Identity and naming Persistent POI identity and culturally qualified naming remain distinct.

Identity and represented feature

Keep POI identity, source listing ID and represented-feature identity separate. Similar names, shared coordinates and common addresses only suggest matches.

Persistent POI identity and reconciliation

Keep POI identity, source listing ID and represented-feature identity separate. Similar names, shared coordinates and common addresses only suggest matches.

Which master identifier and namespace identify this POI independently of the feature and source listings it describes? identity
What makes this a single POI subject rather than a catalogue, event, organization or moving asset? definition
Which evidence supports or rejects an asserted duplicate, split or successor relationship? validation

Names and language

Keep names, aliases, historic forms and display labels as attributed values. Display preference is not official status; language tags do not prove equivalence.

Localized labels and naming claims

Keep names, aliases, historic forms and display labels as attributed values. Display preference is not official status; language tags do not prove equivalence.

Which labels, languages and scripts describe the POI, including an explicit unnamed or unknown case? classification
What evidence and jurisdiction qualify any official-name claim? authority
How are former names, transliterations and disputed alternatives retained and selected for a requested language? temporal

Location and place context Spatial representations and approach references require explicit meaning and quality.

Spatial representation

Distinguish display point, entrance, extent and relative indoor anchor. Coordinate corrections need not create a new POI. Unknown geometry cannot silently become a fabricated coordinate.

Geometry roles and uncertainty

Distinguish display point, entrance, extent and relative indoor anchor. Coordinate corrections need not create a new POI. Unknown geometry cannot silently become a fabricated coordinate.

Which location representation is used for display, extent or arrival, and what CRS, axis order and level qualify it? spatial
How was each position observed or transformed, with what uncertainty and conditions? measurement
When must a geometry projection be refused because its role, coordinate system or accuracy is unsuitable? constraint

Place context and approach

Record typed containment, adjacency and address references without inferring legal occupancy, parcel rights or a traversable route. An entrance may have a distinct access profile from the POI.

Qualified spatial links and entrances

Record typed containment, adjacency and address references without inferring legal occupancy, parcel rights or a traversable route. An entrance may have a distinct access profile from the POI.

Which places, buildings, parcels or indoor spaces contain or adjoin this POI, according to which evidence? relationship
Which address, entrance or approach references serve each intended arrival context? composition
Which physical access restrictions or unknown conditions apply at each entrance independently of map visibility? access

Description and recognition Capabilities, categories and recognition evidence support discovery without guaranteeing use.

Categories and amenities

Use versioned category assertions and conditional amenities. A facility description does not execute a service, guarantee availability or confer permission.

Classification and possible visitor uses

Use versioned category assertions and conditional amenities. A facility description does not execute a service, guarantee availability or confer permission.

Which category scheme, version and terms classify this POI and what competing assignments remain? classification
What amenities or visitor activities are described, with which conditions, restrictions and applicability? requirement
Which unsupported accessibility, safety or service claims must remain unknown or be delegated to a qualified profile? exception

Recognition and observations

Identify signs, imagery and observation references without treating a matching label or image as proof of identity. Observations are time-bound and may be stale or conflicting.

Evidence for on-site recognition

Identify signs, imagery and observation references without treating a matching label or image as proof of identity. Observations are time-bound and may be stale or conflicting.

Which signs, images or landmarks help distinguish this POI from nearby or similarly named places? evidence
Who observed each recognition cue, when and by what method under which conditions? provenance
What changes or contradictory observations make the recognition evidence stale or unsafe to rely on? quality

Availability and change Schedules, observed availability and lifecycle changes have separate semantics.

Schedules and visitor availability

Separate recurring local hours from instants, exceptional closures and real-time availability. Missing schedules mean unknown. Natural landmarks need not have operator opening hours.

Qualified opening schedules and exceptions

Separate recurring local hours from instants, exceptional closures and real-time availability. Missing schedules mean unknown. Natural landmarks need not have operator opening hours.

What regular hours, local time zone and validity interval apply to the place or specific service? temporal
Which holiday, seasonal, overnight or temporary exceptions override a schedule, and with what precedence? exception
How does the evidence distinguish scheduled opening from observed availability, appointment-only use or unknown status? state

Lifecycle and temporal continuity

Separate feature existence, operational status and listing publication state. Closure does not erase a landmark; relocation or operator replacement needs an explicit identity decision.

POI existence, listing status and changes

Separate feature existence, operational status and listing publication state. Closure does not erase a landmark; relocation or operator replacement needs an explicit identity decision.

Which evidence distinguishes proposed, active, temporarily closed, ceased, historical and retired listing states? lifecycle
Which rename, relocation, closure or operator-change event affects the POI and what identity decision follows? event
What are the separate validity, observation and ingestion times for a changed assertion? temporal

Stewardship and evidence Accountable roles and assertion lineage support controlled review.

Stewardship and contacts

Keep catalogue custodian, contributor, place operator, property holder and naming authority separate. A contact channel or source attribution grants no update rights.

Role-qualified responsibility and update authority

Keep catalogue custodian, contributor, place operator, property holder and naming authority separate. A contact channel or source attribution grants no update rights.

Which role stewards the POI record and which separately referenced roles operate or hold rights in the place? ownership
What mandate permits each contributor to propose, review or approve a POI change? authority
Which contact details can be exposed for the stated purpose without exposing private resident or contributor data? privacy

Assertion provenance and review

Link assertions to sources, revisions and review decisions. A source identifier, digest or contributor role cannot establish factual accuracy.

