I thought I need SHACL, SWRL, ShEx, SPIN, R2RML and more to handle a Semantic RDF Graph — I was proved wrong. Knowledge graphs have become more and more popular due to their unprecedented efficiency in (1) integrating data from many sources with different data schemas,
(2) handling dynamic, redundant, incomplete or inconsistent information,
(3) their ability to reason, validate and deduce new knowledge from existing facts.
