Open Data Standard for Amateur Ice Hockey
Version 1.0 · Released 2026-09-23 · ionformat.org
ION Format is an open, human-readable data standard for amateur ice hockey.
Any app, any platform, any device — if it speaks ION, the data moves freely.
Inspired by the belief that hockey data belongs to the players, not the platforms.
Today, every hockey app stores data in its own private format.
Switch apps → lose your records. No portability. No interoperability.
ION Format fixes this:
| Type | Description | App |
|---|---|---|
INX |
Game record (goals, shots, penalties) | IonNow |
ACE |
Lineup & roster | IonAce |
GYM |
Training session | IonGym |
KIT |
Equipment inventory | IonKit |
ICE |
Team & player data | IonIce |
Every ION record starts with a common header:
ION|1.0

SRC|IonNow|1.1

ION Format follows semantic versioning:
MAJOR.MINOR.PATCH
1 . 0 . 0
Rule: A parser for 1.x must be able to read any 1.y file where y <= x.
Unknown tags are silently ignored.
ION records are designed to fit within a single QR code (Version 40, ECC M):
ION-PART|1/3|{data}
ION-PART|2/3|{data}
ION-PART|3/3|{data}
Anyone can implement ION Format. No license required.
To add ION support to your app:
ION Format is community-driven.
