Earring identity and configuration Establishes what constitutes this individual earring and which wearing configuration is being assessed.
Ear ornament identity
Records the evidence that the object is intended to function as an ear ornament.
Intended ear use
The agent needs an evidenced intended use and a form description rather than an identity inferred solely from appearance.
- What design feature or documentation establishes that this object is intended to be worn as an ear ornament? definition
- Is this a complete earring, an earring component or an object whose intended wearing location remains uncertain? boundary
Wearing assembly
Defines the components present in the configuration under consideration.
Required and optional parts
Completeness depends on the attachment design and any detachable decorative elements.
- Which backing, closure, pendant or adapter belongs to this wearing configuration? definition
- Which missing parts prevent attachment, and which only alter the intended appearance? boundary
Ear attachment and fit Captures how the earring meets the ear and the dimensions relevant to that interface.
Attachment interface
Describes the mechanism, intended placement and relevant contact geometry.
Mechanism and interface dimensions
The model must distinguish the attachment type from the measurements needed to assess a particular interface.
- How does this earring attach, and does that configuration require a piercing? definition
- What are the applicable post or wire diameter, usable length, opening and contact gap? measurement
Worn geometry and load
Records the size, movement and mass of the earring in its wearing configuration.
Drop, clearance and mass
Fit assessment needs the actual assembly's load and occupied space, including movable portions.
- What are the mass per earring, worn drop and maximum extent of any swinging or projecting elements? measurement
- What wearer-specific clearance or fit information is still needed before recommending this configuration? action
Contact materials and care Connects component-level material evidence with contact surfaces and supported care methods.
Contact surface evidence
Distinguishes known composition, surface finishes and unverified claims at the wearing interface.
Component material confidence
Material identification should record its evidence and apply only to the components that evidence covers.
- What evidence identifies the materials and finishes of the post, backing and other ear-contacting surfaces? provenance
- Does that evidence cover the complete assembly, or are some components or underlying materials unknown? boundary
Construction-sensitive care
Records care constraints associated with coatings, stones, adhesives and mixed construction.
Supported cleaning method
Cleaning recommendations need evidence applicable to the assembled earring, including its least-understood component.
- Which maker instructions or other applicable evidence support a cleaning method for this earring's materials and construction? provenance
- What care action is supported now, and which action requires further material or construction identification? action
Retention and structural condition Assesses the mechanisms and connections that keep the earring attached and its ornamentation intact.
Fastener function
Records closure engagement and defects in the ear attachment mechanism.
Closure engagement evidence
A functional assessment must identify the check performed and avoid overstating what it establishes.
- What inspection or non-damaging functional check has established whether the backing, clip, hinge or latch engages? provenance
- Does observed looseness, jamming, deformation or incomplete engagement require repair or further assessment before wear? action
Ornament and joint integrity
Locates damage or instability in settings, suspended parts and their connections.
Settings, joints and edges
Condition needs to be recorded at the affected feature so that handling and repair decisions address the actual defect.
- Where are there loose stones, open connecting rings, cracked joints, bent posts or sharp exposed edges? measurement
- Which observed defects justify setting the earring aside, securing a detachable part or referring it for repair? action
Pairing and component compatibility Establishes matching relationships and whether detachable parts belong with this individual earring.
Counterpart and orientation
Records pair membership, intentional differences and any wearing orientation.
Matching counterpart
A counterpart may be identical, mirrored or intentionally different, so the intended relationship needs evidence.
- What evidence links this earring to its proposed counterpart or set? provenance
- Is the design interchangeable between ears, handed or intentionally mismatched? definition
Detachable part fit
Records compatibility of replacement backings, charms and adapters.
Replacement interface compatibility
Replacement decisions require evidence about the relevant interface and retention, not just matching colour or style.
- What dimensions, thread details or maker specifications establish compatibility with the proposed replacement part? measurement
- What fit and retention checks remain necessary before the replacement can be treated as usable? action

What it is Filled
A jewellery article worn on the external ear (earlobe or pinna), retained by a piercing post or wire, a hinged or latch closure, a clip or screw that compresses unpierced tissue, or a cuff that grips cartilage, and typically made of a fastening plus one or more ornamental elements.
In scope
- Identification of the individual earring and its intended ear placement
- Pierced and non-pierced attachment mechanisms and their retained components
- Dimensions, mass and geometry relevant to wearing and handling
- Materials, finishes and evidence about surfaces that contact the wearer
- Structural condition, fastening function and care constraints
- Pair membership, handedness and compatibility with replacement components
Out of scope
- The wearer's ear anatomy, piercing condition and clinical care

Why it exists Filled
Enable an AI agent to recognise an earring, assess its attachment, condition and suitability for an intended use, and determine appropriate handling or maintenance actions.
Distinguishing features Filled
- Its design or documented intended use identifies the ear as its wearing location; merely being small and decorative is insufficient.
- It has an ear attachment arrangement, such as a post, hook, closing hoop, clip, cuff or another evidenced mechanism.
- A loose backing, charm or post is a component rather than a complete earring unless an identified assembly establishes its role.
- A matching pair contains two individual earrings; one remaining member is still an earring.
- For objects resembling general body jewellery or hearing accessories, intended ear-ornament use must be established rather than inferred from shape alone.
What robots and AI may and may not do Filled
Must not
- Pierce someone's ear or advise piercing a child without the consent of the person or their guardians.
- Sell earrings under false claims about metal, gemstones or being hypoallergenic.
- Advise wearing hoop or dangling earrings where they can catch in machinery or contact sports.
- Remove an earring from a person without their consent.
Only with a human decision
- Piercing or treating an infected piercing on a child.
May
- Describe earring types, closures and materials.
- Advise users on caring for earrings and keeping piercings clean, citing health sources.
Moral aspects Filled
- Earrings carry cultural, religious and gender identity; mocking or banning them can hurt dignity.
- Metal allergies and infections harm people who trusted product claims.
Who is affected
- Wearers
- Children
- Buyers
