Purpose and description
Enable an agent to recognise a ski, record its intended use and physical condition, and determine which fitting, maintenance and use actions require further checks.
A ski is an elongated runner attached to a user's footwear, usually used as one of a pair, that supports sliding travel over snow through its load-bearing surface and permits directional control through its shape, flex and interaction with the snow.
It can be Classify a ski by its declared discipline and observed construction.; Compare geometry and flex evidence with documented user and use requirements.; Check binding mounting compatibility against the ski's documented interface.; Inspect and locate base, edge, body and mounting-area damage.; Select applicable waxing, grip-surface care, edge servicing or repair procedures.; Flag uncertain compatibility, structural damage or pair mismatch for qualified assessment..
Distinguishing features
Provides an elongated running surface intended to slide along its length while supporting a user through a foot attachment.
In the snow-ski sense, is normally controlled separately under one foot; a board carrying both feet requires a boundary check.
Supports sustained sliding rather than primarily providing a walking platform like a snowshoe.
Has geometry and running-surface features whose interpretation depends on the skiing discipline; metal edges and a uniform smooth base are not mandatory recognition tests.
A runner integrated into a sled or vehicle is outside this model even if its shape resembles a ski.
Scope

+ Geometry, flex and construction of the ski body
+ Base, edges and directional grip features
+ Binding mounting interfaces and compatibility evidence
+ Individual ski condition, pair matching and service history
- Skiing as an activity, sport or occupational practice

- Ski poles, clothing and protective equipment
- Resort operations, route conditions and avalanche assessment
Characteristics
- Intended skiing discipline
- alpine downhill | cross-country | touring | jumping | other | unresolved; allow multiple declared uses Determines which geometry, grip, attachment and maintenance questions apply.
- Length and width profile
- length in cm; tip, waist and tail widths in mm; measurement method recorded Supports identification and assessment of suitability for the intended use.
- Longitudinal profile
- camber and rocker arrangement, with loaded or unloaded observation conditions Describes how the running surface may contact snow and how grip zones should be interpreted.
- Flex response
- force in N and deflection in mm under a recorded fixture and loading method Makes stiffness evidence interpretable without treating unrelated manufacturer ratings as equivalent.
- Mass per ski
- g; specify whether bindings, plates or skins are included Supports handling and touring assessments and meaningful comparisons.
- Running-surface configuration
- glide surface, waxable grip zone, patterned grip zone, integrated skin, detachable skin compatibility, or other documented configuration Determines which surface treatments and uphill-grip actions are applicable.
- Binding attachment interface
- linked mounting specification, plate or rail system, mounting position and approved attachment constraints Prevents inferring safe attachment from visual fit alone.
- Structural and surface condition
- observed defects by location, extent and inspection date; serviceability unresolved until assessed Separates damage observations from permission to use or repair the ski.
- Pair relationship
- paired ski identifier, matching evidence and any designated left/right orientation Allows mismatched geometry, flex, mounting or wear to be detected.

Ski identity and use Establishes the ski sense, discipline and intended operating context.
A ski's recognition and suitability depend on its intended sliding medium and discipline.
Sense and equipment boundary
Separates a foot-controlled ski from neighbouring sliding equipment.
Ski recognition
Record evidence that the object is a ski and identify any unresolved snow-ski or water-ski sense.
- Is this equipment intended to support a user's foot during longitudinal sliding, and on which medium? definition
- What separates this entry from a snowboard, snowshoe or vehicle runner? boundary
Discipline and suitability
Connects the ski's declared use to terrain, movement and user requirements.
Declared use envelope
Record intended disciplines and the evidence needed before judging suitability for a particular skier.
- Which disciplines and snow or terrain conditions does the manufacturer identify for this ski? provenance
- Which user mass, ability, load and intended-movement criteria must be checked before recommending this ski? action
Geometry and load response Describes the ski's dimensions, snow-contact profile and deformation under load.
Length alone cannot characterise a ski's support, grip or turning behaviour.
Planform and contact profile
Records width distribution, sidecut and camber or rocker.
Measured ski shape
Keep nominal dimensions distinct from measurements and retain the conditions used to observe snow-contact geometry.
- What are the ski's length and tip, waist and tail widths, and how were they measured? measurement
- What camber or rocker arrangement is present, and was it observed loaded or unloaded? measurement
Construction and flex
Connects documented construction with longitudinal and torsional response.
Load response evidence
Record construction claims and flex evidence without inferring internal materials from appearance.
- Which core, reinforcement and body-construction details are supported by product documentation? provenance
- What loading method and result describe longitudinal flex or torsional response, and are paired skis comparable? measurement
Snow contact and traction Models the surfaces that provide glide, directional control and resistance to backward sliding.
Different skis require different treatment of glide zones, grip zones, edges and skins.
Base and edge behaviour
Identifies running-surface zones and edge configurations before servicing them.
Glide and edge configuration
Record the base and edge arrangement, including whether metal edges exist and which treatment instructions apply.
- Which parts of the base are intended for glide, and what edge materials and coverage are documented? definition
- Which waxing, grinding or edge-tuning procedures are permitted for this ski's construction? action
Kick and climbing grip
Distinguishes built-in traction from removable climbing equipment.
Grip system and transition
Record how uphill or kick-phase traction is provided and which changes are needed between movement modes.
- Does the ski use grip wax, a patterned zone, an integrated skin, detachable skins or no dedicated grip feature? definition
- Which cleaning, treatment, attachment or removal steps apply before changing between climbing and gliding? action
Attachment, condition and service Connects the boot-binding attachment chain with ski integrity and maintenance decisions.
A sound running surface does not establish that a ski is correctly mounted, structurally intact or ready for use.
Binding interface and pairing
Records mounting constraints and the relationship between skis used together.
Mounting compatibility
Locate the ski's contribution to attachment compatibility while leaving binding release and boot design to their own models.
- Which binding interfaces, mounting locations and attachment procedures are approved for this ski? provenance
- Which compatibility checks belong to the ski, and which require the linked boot and binding specifications? boundary
Pair consistency
Record whether the skis intended for use together have compatible dimensions, flex, orientation and mounting.
- What evidence establishes that these skis form an appropriate pair for the intended discipline? provenance
- Do their geometry, flex, mounting positions or designated orientations differ in ways requiring assessment? measurement
Damage and service decisions
Turns located observations and service records into bounded next actions.
Ski integrity assessment
Record base gouges, edge damage, delamination, deformation and mounting-area defects without assigning unsupported repair thresholds.
- Where are defects located, how extensive are they, and do they involve the running surface, structural body or binding attachment area? measurement
- Which documented inspection or repair criteria determine whether this ski can be serviced, requires specialist assessment or should be withdrawn from use? 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.

What the second pass must settle
- Does vr.tr.ski denote snow skis only, or does the registry intend to include water skis and other specialised senses?
- Does an existing world model already cover this concept, requiring a registry link instead of a separate publication?
- Which discipline-specific standards apply to ski bodies and mounting interfaces, who issues them, and which editions and applicability limits are current?
- Which authoritative sources establish dimension ranges and comparable flex measurements for each included ski discipline?
- Which manufacturer or service authorities provide defensible inspection, remounting, repair and retirement criteria for different ski constructions?
