A Descriptor defines the meaning of an attribute.

It does NOT include private values.

Examples:

• identity.name.given
• identity.birthdate
• address.country
• address.city
• gov.id_number
• health.cert.vaccination.covid19
• finance.tax.residency.country

Descriptors allow:

• apps to request things like “country of residence”
• proof templates to reference attributes structurally
• identities to stay compatible across jurisdictions

Descriptors live in a global registry defined by LIVRE OS.
