"categorical graphs" papers???

[Galchin Vasili]

Hello,

   Below was a message posted a couple of days ago. I 
have couple questions:

1) The content ....  is it by Youlian or someone else
      this person is quoting?

2) Is "categorical graph" (sounds very intersting) a
     concept that appears widely in the literature?
   If so, what are some paper  references, i.e. papers
    I can download?

Thank you and regards,

Vasili N. Galchin

Abstract
In practise of information systems many new paradigms
have emerged in 
the 
last decade. Of these paradigms the 'objects oriented'
and 'object 
based' 
are the most prominent. Many of the new languages and
tools in practice 
involve new and informal notions that often are based
on graphical 
represen- 
tations. In this presentation I will present a
mathematical structure 
called 
"categorial graph", with wich one can formally
describe a number of 
notions 
that became important with the comming of these
paradigms. Among 
others, 
these notions are "(complex) objects", "graphically
defined types" and 
"objectivication". The categorial graphs serve as a
language in which 
one 
can reason with the new notions. We give a semantics
for the categorial 
graphs by translation them into a logic which is
tailored for the 
categorial 
graphs. This means that the core of the categorial
graphs is an 
intrinsic 
part of the logical language. The logic has a strong
connection with 
arrow 
logic.
