## Lineage

- **OpenPermit (2014-2016)**, the OpenPermit Foundation's permitting API specification
  (github.com/openpermit/openpermit.github.io; specification released under Creative Commons
  Attribution 3.0, CC BY 3.0) and its reference implementations (OpenPermit.NET and siblings, MIT License,
  copyright 2015 The OpenPermit Foundation Inc.). ORI credits it as lineage. ORI copies no text or
  code from it and claims no endorsement.
- **SheetPros/OpenPermit** (2025), the root of the GitHub fork network this repository belongs to.
  It carries no licence file. ORI credits it and copies none of its content.
- **corelotorg/OpenPermit** (Corelot, 2025-2026), the canonical repository, where ORI's public drafts are published
  under Apache-2.0 (code) and a CC0 notice (specifications).
- **jeremiahhorstick/OpenPermit** (Jeremiah Horstick, 2025-), a historical fork and the target named in the October 3 candidate packet. This release continues in corelotorg/OpenPermit.

As Jeremiah Horstick states it, the chain runs Sheet Pros, then Corelot, then his fork. GitHub's
fork graph lists both the Corelot and the Jeremiah Horstick repositories as direct forks of
SheetPros/OpenPermit. Details: [`CREDITS.md`](CREDITS.md#lineage-and-provenance).
