modeling and codification patterns is a bit
less clear to me, though perhaps Giancarlo can clarify his intent with
these terms. Hazarding a guess, I suspect that a codification pattern take
as input a modeling pattern, and produce as output a representation of
said pattern in a specific coding scheme / language. Though I am not happy
with this treatment. But say the modeling pattern suggested that a 3D
design choice was useful for characterizing the notion of role. The
codification pattern would take this 3D design choice and explicate how it
would be represented in say, CommonLogic or OWL...
So let's take the notion of roles. MatthewWest presented a use case
which I believe contained a problem pattern for the role of roles within a
systems appilcation. This spawned a series of discussions regarding how to
treat roles, each perspective contributing an analysis pattern of varying
quality. Some further discussions elaborated on this analysis and went so
far as to tie it to an upper ontology or ways of formally representing
roles in an ontology - these would be modeling patterns. Finally, though
we haven't quite gotten there, perhaps someone would suggest how to
incorporate such a modeling pattern into SysML or formalize it as a set of
Common Logic axioms -- these would be the codification patterns.
Finally, perhaps we want to demonstrate how the notion of Role as
formalized and codified in SysML can be mapped to roles as they are used
in another modeling paradigm. Such an output would be a transformation
pattern.
Is this clear?
Best,
Ali
