The DKPro Core type systems are covered by ASL (although for some reason
there are no ASL headers in the original DKPro Core XML files...). So
in principle there is no problem, and because the original files don't have
ASL headers, they also were not stripped by the aggregation process - again
My understanding is that staying strict to the Apache rules, the contents
of the NOTICE of the DKPro Core artifacts from which the types were
obtained would need to be copied into a NOTICE within the examples
project. If Ruta could obtain the types directly from the Maven artifacts,
the types file and NOTICE inclusion would not be necessary.
