The Rationale Behind "Internationalized" Resource Identifiers

The "names" of graph nodes in RDF utilize IRIs or "Internationalized" Resource Identifiers.  They are "internationalized" in the sense that the allowable character set consists of the full range of Unicode characters which means Chinese characters, Hindi script and other languages can be utilized as names. This differs from URIs or Uniform Resource Identifiers (IRIs are a superset of URIs and URLs).
