This is one of InLOC's direct properties.

The InLOC abbr is intended to be a string related to a human-readable language, recognisable by a user of that language and not e.g. a URI. It is a little like "label", but labels are human-readable alternatives to identifiers, while abbreviations are shorter alternatives for titles that are already human-readable.

As applied to a LOCstructure, if there is a commonly used abbreviation or acronym for the structure or framework, it should be put here. E.g., "EQF".

Occasionally different languages use different abbreviations for titles. See Multilinguality for an explanation of the InLOC treatment of this, which is very similar to other specifications.

Several other specifications use "abbr" for something similar. See e.g.:
