The new contribution of the report is to define and analyze the transformation of model fragments in general and the propagtion of graph constraints in particular. With the borrowed context we developed a technique further to the model transformation with triple graph grammars. This allows a transformation of incomplete models which could not be transformed until now. Moreover, we defined under which conditions a graph constraint can be propagated with borrowed context transformations and the model properties are preserved. This is also analyzed in the case study using the modeling framework ABT-Reo.en004 Datenverarbeitung; Informatikmodel transformationtriple graph grammarscompletenessResearch Paper
