Questions:
1. What is the functions related to SPARQL query processing? I am looking
at SPARQL_Query.java, ActionSPARQL.java, etc., but this kinda
reverse-engineering does not work well until now. I will look into the
JavaDoc more, but I would appreciate if I can get an enlightment here.
There is another way to hook in that may be useful.
Instead of the HTTP request lifecycle, hook into the transaction
lifecycle on the dataset.
A DatasetGraph wrapper means you can add the functionality to any
existing dataset.
This is in jena-arq.
All Fuseki requests on the data are performed inside a transaction so if
you catch a write transaction, and when it commits, trigger SPIN processing.
Fuseki uses Jena's assembler mechanism to describe datasets so they can
be setup and configured with needing application Java code
