# ODCS Implementation Guide
!!! info "Contributor documentation"
These guides are for contributors and maintainers. End users should start with [What is ODCS?](../user/what-is-odcs.md) and [Getting started](../user/getting-started.md).
Guides for building and maintaining the Rust reference implementation of the Open Data Contract Standard (ODCS).
See the canonical documentation index at [Home](../index.md).
**User documentation** (install, CLI, Rust, Python API) lives in [User guides](../user/getting-started.md).
*Last reviewed for release 0.7.0.*
Treat [Upstream sync policy](../upstream-sync-policy.md) as the authoritative upstream policy. The normative ODCS specification lives in the [upstream repository](https://github.com/bitol-io/open-data-contract-standard).
The implementation pipeline:
```text
parse -> Canonical Object Model -> validate -> diagnostics
```
Do not implement execution, pipelines, or transformation semantics without an agreed milestone.
