Graph and Model Transformation: General Framework and by Hartmut Ehrig, Claudia Ermel, Ulrike Golas, Frank Hermann

By Hartmut Ehrig, Claudia Ermel, Ulrike Golas, Frank Hermann

This publication is a complete rationalization of graph and version transformation. It incorporates a special advent, together with simple effects and purposes of the algebraic thought of graph variations, and references to the ancient context. Then primarily half the e-book comprises special chapters on M-adhesive different types, M-adhesive transformation platforms, and multi-amalgamated differences, and version transformation in accordance with triple graph grammars. within the ultimate a part of the publication the authors learn software of the ideas in a variety of domain names, together with chapters on case reviews and gear help.


The ebook may be of curiosity to researchers and practitioners within the components of theoretical computing device technology, software program engineering, concurrent and disbursed platforms, and visible modelling.

4. The graph H1 is obtained from G by removing m1 (L1 − K1 ) and adding R1 − K1 . Note that we could easily have a rule setFlag without any application condition. In particular it is enough to include in the left-hand side of the rule the turn variable pointing to R. In contrast to that, the application condition ∀ (b6 , ∃ c6 ) of the rule enableR cannot be removed, although it is also a positive application condition. In particular, this condition is nested twice, which is needed to specify that every other enabled resource has two waiting processes.

Part III presents the formal techniques for model transformations based on triple graph grammars (TGGs), which provide validated and verified capabilities for a wide range of the challenges listed above. , closer to the implementation. 1 Mapping meta modelling notions to graph terminology Meta modelling notion Graph terminology Model Type graph TG Inheritance Node type inheritance in TG Class Node in type graph TG Association Edge in type graph TG Multiplicities Node and edge type multiplicities in TG Class attributes Attribute types belonging to node types Model instance TG-typed, attributed graph G with typing morphism G → TG Object Node in TG-typed graph G Reference Edge in TG-typed graph G that must not violate certain multiplicity constraints.
