Topology-based geometric modeling tackles the issue of representing objects with data structures that encode topological subdivision modeled in vertices, edges, faces, and volumes. Such subdivisions can be represented graphs labeled by dimensions on arcs, while operations used to edit formalized as graph transformations. Among existing models, we consider generalized oriented maps, defined cons...

GTXL (Graph Transformation Exchange Language) is designed to support and stimulate developers to provide their graph transformation-based tools with an exchange functionality regarding the integration with other tools. For this exchange XML was chosen as underlying technology. The exchange of graphs is facilitated by the exchange format GXL which is also XML-based. GTXL uses GXL to describe the...

AGG is a general development environment for algebraic graph transformation systems which follows the interpretative approach. Its special power comes from a very flexible attribution concept. AGG graphs are allowed to be attributed by any kind of Java objects. Graph transformations can be equipped with arbitrary computations on these Java objects described by a Java expression. The AGG environ...

The DRAGOS database eases the development of graphbased applications by providing a uniform graph-oriented data storage facility. In this paper, we extend the existing database by a basic Query and Transformation Mechanism, which facilitates the construction of graph transformation systems. Users can therefore access the database by applying structured rules instead of using atomic operations p...

Knowledge graphs’ reasoning is of great significance for the further development artificial intelligence and information retrieval, especially over temporal knowledge graphs. The rotation-based method has been shown to be effective at modeling entities relations on a graph. However, due lack representation capability, existing approaches can only model partial relational patterns they cannot ha...

Resilience is a concept of rising interest in computer science and software engineering. For systems which correctness w.r.t. safety condition unachievable, fast recovery demanded. We investigate resilience problems graph transformation systems. Our main contribution the decidability two for well-structured (with strong compatibility). prove our results abstract framework transition apply them ...

The framework of graph transformation combines the potentials and advantages of both, graphs and rules, to a single computational paradigm. In this paper we present some recent developments in applying graph transformation as a rule-based framework for the specification and development of systems, languages, and tools. After reviewing the basic features of graph transformation, we discuss a sel...
