Purpose and description
Enable an agent to recognise, track and reason about an extra period provisionally understood as an additional phase of a sporting contest beyond its scheduled regulation play.
In sport, an extra period is an additional interval of play beyond regulation time, used under the competition's rules to help determine a winner when the score is tied.
It can be Determine whether the recorded contest state satisfies the sourced condition for an extra period.; Identify the next extra period and the state that must carry into it.; Track official progression while distinguishing playing time from interruptions.; Check whether proposed participation or restart actions comply with the applicable extra-period rules.; Evaluate whether the period has ended and identify the authorised next contest phase.; Flag unresolved rule interpretations or conflicting official records before treating an outcome as settled..
Distinguishing features
It is identified as a distinct additional phase by the applicable contest rules, rather than inferred solely because play runs beyond an expected finishing time.
Its activation follows a specified condition in the parent contest; a tied score alone does not establish that an extra period is required.
Its boundary is distinguishable from time added to compensate for interruptions within a regulation period.
Its duration and ending condition must be recorded separately: elapsed time alone may not determine completion.
It is distinguishable from a separate tie-breaking procedure even when both occur after regulation.
Scope
+ The extra period's relationship to regulation play and the parent contest
+ The rule-dependent condition that authorises an extra period
+ Period sequence, timing, clock behaviour and termination
+ Participant eligibility and state carried forward from preceding play
+ Scoring, completion and the decision to end or continue the contest
- The full lifecycle and organisation of the parent contest
- Regulation periods and routine intervals between them
- Compensation for time lost during a regulation period
- Standalone shootouts or other separate tie-breaking procedures
- Employment overtime and extensions to administrative deadlines
Characteristics
- Parent contest
- Reference to the contest containing this extra period An extra period inherits its competitive purpose and relevant preceding state from a specific contest.
- Applicable rule context
- Sport, competition, stage and effective rules edition The same period label can imply different activation, timing and termination rules.
- Activation condition
- Source-defined condition; unresolved if not established Determines whether entering the extra period is authorised.
- Period ordinal
- Positive integer within the extra-period sequence Distinguishes repeated extra periods and identifies sequence-dependent rules.
- Lifecycle state
- Conditional, authorised, underway, suspended, completed, abandoned Separates a possible extra period from one that has actually begun or finished.
- Timing specification
- Source-defined timed or untimed structure, clock basis and stopping rules Prevents wall-clock duration from being confused with official playing time.
- Official playing time
- Elapsed or remaining seconds or minutes, with clock direction and applicability recorded Supports progression tracking without assuming that every extra period uses a countdown clock.
- Termination condition
- Source-defined time, scoring, completion or combined condition Determines when play must stop and whether further contest procedures are required.
- Carried contest state
- Referenced score, eligibility, sanctions, possession and resource state at entry, as applicable Establishes what persists or resets when the additional phase begins.

Extra-period identity Establishes what counts as an extra period and which contest and rule context give it that identity.
The label alone cannot distinguish a separate additional phase from added time or another tie-breaking mechanism.
Phase boundary
Separates the extra period from adjacent phases and similarly named extensions.
Distinct additional phase
Record the authority for treating this segment as a distinct extra period; this is a research requirement, not an established registry definition.
- What does the relevant authority call an extra period, and how does it distinguish that phase from regulation? definition
- Does the recorded segment represent a separate period, compensation for lost time, or a different tie-breaking procedure? boundary
Contest rule context
Locates the period within the contest and the rules applicable to that contest.
Governing rule selection
Identify the competition, stage and effective rules edition that determine how this extra period operates.
- Which parent contest and competition stage contain this extra period? boundary
- Which rule edition or authorised competition variation governs its use? provenance
Activation and entry Captures why an extra period becomes necessary and the state from which it starts.
An agent must establish permission to proceed and cannot assume that every unresolved regulation result triggers extra play.
Activation decision
Evaluates the contest condition and authority needed to initiate extra play.
Extra-play trigger
Record the sourced activation predicate, its observed inputs and any required official decision.
- What result or contest condition requires or permits this extra period? definition
- Who confirms that the trigger is satisfied, and what record supports that confirmation? provenance
- May the contest enter this period now, or is a prerequisite still outstanding? action
Entry state
Determines what persists, resets or is selected before the period begins.
Carryover and restart
Represent the transition from preceding play without assuming universal rules for scores, sanctions, possession or playing direction.
- Which scores, sanctions, participant restrictions and unused resources carry into this period? boundary
- What interval, selection procedure or restart action must occur before play begins? action
Extra-period play Represents the temporal and participation conditions under which the additional phase proceeds.
Extra play may change timing or participation conditions, so regulation settings cannot be copied without verification.
Timing and interruptions
Tracks the period's official temporal extent and handling of interrupted play.
Official progress
Separate official playing progress from wall-clock timestamps and record the applicable interruption rules.
- Is this period timed, and if so what duration, clock direction and clock-stopping rules apply? measurement
- How are suspension, resumption and any extension within this extra period handled? action
Participation conditions
Records eligible participants and changes specific to extra play.
Extra-period eligibility
Establish the participant configuration and permitted changes for this phase under its governing rules.
- Which participants are eligible at entry, and which preceding exclusions remain effective? boundary
- Do participant numbers, substitutions or timeout allowances change for this extra period? action
Termination and disposition Determines when the extra period ends and what its completion means for the parent contest.
Ending an extra period and deciding the contest are separate determinations that require explicit rules and evidence.
Period ending
Evaluates the condition that closes this particular extra period.
Ending-condition evaluation
Record the applicable ending rule and the evidence that it has or has not been satisfied.
- Does this period end on time expiry, a qualifying score, completion of a play sequence, or a combination of conditions? definition
- Can a pending play, sanction or review delay confirmation that the period has ended? boundary
Contest continuation
Connects the extra-period result to the next authorised contest state.
Result and next phase
Distinguish the period's recorded result from the decision to declare a winner, play another period or invoke another procedure.
- How does this period's score or result contribute to the official contest outcome? measurement
- If the contest remains unresolved, is another extra period, a separate tie-breaker or another disposition authorised? action
- Which official record establishes the final result and resolves any conflicting accounts? provenance
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.

Recalled without web access and unsourced; every item is a lead to verify.
- Regulation period - A regulation period belongs to the scheduled ordinary playing time; an extra period follows it conditionally.
- Stoppage time - Stoppage time compensates for time lost within a football period; extra time adds separate periods to help resolve a tie.
- Penalty shoot-out - A penalty shoot-out uses a sequence of designated attempts rather than an additional interval of ordinary match play.
- Extra time - Extra time can denote the complete extension of a match, while an extra period is one constituent interval.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of extra period this model covers, and on what evidence? provenance
What the second pass must settle
- Does vr.tr.extra-period specifically denote a sporting extra period, or does the source registry intend another kind of additional activity interval?
- Does the registry concept cover one additional period, the entire extra-play phase, or both usages?
- Which sports and rule systems fall within the intended concept, particularly those using untimed additional play?
- Which existing Vercy world model, if any, already owns this concept and should serve as its single source of truth?
- Which authoritative sources establish the intended boundaries between extra period, overtime, extra time, added time and separate tie-breaking procedures?
