  "description": "A jurisdiction-neutral duty concept that Obligations are classified under, and that interpretive records may reference when they concern the concept rather than any single statutory duty. Categories are the commensurability layer: two Obligations in different jurisdictions are comparable because they carry the same category, not because they share text. An Obligation joins its categories via skos:exactMatch; a Determination that concerns a category generally references it via of:anchors. A Category is NOT itself a duty: it is created by no Term, binds no duty holder, and carries no jurisdiction. Anything that is actually owed by someone under some instrument is an Obligation, not a Category.",
