The paper "Specification of Graph Translators with Triple Graph Grammars" by Andy Schürr discusses the importance of data integration in software tools and the limitations of existing integration tools. It introduces triple graph grammars as a solution to specify interdependencies between graph-like data structures at a high level. The author highlights that while graph rewriting systems are useful for in-place modifications, they are not suitable for integration or traceability tasks that require translating or checking consistency between complex data structures. The paper provides examples of related graph-like data structures, such as syntax trees and control flow diagrams, and outlines the characteristics of fine-grained $m$-to-$n$ inter-graph relationships. It also emphasizes the need for annotations and dependencies between inter-graph relationships, which are crucial for incremental data integration tools. The paper proposes modeling these relationships as separate correspondence graphs and specifying data integrators using productions that rewrite three graphs in parallel.The paper "Specification of Graph Translators with Triple Graph Grammars" by Andy Schürr discusses the importance of data integration in software tools and the limitations of existing integration tools.
