Arrow identity and boundary Establishes what the object is and whether it belongs within the registered arrow concept.
Projectile identification
Separates bow-projectile identity from appearance and present usability.
Intended launch system
Record evidence of the intended launcher and distinguish original function from the object's current role.
- What marking, documentation, construction evidence or provenance identifies this as a bow-launched arrow? definition
- Is the object a functional projectile, unfinished assembly, replica, display item or historical artefact? boundary
Whole-arrow boundary
Determines whether the record concerns an arrow, its remains or a separate component.
Assembly identity
Record which parts constitute this arrow and whether missing or replaced parts affect its identification.
- Which shaft, front-end and rear-end components are present, absent or detached? definition
- Is this an identifiable incomplete arrow or a standalone component that belongs in a neighbouring model? boundary
Shaft and mass profile Captures the arrow's physical configuration through explicitly defined measurements.
Shaft geometry and stiffness
Records shaft construction and dimensions together with the conventions needed to interpret them.
Interpretable shaft specification
Keep observed dimensions, manufacturer designations and stiffness measurements distinguishable.
- What are the shaft material, construction, length and diameter profile, and where were the measurements taken? measurement
- What source or test convention defines the recorded spine or stiffness value? provenance
Assembled mass and balance
Connects mass and balance measurements to the installed component configuration.
Configuration-specific mass profile
Record total mass and balance location for a named assembly rather than treating them as permanent shaft properties.
- What is the measured total mass, in which unit, and with which components installed? measurement
- Where is the balance point relative to a stated datum, and does that measurement reflect the current assembly? measurement
Point, nock and fletching Describes the arrow's front and rear interfaces and the integrity of their attachments.
Front-end assembly
Records the point and any mounting components as an installed combination.
Point fit and retention
Capture point identity, mounting method, attachment condition and configuration-specific handling requirements.
- What point and mounting components are installed, and what evidence supports their fit to this shaft? provenance
- What inspection establishes whether the point assembly is secure, damaged or incomplete? action
Rear-end assembly
Records the string-engagement interface and any fletching arrangement.
Nock and fletching integrity
Record rear-component type, orientation, attachment and observed defects without assuming that all arrows share one arrangement.
- What nock or other string interface and fletching arrangement does this arrow have? definition
- Are rear components loose, cracked, distorted, missing or displaced relative to their documented configuration? measurement
Bow and use compatibility Assesses the arrow against an identified launcher setup and intended application.
Specified bow pairing
Makes compatibility an evidenced relationship to a particular bow configuration.
Pairing evidence
Record applicable compatibility guidance and the arrow and bow facts needed to apply it.
- Which bow setup is being assessed, including the relevant draw conditions, string interface and arrow support? boundary
- What applicable guidance supports the pairing, and which required arrow or bow measurements remain unknown? provenance
Intended-use fit
Connects the installed arrow configuration to a specific proposed use.
Use-dependent restrictions
Record whether the point and overall arrow configuration meet requirements supplied by the intended activity and target context.
- What use is proposed, and what requirements does it impose on this arrow's point and assembly? boundary
- Does the available evidence support that use, require a configuration change or leave the decision unresolved? action
Damage history and disposition Connects arrow-specific damage observations, relevant events and maintenance to the next permitted action.
Shaft damage assessment
Records material-appropriate inspection evidence and its limits.
Observed defects and inspection coverage
Locate observed shaft defects and distinguish inspected areas from unknown internal or obscured condition.
- What bends, cracks, splits, splinters, dents or other irregularities are observed, and where along the shaft? measurement
- Which inspection method is applicable to this shaft construction, and what condition can that method leave unresolved? action
Event-triggered reassessment
Tracks events that may change condition or invalidate recorded configuration and compatibility.
Maintenance and use disposition
Record relevant impacts, recovery, repairs and component changes, then assign a supported handling or use decision.
- What impacts, difficult extractions, storage exposures, repairs or component replacements occurred since the last assessment? provenance
- Should the arrow be inspected, maintained, stored with restrictions, accepted for specified use or retired, and what evidence supports that decision? action
- Which measurements and compatibility assessments must be repeated after the recorded change? action

What it is Filled
This model owns the identity, construction, configuration, condition and use constraints of an individual physical arrow, provisionally interpreted as a bow-launched projectile pending clarification of the registry boundary.
In scope
- The assembled arrow and the relationship between its shaft, point, nock and any fletching
- Arrow dimensions, mass, shaft stiffness and balance relevant to identification and compatibility
- Compatibility evidence linking the arrow configuration to a specified bow and intended use
- Component damage, attachment integrity, repair history and inspection status
- Handling, storage, maintenance and use restrictions arising from the arrow's configuration and condition
Out of scope
- Bow construction, adjustment and mechanical condition
- Archer technique, proficiency and personal suitability
- Targets, backstops and shooting-range operation
- Quivers, cases and other storage equipment as independently managed objects
- Directional symbols, diagram arrows and software pointer icons
- Legal permission for hunting or other activities involving arrows
Why it exists Filled
Enable an AI agent to recognise a physical arrow, assess its condition and compatibility, and decide whether it may be handled, maintained, stored or used with a specified bow.
Distinguishing features Filled
- Evidence identifies the object as a projectile intended for launch from a bow, rather than merely a pointed rod or an arrow-shaped ornament.
- The rear interface is intended to engage a bowstring; record absent, unusual or damaged interfaces rather than treating a familiar nock shape as mandatory.
- The shaft, front-end assembly and rear-end assembly form or formerly formed one projectile, distinguishing an arrow from an unattached arrowhead or replacement shaft.
- Launch-system identification distinguishes bow arrows from crossbow bolts, darts and thrown spears; appearance alone leaves ambiguous cases unresolved.
What robots and AI may and may not do Filled
Must not
- Assist in using arrows to injure people or to take animals outside lawful hunting.
- Advise shooting an arrow where people or animals may be beyond the target.
- Declare a cracked or damaged arrow safe to shoot.
- Help anyone evade hunting or weapon laws on bows and arrows.
Only with a human decision
- Approving arrows and broadheads for a hunt.
- Clearing a range for shooting when people are downrange.
May
- Describe an arrow's parts, spine, length and condition for its owner or a range officer.
- Report damaged or cracked arrows so they are taken out of use.
- Explain safe range conduct and equipment rules for archery as a sport.
Moral aspects Filled
- An arrow is a weapon as well as sports gear; its use must stay within safe and lawful bounds.
- Hunting with arrows raises questions of animal suffering and clean kills.
Who is affected
- Archers
- People near ranges
- Hunted animals
Owners Filled
Steward
The archer who owns it; clubs and range operators set the local rules.

Open questions
- Does vr.tr.arrow include crossbow bolts and specialised bow projectiles, or do authoritative neighbouring registry entries own them?
- Does an existing Vercy world model already own the physical-arrow concept, requiring a registry link instead of a separate publication?
- Which recognised measurement conventions should govern arrow length, spine and balance across different manufacturers and traditions?
- Which authoritative construction-specific guidance establishes inspection methods, repair limits and retirement criteria?
- How should incomplete arrows, replicas and historical artefacts retain arrow identity while receiving different use and preservation constraints?
