Task criteria¶

Purpose: Reference document specifying how the 103-task HED catalog was scoped, how tasks were selected, and the rules for classifying variations vs. aliases vs. non-variations.

Companion to the process criteria.

Sections are numbered so that they can be cited; a citation such as “task criteria 2.1” means subsection 1 of section 2 of this document.

  1. Task selection criteria

  2. Task naming rules

  3. The task inclusion test

  4. Variation criteria

  5. Borderline case policy
