I got bitten with this in the RESTful Services pattern.

What does URI stands for?

  • (A) Universal Resource Identifier
  • (B) Uniform Resource Identifier
  • (C) Universal Resource Indicator
  • (D) Uniform Resource Indicator

The most up-to-date answer is actually the second choice above - it’s the title of this RFC. But the RFC explicitly mentions an earlier paper which uses the first choice.

So it seems that “Universal” shifted to “Uniform”, but “Indicator” has always been plain wrong.
