# STORE-8 — A published contract version is three numbers

*GR-STORE (Part I) · level: extended · profiles: storage-api, editor-client · added in 1.0*

The version is read by consumers that never read the contract itself, a cache validator among them, so it has to be a value that always exists and always compares.

## The rule

> **Normative.** This is the rule.
>
> 1. A workflow's published contract version is three dot-separated non-negative integers.
>
> 2. A workflow whose contract has never been built carries `0.0.0`, the version from which the first build's bump is taken (MAN-18).
>
> 3. The version is never empty and never absent, so a consumer always has a usable value, including one using it as a cache validator (META-6).
