7) Summary of the paper's main contribution and rationale for your recommendation. (1-2 paragraphs)
The purpose of a paper is to give an introduction to Graphs transformation and advanced concepts 
for dealing with shortcomings of Graphs Modeling approach. Is same time author state that Graphs provide 
universally adopted data structure and object-oriented compatibilities.

As a drawback of Graphs transformation author mentioned the fact that a node in a graph may, in general, 
have an unknown number of connections. In afterward providing following techniques to mitigate issue:
 - constraints
 - multi-level objects
 - application conditions
 - control conditions

Overall, the article looks as shortened version of "Tutorial Introduction to Graph Transformation" 
from the same author, but rather than generalizing concepts it just a cut content, which makes 
perception and understanding a little bit confusing and hides the general idea of the article.



8) List 1-3 strengths of the paper.  (1-2 sentences each, 
identified as S1, S2, S3.)
 - The structure and arranging the content is sequential and reasonable, 
   but not the content of each section itself



9) List 1-3 weaknesses of the paper (1-2 sentences each,
identified as W1, W2, W3.)
 - The key sentences and concepts are hidden and mixed with a large number of references 
   to examples and could be caught by a person familiar with graphs transformations, 
   which contradict with article purpose of "introduction to graphs". 
   Examples >> Concepts

 - No highlights and conclusions, plain text.

 - Implicit ways of indroducing pros and cons of graphs transformation. 
   As pros dealing with non-linear structures, and cons graph has an unknown number of connections.
