Comunica Path to Patterns Optimize Query Operation Actor

An Optimize Query Operation actor that rewrites possible parts of property paths into quad patterns, joins and unions.

Links become quad patterns, inverse paths swap their subject and object, sequences become joins, and alternatives become unions. Arbitrary-length paths, zero-or-one paths and negated paths are not handled.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
