kandi X-RAY | ReGraph Summary

ReGraph is a Python library typically used in User Interface applications. ReGraph has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. However ReGraph has 9 bugs. You can download it from GitHub.

The ReGraph Python library is a generic framework for modelling graph-based systems. In this context models are viewed as graphs and graph transformations --- as a tool to describe both the system evolution and the model evolution read more about the approach. ReGraph provides various utilities for graph rewriting which can be used for modelling the evolution of a system represented by a graph subject to rewriting. The rewriting functionality is based on the sesqui-pushout rewriting procedure [7]. In addition, the library enables a user to define a typing for models (graphs) that gives specifications for the structure of the models. This later functionality allows both to preserve the specified structure during rewriting and to propagate the changes to the specifications up to the models. ReGraph contains a collection of utilities for rewriting graphs and hierarchies of graphs. It supports two backends: NetworkX graph objects and on Neo4j property graphs stored in a graph database.

Is there a way to have edge attributes as placeholders in a regraph hierarchy?

QUESTION

Is there a way to have edge attributes as placeholders in a regraph hierarchy?

Asked 2019-Jan-15 at 14:45

I am working on a python script that is using the regraph library based on networkx. I created a hierarchy that contains different graphs that are typed to eachother. In one of the graphs, I want edges to have attributes, for example a name. When I do this, I get a message saying that the homomorphism is broken, because the graph it is typed to does not have the exact same edge attributes.

I know this might not be what regraph is designed for, but is there a way to specify an edge attribute in a graph in the hierarchy OR a rule that does not only take patterns but also node names into account?

I have already tried adding empty attributes to the other graphs in the hierarchy, this does not work.

Install ReGraph

In order to install the ReGraph library you can either use the latest version in PyPI:. or install from the source by cloning the repository using SSH.
If you want to use the Neo4j-based backend of ReGraph, you need to install the Neo4j database (see installation instructions). Moreover, ReGraph uses the APOC Neo4j plugin, currently not included in the community edition. To install the plugin see the instructions. ReGraph uses Neo4j Bolt Driver for Python, therefore, having set up your database, you need to provide to ReGraph's API the address of the bolt server (for example, bolt://127.0.0.1:7687) and your credentials for connecting the database (i.e. user and password).
