01
Getting Started
OpenPlay is a structured JSON language for describing educational football plays independent of rendering or simulation.
Explore OpenPlay
A structured language for describing football players, assignments, timing, and decisions. Demo Schema v0.1 is experimental.
02
Document Structure
Every document uses a common envelope plus offense-specific or defense-specific sections.
03
Coordinates
Field-relative coordinates keep records independent from screen size. X is 0–53.3 yards. Y is 0–100 yards from the offense's end zone.
04
Players and Alignments
Player records provide stable identities, positions, labels, initial coordinates, and team side.
05
Assignments
Discriminated records connect one player to a route, block, rush, coverage, handoff, or supporting job.
06
Routes
Route assignments are ordered semantic path segments, not renderer-specific drawing commands.
07
Blocking
Blocking assignments encode pass protection and run responsibilities without tying them to a diagram library.
08
Defensive Coverages
Defensive documents combine player-level jobs with a whole-call description of front, coverage, pressure, and disguise.
09
Timeline
Timeline events provide ordered semantic moments for animation without embedding animation-library code.
10
Decision Points
An offensive decision point pauses a concept at a meaningful read and presents bounded football choices.
11
Narratives
Narrative fields make each record useful even when no diagram is running.
12
Examples
The canonical offensive and defensive playbooks in this repository are the executable examples for version 0.1.
13
Future Vision
The long-term commitment is to publish the schema, documentation, and a reference renderer under stated open licenses.
