Реификация
Реальное упоминание термина "реификация"
в конференции -
==================
This is actually consistent with how
we are modeling it. Start with point
to point:
(bs1) -> (bs2)
where bs1, bs2 are business systems
containing software components (A
system owns software components).
The arrow in the middle gets REIFIED,
because it is also a system
containing the integration
componentry:
(bs1) ->(is1) -> (bs2)
which turns the arrows into simple
links with no associated software
components.
Publish subscribe semantics are
modeled thus:
...........................................->(is2)
-> (bs2)
(bs1) ->(is1) -> (ts1)-->>
...........................................->(is3)
-> (bs3)
(здесь идет распараллеливание
процесса 1 на строчку выше и ниже -
на процессы 2 и 3, что трудно
передать доступными на этом сайте
средствами)
"ts1" stands for "topic system"
which is a virtual system as you
suggest. Since it's REIFIED as a
system, it can now hook up to
interface systems that in turn feed
business systems, and publisher and
subscriber are decoupled in the
graph.
The data structures being moved by
the infrastructure are represented
as CWM Record (for flat files) or
XML objects, which are tied to a
concept of "port" which at a micro
level is where the association is
attached to the system.

Определение
==================
We used used to throw "reification"
around a lot in psychology
department bull-sessions, a few
decades ago, so it is not new. How
about this discussion, from
Wikipedia:
"REIFICATION
From Wikipedia, the free
encyclopedia.
Find out how you can help support
Wikipedia's phenomenal growth.
Reification, also called
hypostatization, is the logical
fallacy of regarding an abstract
concept, such as "society" or "technology"
as if it were a concrete thing.
This fallacy is committed when
manipulations that are only possible
on concrete things are said to be
done on an abstract concept. The
fallacy is also committed when an
abstract concept is referred to as
if it bore no relation to the
concrete things that it is an
abstraction of.
Note that this fallacy assumes the
world-view of epistemological
realism. Reification is not regarded
as a fallacy by those who take up
the viewpoint of epistemological
idealism.
In knowledge representation,
reification is sometimes used to
represent facts that must then be
manipulated in some way, for example
to compare logical assertions from
different witnesses to determine
their credibility. The message "John
is six feet tall" is an assertion of
truth that commits the sender to the
fact, whereas the reified statement,
"Mary reports that John is six feet
tall" defers this commitment to
Mary. In this way, the statements
can be incompatible without creating
contradictions in reasoning."
