Initial version of Predicate Mapping Algorithm.
This is just a rapid prototype, still needs lots of work.
As for the data, I've skipped the files in the dbpedia and linkedmdb folders because git was having troubles. I've left one file from each in there for reference, but the rest you'll need to retrieve from google drive.
