```jena-sparql-api-jgrapht``` Module #41

Closed MohamedRagabAnas closed 3 years ago

MohamedRagabAnas commented 3 years ago

Hello, On the home page of this project, you kindly have mentioned that you maintain the jena-sparql-api-jgrapht for converting RDF and SPARQL queries into graphs to apply the subgraph isomorphism, but I can't find this module inside the project modules.

Can you please direct me to the implementation of this module.

Thanks in advance for your reply.

Hi,

The jgrapht graph wrapper which provides a directed pseudo-graph graph view over an RDF graph together with the index structures are part of this project: (It seemed useful to factor the jgrapht-jena binding out as a separate module) https://github.com/SmartDataAnalytics/SubgraphIsomorphismIndex

The application of this system in the context of query containment is here: https://github.com/SmartDataAnalytics/jena-sparql-api/tree/master/jena-sparql-api-query-containment

There are also test cases for the system but unfortunately I still did not get around to fix some of the issues there were reported with further queries.
