ice hockey
Enable an AI agent to recognise an ice hockey activity, assess its playing and operational state, and identify actions permitted by its applicable rules and conditions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise an ice hockey activity, assess its playing and operational state, and identify actions permitted by its applicable rules and conditions.
Ice hockey is a team ice-sport in which two sides of skaters, using sticks, try to put a vulcanized-rubber puck into the opponent's goal while skating on a bounded ice sheet, under a codified offside, icing, and body-checking rule set administered internationally by the IIHF.
It can be Classify an observed activity against a declared ice hockey variant and flag missing recognition evidence.; Record puck, player, clock and officiating events to reconstruct the current playing state.; Check a proposed substitution, restart or return from penalty against the applicable rules.; Identify whether a scoring event is confirmed, disputed or awaiting an authorised decision.; Flag rink, equipment or participant conditions that require inspection before play continues.; Explain which observed facts and rule provisions support a proposed next action..
Distinguishing features
Play takes place on ice; a similar activity on a floor or roller surface requires a neighbouring hockey model.
Players contest a puck using hockey sticks; an ice-based stick game organised around a ball, such as bandy, is a neighbouring activity.
Opposing sides seek goals through a shared playing area rather than completing separate skating performances or timed runs.
Recognition requires an ice hockey rule context together with rink and participant evidence; ice, sticks or a puck alone are insufficient.
Participant mobility must be recorded: skate-based and sled-based hockey should not silently inherit identical equipment, movement or eligibility assumptions.
Scope
+ Identification of the ice hockey variant and governing rules
+ Rink boundaries, markings, goals and playing-surface readiness
+ Team deployment, player roles, substitutions and manpower
+ Puck location, possession, scoring and match progression
+ Infractions, penalties, stoppages, restarts and continuation decisions
- Club ownership, finances and organisational governance
- League administration, season scheduling and tournament standings
- Athlete biography, employment and long-term development
- Clinical diagnosis, treatment and rehabilitation
- Arena construction and maintenance beyond their effect on current play
- Equipment manufacture, retail and product certification
Characteristics
- Activity form
- Match, practice, drill, informal play or other declared form Determines whether scoring, clocks, officials and full team deployment are required to judge the activity.
- Applicable rule profile
- Named governing rules, edition and documented local modifications Controls interpretation of contact, rink markings, penalties, restarts and match completion.
- Rink configuration
- Full rink, reduced rink, cross-ice or documented alternative Determines which boundaries, zones and spatial restrictions apply.
- Playing-surface readiness
- Unchecked, ready, restricted or unavailable, with observed reasons Supports a decision to begin, pause, modify or suspend play.
- On-ice deployment
- Count of skaters or sled players and goaltenders for each side Exposes manpower differences, substitutions and possible deployment violations.
- Puck state
- Live, controlled, contested, loose, covered, out of play or unresolved, with location Determines which playing actions and restart decisions are available.
- Match phase and clock
- Declared phase, running or stopped clock, and displayed time in minutes and seconds Distinguishes live play from stoppages and determines whether a phase can end or resume.
- Confirmed score
- Accepted goals per side, with disputed or provisional goals recorded separately Supports assessment of the match state without treating an unresolved scoring event as final.
- Penalty obligations
- Side or participant linked to a ruling, service conditions and remaining duration where applicable Determines participation restrictions and potential changes to manpower.
- Contact permissions
- Rule-specific permissions and restrictions for body contact, checking and protected participants Prevents an agent from assuming that contact accepted in one format is permitted in another.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 11 findings · 21 questions.
Hockey identity and rules Establishes which ice hockey activity is being modelled and which rules govern its interpretation.
The name ice hockey does not by itself settle format, contact permissions or procedural rules.
Activity and variant
Identifies the form of play and the evidence that it belongs to this registry entry.
Recognition and format
Record whether the activity is a match, practice or informal session, its mobility format and the observed basis for classifying it as ice hockey.
- What evidence establishes ice hockey rather than bandy, inline hockey or a skating exercise? definition
- Does this entry include the observed mobility and playing format, or must it link to a neighbouring registered activity? boundary
Governing rule context
Connects the activity to a verifiable rule edition and any authorised adaptations.
Rules and local modifications
Record the governing rule source, edition, competition or session adaptations, and authority for resolving conflicts between them.
- Which rulebook edition and local instructions govern this activity, and where were they obtained? provenance
- Which provisions determine contact permissions, offside, icing and match-ending procedures for this format? boundary
Rink and play readiness Records the ice hockey playing environment and conditions needed to use it.
