The Standard

Shared definitions

Reusable types referenced by every entity. They keep identifiers, dates, money and addresses consistent across the whole standard.

Machine-readable source: common.schema.json. See also data model conventions.

Identifier

string

An opaque, stable identifier assigned by the system that holds the record. Identifiers are unique within a data set and carry no meaning of their own.

pattern: ^[A-Za-z0-9._:-]+$ · min length 1 · max length 128

Date

string

A calendar date in ISO 8601 extended format (YYYY-MM-DD).

format: date

DateTime

string

A date and time in RFC 3339 format, including a UTC offset (for example 2026-03-14T19:00:00-07:00).

format: date-time

pattern: ^[0-9]{3}-[0-9]{3}-[0-9]{3}$

Extensions

object

Implementation-specific data that is not part of the standard. Keys must be reverse-domain namespaces owned by the implementer (for example "ca.example.app"), so extensions from different vendors never collide.
