Description Garming Sam 2019-02-19 21:55:49 UTC
Every time you add a new subclassOf relationship in the schema, the time to add the piece of schema increases dramatically. After 20 or 30 pieces of chained schema, the time it takes is tens of minutes or more.

There are no massive chain in the standard schema, but it should be possible to make them without a massive time complexity blow-out. The code needs to be changed to avoid duplication of work.