Puck location and permitted movement depend on rink geometry, while surface and equipment conditions can prevent continuation.
Rink zones and boundaries
Represents the rink features that affect play under the selected format.
Operative rink layout
Record goals, attacking directions, relevant lines, face-off locations, creases, boards and out-of-play boundaries, including absent or modified features.
- Which rink markings and boundaries are operative in this full-rink or adapted format? boundary
- Where are the puck and relevant players relative to the active goals, lines and boundaries? measurement
Surface and equipment readiness
Captures observable conditions that affect whether ice hockey play can safely begin or continue.
Readiness restrictions
Record ice defects, displaced goals, unsecured access points and reported equipment issues together with inspection status and imposed restrictions.
- What observed condition of the ice, goals, boards, gates or participant equipment currently restricts play? measurement
- Who may clear the restriction, and what inspection or corrective action is required before resumption? action
Teams and on-ice deployment Tracks who represents each side, who is participating and how deployment changes.
Ice hockey state depends on on-ice personnel, goaltender presence, substitutions and restrictions on participation.
Roles and eligibility
Identifies participants and the roles they may occupy in the current activity.
Participant role status
Record each participant's side, match identity, permitted role and current availability, including goaltender designation and exclusion decisions.
- Which participants are assigned to each side, and who is designated or currently acting as goaltender? definition
- What roster record or authorised ruling establishes each participant's eligibility or restriction? provenance
Manpower and player changes
Tracks actual deployment separately from the number and type of players permitted.
Deployment and substitution state
Record on-ice counts, goaltender removal or return, changes in progress and the reason actual or permitted manpower differs between sides.
- How many participants of each role are on the ice, and how does that compare with the current permitted deployment? measurement
- May the proposed player change or goaltender replacement occur now, and what conditions must it satisfy? action
Puck play and match progress Records the evolving puck contest, scoring state and timed progression of play.
An agent needs an event-grounded state to distinguish available play from a stoppage, unresolved goal or completed phase.
Puck control and zone state
Relates puck movement and player positions to live-play restrictions.
Puck and zone sequence
Record puck location, relevant touches or control, line crossings and player positions with enough sequence information to evaluate applicable zone rules.
- Where is the puck, is it playable, and which side or participant last touched or controlled it? measurement
- Which observed sequence is needed to determine whether offside, icing or another puck-play restriction applies? boundary
Clock, goals and completion
Tracks elapsed or remaining play and distinguishes provisional events from accepted results.
Scoring and phase status
Record phase, clock state, accepted goals, unresolved scoring events and the rule-dependent conditions for continuation or completion.
- What are the current phase, clock reading and confirmed score, and which scoring events remain unresolved? measurement
- Under the applicable format, should play resume, enter another phase or conclude after the current decision? action
Officiating and resumption Connects observed incidents to authorised rulings, penalty effects and the next permitted restart.
An observed incident, an official decision and its consequences are distinct records with different effects on what may happen next.
Infractions and penalty effects
Captures rulings and their participation, timing and manpower consequences.
Incident, ruling and service
Record the observed incident separately from the ruling, including any delayed decision, assigned penalty, serving participant and conditions for expiry or release.
- What was observed, what ruling was issued, and which official or authorised record establishes that ruling? provenance
- How does the ruling affect manpower, penalty timing and the conditions under which a participant may return? action
Stoppages and restarts
Determines the pending restart and the conditions that must be satisfied before it occurs.
Restart authorisation
Record the reason play stopped, prescribed restart type and location, unresolved reviews or readiness issues, and authority to resume or abandon play.
- What caused the stoppage, and which restart type and location follow from the applicable ruling? definition
- Which decisions, personnel changes or readiness checks remain outstanding before the authorised restart? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence

What the second pass must settle
- Does the registry intend ice hockey to include para ice hockey, informal pond hockey and reduced-rink formats within this entry, or are any already owned by neighbouring models?
- Which governing rule families and editions must the first researched model support, and how should conflicting local adaptations be represented?
- What minimum observation sequence is sufficient to judge offside, icing, puck control and disputed goals without claiming certainty beyond the evidence?
- Which format-specific penalty interactions, clock conventions and match-ending procedures require explicit representation?
- Which authorities and documented criteria govern equipment acceptance, surface readiness and return to play, and where should this activity model defer to facility or clinical models?
