 == Loading and Saving Aspect Models

 Either the model is loaded as an RDF model where the abstraction level directly corresponds to the RDF/Turtle
 serialization, or the RDF is parsed into a native Java Aspect model representation where the abstraction level
 corresponds to the SAMM concepts. Both approaches have different use cases and advantages and both are supported by the
