The fundamental changes in `jena-arq` are: * The indirection between Update-/Query statements and DatasetGraphs is in `org.apache.jena.sparql.engine.dispatch`. * The execution tracking then comes from `org.apache.jena.sparql.exec.tracker`. It registers a dispatcher that wraps `UpateExec` and `QueryExec` instances with status reporting, such that a listener is notified when query execution starts and terminates. * The class `DatasetGraphOverSparql` is somewhat separate. It is meant as a base class that can be used with the dispatcher system to externalize query execution to e.g. remote endpoints. The changes in `jena-rdfconnection` build upon `DatasetGraphOverSparql` and the dispatcher system. The main change is the introduction of `DatasetGraphOverRDFLink` + corresponding infrastructure. A dispatcher is provided that - for such a dataset graph - delegates each SPARQL statement to a fresh underlying RDF link. This way a remote store can be abstracted as a DatasetGraph for which queries and updates are forwarded to the backend. The purpose is to test/showcase that the dispatcher system can be used to uniformly track remote executions. An assembler is provided to allow configuration of such a dataset such as for use with Fuseki (note that not all configuration options of `RDFLinkHTTPBuilder` are yet wired up). * In Fuseki, a plugin is provided that exposes the tracked executions via a JSON-returning REST method and a corresponding basic HTML view. -- This is an automated message from the Apache Git Service.
