Act ID format reference

ACT-ID v0.3 defines nine canonical entity types. ACT-U is the atomic, bindable unit — everything a bond framework references. The other prefixes are supporting structure (classification, variants, hierarchy, criteria, thresholds, objectives, mappings, institutions). See the methodology for the full model.

ACT-U-XXXXXX
Use-of-proceeds atomic / bindable

The specific, financeable thing a bond's capital pays for. What frameworks bind to.

ACT-A-XXXXXX
Economic activity

ISIC/NACE-aligned producer-side classification. One activity, many use-of-proceeds.

ACT-V-XXXXXX
Variant

Attribute-qualified execution variant of a use-of-proceeds (e.g. drought-tolerant vs heat-tolerant).

ACT-H-XXXXXX
Hierarchy node

A taxonomy-specific category that organises use-of-proceeds. Not bindable itself.

ACT-C-XXXXXX
Criterion

A measurable eligibility requirement (paired with a threshold).

ACT-TH-XXXXXX
Threshold

A specific value or range applied against a criterion.

ACT-O-XXXXXX
Objective

Environmental, social, or governance goal (carries structural properties).

ACT-M-XXXXXX
Mapping

An asserted relationship between canonical records — scoped and typed.

ACT-I-XXXXXX
Institution

A body that publishes, develops, or administers a taxonomy.

ACT-T-XXXXXX
Taxonomy framework

A classification framework — carries versions, lifecycle state, and purpose.
