Labels stored in the repository can be queried directly.

A label is associated with three properties that act as a primary key to identify it:

  • Concept: The name of the report element that this label describes.
  • Label role: This is a URI that specifies what role the label has: standard, terse, verbose, total, negative, etc.
  • Language: This is an IETF language tag that specifies the language in which this label is.

Since labels may be defined and redefined, label objects are further identified with the archive and role of its containing component.
