Purpose and description
Enable an agent to recognise a goalkeeper role, assess its holder's readiness and match status, and determine permitted actions under the applicable sport and competition rules.
A goalkeeper is a designated player in a goal-based team sport whose primary responsibility is to prevent opponents from scoring, with permissions, restrictions and equipment requirements defined by that sport's rules.
It can be Identify whether a recorded assignment represents a goalkeeper role in the stated sport.; Resolve who is designated and active as goalkeeper at a specified match time.; Check a proposed goalkeeper action against the applicable rules and current context.; Assess equipment compliance and task readiness before participation.; Compare goalkeeping performance using compatible event definitions and exposure.; Identify the conditions and recording steps required for a goalkeeper replacement or role exchange..
Distinguishing features
The role centres on protecting a team's goal in an identified sport, rather than defending territory or opposing players generally.
Role designation is recorded separately from observed position: standing near the goal does not by itself establish goalkeeper status.
Any special permissions are tied to the applicable rules and circumstances, rather than inferred from the word goalkeeper.
A person may hold the goalkeeper role during one interval and another playing role during another interval.
The model covers amateur and other non-employed role holders as well as professional goalkeepers; employment does not establish the role.
Scope
+ Sport-specific meaning and formal designation of the goalkeeper role
+ Assignment of a player to the role for a team, match or match interval
+ Goal protection, defensive coordination and possession responsibilities
+ Permissions, restrictions and equipment requirements under identified rules
+ Goalkeeper readiness, performance evidence and role transitions
- The player's complete identity, biography and medical record
- Team ownership, governance and general squad administration
- The complete rules and officiating model of a sport
- Employment contracts, remuneration and job advertisements
- Manufacture and maintenance of goalkeeper equipment
- Complete match-event and competition-standing records
Characteristics
- Sport and discipline
- Named sport, discipline and playing format Determines what goalkeeping involves and which neighbouring role concepts apply.
- Governing rules
- Rule authority, edition, competition and local modifications Provides the basis for evaluating permissions, equipment and changes of role.
- Role holder and assignment
- Player, team, match or squad context, effective interval and designation evidence Separates the role from its holder and establishes who occupies it at a given time.
- Participation status
- Context-qualified status such as designated, reserve, active, temporarily absent or replaced Prevents squad membership from being mistaken for current match participation.
- Action permissions
- Permitted, prohibited, conditional or unresolved for a specified action and match context Supports decisions without transferring a goalkeeper privilege between incompatible sports or situations.
- Goalkeeper equipment compliance
- Verified compliant, noncompliant or unverified against identified requirements Helps establish whether the designated holder can participate with the available equipment.
- Task readiness
- Assessed readiness for specified goalkeeping tasks, with assessor, date and limitations Supports selection and training decisions without treating reputation as current capability.
- Goalkeeping performance
- Metric-specific counts, rates or time values with event definitions, observation interval and exposure Makes performance interpretable within the sport and avoids comparisons based on incompatible denominators.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 17 findings · 25 questions.
Goalkeeper identity and designation Establishes which sporting role is meant and who holds it in a specific context.
The name spans sports, while a player's usual position may differ from their current formal assignment.
Sporting sense
Locates the role within a sport, format and governing terminology.
Goalkeeper role boundary
Record the criteria distinguishing a goalkeeper from another defender or a player temporarily covering the goal.
- Which sport and playing format define this goalkeeper role? definition
- What establishes goalkeeper status here beyond a player's location or defensive behaviour? boundary
Holder and tenure
Connects a role holder to a team and an effective assignment interval.
Evidenced goalkeeper assignment
Keep habitual position, squad designation and active match assignment distinguishable.
- Which player holds the role for which team, and during what interval? definition
- Which team sheet, official record or authorised designation supports that assignment? provenance
Goalkeeper permissions and equipment Captures the conditions under which a goalkeeper may act and participate.
Goalkeeper permissions and equipment requirements cannot safely be inferred across sports or rule editions.
Conditional playing permissions
Relates proposed actions to the rules and match circumstances governing them.
Goalkeeper action conditions
Record applicable conditions on handling, possession, movement and interaction with opponents.
- Which rule edition and competition modifications govern the proposed action? provenance
- How do location, possession history and phase of play affect whether this goalkeeper may perform it? action
Participation and equipment
Records goalkeeper-specific participation conditions and their verification.
Goalkeeper participation check
Identify required protective or identifying equipment and any applicable goalkeeper-specific eligibility conditions.
- Which equipment and identifying distinctions are required, optional or prohibited for this goalkeeper? definition
- What evidence establishes that the holder meets the applicable participation requirements? provenance
Goalkeeping tasks and readiness Describes the work expected of the goalkeeper and evidence that the holder can perform it.
Readiness depends on the sport's goalkeeping tasks and the team's tactical expectations, not simply on being listed in the position.
Goal protection
Addresses positioning, threat recognition and responses to scoring attempts.
Goal protection capability
Record the defensive situations the goalkeeper is expected to manage and the evidence supporting readiness.
- Which scoring threats and goal-area situations must this goalkeeper be able to manage? definition
- What recent observations or assessments show readiness for those situations? measurement
Coordination and possession
Addresses the goalkeeper's contribution to defensive organisation and transitions involving possession.
Team-integrated goalkeeping
Specify expected communication, coverage decisions and possession actions where they apply.
- Which defensive coordination and possession responsibilities does the team assign to its goalkeeper? definition
- Under what tactical and rule conditions should the goalkeeper hold position, intervene or initiate a transition? action
Goalkeeper state transitions and evaluation Tracks changes in role occupancy and evaluates performance within the relevant match context.
An agent must distinguish who may act now from who usually plays goalkeeper and must interpret outcomes against the opportunities faced.
Role continuity and replacement
Handles role exchanges, substitutions and periods without an active goalkeeper where applicable.
Goalkeeper transition conditions
Record the trigger, authorisation and effective time of a change in goalkeeper status.
- What conditions and notifications govern replacement, role exchange or temporary absence in this competition? action
- At what recorded event or time does the outgoing assignment end and the incoming assignment begin? boundary
Contextual performance
Connects observed goalkeeping outcomes to their definitions, exposure and limitations.
Interpretable goalkeeping evidence
Keep saves, goals conceded and other selected indicators attached to explicit event definitions and relevant context.
- How are scoring attempts, saves and conceded goals defined and attributed in the selected evidence? measurement
- Which differences in playing time, attempt difficulty and team defence limit comparisons between goalkeepers? boundary
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.