Evidence lineage and competing assertions

Link assertions to sources, revisions and review decisions. A source identifier, digest or contributor role cannot establish factual accuracy.

Which source entity and derivation activity support each POI assertion? provenance
How are incompatible source values retained and a preferred projection selected without deleting the dispute? decision
What evidence age, completeness or verification threshold makes a POI assertion fit for its intended use? quality

Rights and exchange Rights-aware projections preserve limitations and external model boundaries.

Rights and controlled disclosure

Apply source-specific reuse rights and purpose-specific release decisions. Public discovery is a controlled projection; sensitivity can require suppression. Historical continuity does not require perpetual personal-data storage.

Licensing, sensitive locations and disposal

Which location or attachment details require restricted, generalized or suppressed views for each audience? security
Which licenses, attribution duties and source restrictions govern each reused description, geometry or image? requirement
What retention, correction and disposal rules govern POI assertions, evidence and generated views? retention

Profiles and interoperability

Bind a local profile before exporting. OGC conceptual alignment, vocabulary use and GeoJSON serialization require separate implementation checks. Missing mandatory target fields cause refusal, not invented values.

Loss-aware projections and acceptance

Which pinned target profile maps POI identity, geometry, payloads and provenance without conflating the represented feature? interoperability
Which acceptance fixtures test duplicate locations, unnamed places, uncertain geometry, overnight hours and restricted entrances? validation
What authority, current revision and validation evidence are required before preparing a recipient-scoped local export? process

What it is Filled

A persistent POI subject with its own identifier, source-qualified synopsis and references to independently mastered features. It is not a whole catalogue, an address register or the physical asset itself. A POI can describe an area, line or indoor location; the word point does not require point-only geometry. Multiple listings may describe the same feature without sharing record identity.

In scope

POI identity, localized labels, category assertions and represented-feature references
Location roles, geometry quality, entry context, observed recognition and qualified visitor information
Listing lifecycle, provenance, stewardship, rights, selective disclosure and proposed local projection operations

Out of scope

Address assignment, street naming, postal formatting, coordinate reference system definition and geocoding service execution
Building, parcel, indoor-space, organization, event and gazetteer master lifecycles
Route planning, real-time navigation, physical entry control, booking, payments, access certification and continuous tracking of moving persons or assets

Why it exists Filled

Describe one identifiable POI for discovery and orientation through qualified assertions about a place or represented feature.

Distinguishing features Derived, awaiting review

Unlike WM-XCT-010 Location Referencing / Address: Reference an address or location designation when available. No mandatory civic address and no address assignment or retirement powers are inherited from legacy U7.
Unlike WM-XCT-033 Geometry / Coordinate Reference: Keep POI-specific location role and observations; reference geometry and CRS definitions rather than owning transformation engines or reference-system registries.
Unlike WM-PLC-010 Gazetteer Place: A gazetteer entry is an external place/name authority. POI labels can be descriptive or unofficial; record disputed name assertions without adjudicating sovereignty.
Unlike WM-BLT-001, WM-BLT-002, WM-PLC-002 and WM-PLC-009: Building, premises, parcel and indoor-space references are optional candidate bindings. A POI synopsis and a represented feature have distinct identities and revision histories.
Unlike Legacy U7 Address and Location Referencing: Legacy material is reconciled as broad predecessor input. Only its POI identity, category, language, lifecycle and qualified geocode concerns survive locally. Address registrar authority and old conformance assertions are not inherited.

Note: Derived from boundary notes against neighbouring models.

What robots and AI may and may not do Derived, awaiting review

Must not

Restricted or dangerous facilities remain at policy-level description; refuse operational details that enable harm.
Deny undisclosed access by default.

Only with a human decision

Prefer role-based contact references and minimize person-linked data; review source rights before reproducing imagery or descriptions.

May

Resolve a qualified POI reference: Proposed operation, not implemented. Resolve an exact namespace and identifier; similarity may return candidates but never automatically merge identities.
Record a location assertion: Proposed operation, not implemented. Append qualified geometry or an unresolved location reason, preserving role, source and uncertainty.
Record availability evidence: Proposed operation, not implemented. Append schedule or observed availability evidence and distinguish recurring local time from actual observation.
Record an identity review: Proposed operation, not implemented. Record an authorized duplicate, relocation or successor decision with evidence and retained aliases.
Record a POI state assertion: Proposed operation, not implemented. Append closure, proposed, historical or retirement evidence with separate listing and represented-feature states.
Prepare a scoped POI projection: Proposed operation, not implemented. Create a local export under a pinned mapping and license/access decision, reporting every omitted or generalized field.

Note: Derived from functions, policies, CRUD and access rules; prohibitions were not authored for agents as such.

Moral aspects Derived, awaiting review

Select applicable privacy, naming, accessibility and licensing profiles before operation.
Public POI discovery does not authorize entry, navigation, surveillance or unrestricted distribution of precise sensitive locations.
Restricted or dangerous facilities remain at policy-level description; refuse operational details that enable harm.
Jurisdiction-specific naming, language selection, privacy, accessibility and source-license applicability need profile review.

Note: Sentences mentioning harm, privacy, consent or similar, collected from the specification.
