Concepts and Terminology

All language-specific OpenTracing APIs share core concepts and terminology. These concepts are so central and important to the project that they have their own repository ( and semver scheme.

This specification repository houses two important files:

  1. is a versioned description of the current pan-language OpenTracing standard
  2. describes conventional Span tags and log keys for common semantic scenarios

Both are versioned and the github repository is tagged according to the rules described by the versioning policy.
