The library provides a simple API for wrapping your data access in few lines of code.
An instance of ApplicationManager represents an entire set of application resources that fuel the system. The list is compiled
in an XML document as a setup configuration.
ApplicationManager manager = new ApplicationFactory()
Once all the resources are loaded properly, you can open an instance of QueryEngine to create a query application to serve
SPARQL query execution. The app manager also provides MaterializationEngine to enable your application doing data export
from database tuples to RDF triples.
