I’ve returned to this task, and I have two questions: First, DatasetGraphFactory.GraphMaker builds a graph, but inference is configured at the model level. Can I use a DatasetGraphFactory.GraphMaker to create an inference-enabled graph?
Second, assuming I have a DatasetGraphFactory.GraphMaker working, what do I do with it? I don’t see any methods on Dataset, DatasetGraph, DataService, FusekiService, or any of the associated builders or factories that allows me to register a GraphMaker for use by the system.

GraphMaker a try. Assuming that works (I’m sure it will), having a configuration option becomes lower priority for me, but for ease of use it would be good to raise an issue.

There is also a code-way to customize the creation of graph in a datasets (DatasetGraphFactory. GraphMaker) but there isn't a way to configure that from a Fuseki configuration Hi Ian, Interesting usage and I think I've heard about a similar one before. There is also a code-way to customize the creation of graph in a datasets (DatasetGraphFactory.GraphMaker) but there isn't a way to configure that from a Fuseki configuration file unfortunately. Sorry about that - do you want to raise an issue?
