Entity Attributes Properties turn identity into a usable model.
An entity is more than a name. Attributes describe properties directly assigned to the entity, while related entities, offers and relationship states should remain distinguishable from intrinsic or literal-valued properties.
Strong entity modeling connects each property to an appropriate value or entity, preserves qualifiers such as unit, time, market and variant where they matter, and keeps the supporting evidence traceable.
Attributes describe properties of an entity.
An attribute associates an entity with a characteristic or value. Depending on the modeling system, a property may point to a literal value such as a date, number or text string, or to another entity. This page uses “attribute” primarily for descriptive or literal-valued properties and treats entity-to-entity edges as relationships so the two analytical layers stay distinct.
A property assigned to a specific entity.
The property should be semantically appropriate to the entity type, and its object—whether a literal value or another entity—should be represented with enough context to be interpreted correctly.
Different entity types require different property models.
Select an entity class. The lab changes the expected property set, a high-value distinguishing field, a time-sensitive or related state, and the main modeling risk. The examples are conceptual, not one vendor’s schema.
Organizations are described through stable identity properties plus operational, geographic and temporal fields.
Identity attributes should refer to the same organization users see on the page and should be updated when legal, contact or organizational facts change.
Not every property behaves the same way.
A robust entity model separates attributes by function and volatility. Stable identity facts should not be treated like prices, availability, statuses or derived values that can change rapidly.
Identity
Canonical name, legal name, identifier, model number or other properties that anchor the entity record.
LOW VOLATILITYDescriptive
Color, material, category, profession, language, genre or other characteristics that describe the object.
CONTEXTUALQuantitative
Height, weight, capacity, dimensions, speed, count or other measurable entity values with explicit units. Commercial price is usually better modeled on an Offer.
VALUE + UNITTemporal
Founding date, release date, start time, tenure period or another fact whose interpretation depends on time.
TIME BOUNDGeographic
Address, coordinates, country, region or spatial scope associated with the entity.
LOCATION SCOPEState / Status
Availability, operating status, condition, occupancy or another value that can change while the entity remains the same.
HIGH VOLATILITYDerived
A value calculated from other facts, such as duration, density, ratio or aggregate measurement. It should expose its basis when important.
CALCULATEDEvidence Metadata
Source, measurement method, effective date and evidence context describe the property assertion rather than the entity itself.
PROVENANCE LAYERThe entity type determines which attributes make sense.
Attributes are not interchangeable across entity classes. Keep literal or descriptive properties separate from entity-valued relations and from related commercial objects such as Offers. The distinction prevents a product price, an author relation or an event venue from being mistaken for an intrinsic scalar property.
Organization
Names, identifiers, address, contact channels, founding facts and organizational status.
EXAMPLES / legalName · url · address · taxID · telephoneProduct
Model, identifiers, color, material, dimensions, weight and technical specifications can describe the product itself. Brand can be an entity-valued relation; price and availability normally describe an Offer.
ATTRIBUTES / sku · gtin · color · material · dimensions · weightPerson
Name, credentials, birth-related facts and other appropriate biographical properties can describe a person. Employer or affiliation is usually an entity-to-entity relation, and roles may be time-bounded.
ATTRIBUTES / name · credential · birthDate · jobTitlePlace
Address, coordinates, elevation, timezone and other spatial properties can describe a place. Containment may also be represented as a relation to a region or administrative entity.
ATTRIBUTES / address · latitude · longitude · elevation · timezoneCreative Work
Title, publication or release date, language, edition, duration and encoding format can describe a work. Creator or author is an entity-valued relation.
ATTRIBUTES / name · datePublished · inLanguage · encodingFormatEvent
Name, start and end time, status and attendance mode can describe event state. Venue, organizer and performers are entity-valued relations.
ATTRIBUTES / startDate · endDate · eventStatus · eventAttendanceModeLiteral values describe the entity. Entity-valued properties create relations.
In RDF-style and Schema.org models, both can be expressed with properties or predicates. The analytical distinction here is the object type: a literal or measured value versus another independently identifiable entity.
The property points to a measured value. The value may carry a unit and qualifier, but it is not normally treated as an independently identified entity.
(Product X, weight, 1.4 kg)The object is another independently identifiable entity. This creates a graph edge and belongs primarily to the relationship layer of this research cluster.
(Company X) — founded by → (Person Y)A value is more auditable when its source and scope are known.
Attributes can be wrong even when the entity is correctly identified. Provenance, measurement method, effective date, unit and variant scope help prevent a value from being interpreted outside the conditions under which it is valid.
Some facts describe a moment, not eternity.
Temporal qualification applies across several layers: an address or event status may be an entity property, a leadership role is a time-bounded relationship, and price or availability normally belongs to an Offer. Keeping those scopes explicit prevents stale states from being mistaken for timeless entity facts.
Conflicting values require evidence, not averaging.
When different sources assign different values to the same attribute, the system needs to evaluate freshness, source role and directness, measurement method, scope and whether the values describe different variants, configurations or time periods.
Check whether the facts describe the same entity state.
A conflict may disappear after examining model variant, measurement method, publication date or market configuration.
- 01 / VERSION — same model or different revision?
- 02 / DATE — which value is current?
- 03 / UNIT — are units and conversions consistent?
- 04 / SCOPE — base configuration or accessory included?
- 05 / SOURCE — primary specification or copied secondary value?
Missing, unknown and not applicable are not equivalent.
Semantic models become unreliable when absence is silently converted into a false zero, placeholder or guessed value. The state of the information is itself meaningful.
The attribute has an explicit, usable value with appropriate context and evidence.
Missing data describes the state of the record, not proof that the real-world value is zero, false or nonexistent.
The property may apply, but available evidence is insufficient to assign a defensible value.
Forcing irrelevant attributes can create a noisier and less coherent entity representation.
Structured data can expose explicit property-value fields.
Google Search documents supported structured-data properties for specific Search features. Product identity fields belong on Product, while seller price and availability are represented on a nested Offer. The example below is educational and must be replaced with real, page-matching values before production use.
{ "@context": "https://schema.org/", "@type": "Product", "name": "Example Product X", "brand": { "@type": "Brand", "name": "Example Labs" }, "sku": "X100", "gtin14": "00012345600012", "offers": { "@type": "Offer", "price": 249.00, "priceCurrency": "EUR", "availability": "https://schema.org/InStock" } }
Names and product identifiers describe which Product node the page represents. Google recommends using the most specific GTIN property that applies when a valid GTIN exists.
The brand may itself be represented as another entity rather than a plain descriptive value.
These values belong to the nested Offer in this example and can change by seller, market or time.
Do not invent or expose unsupported property values simply to make the entity appear more complete.
Attributes create a semantic fingerprint.
A cluster of compatible properties can make an entity easier to understand and distinguish. The fingerprint becomes stronger when values are coherent, typed and supported rather than merely numerous.
Entity descriptions fail when properties lose context.
Attribute quality is not about filling every possible field. It is about assigning the right property to the right entity with a truthful value, appropriate scope and current evidence.
Attributes can make property-level evidence easier to interpret.
Property-level questions often depend on values such as price, size, date, location, compatibility or status. Clear entity binding, scope and qualifiers can reduce ambiguity when a system or reader interprets retrieved evidence, but they do not guarantee retrieval or answer correctness.
The retrieval task targets a specific property of an already identified entity.
ENTITY = Product X / ATTRIBUTE = weightThe answer is stronger when the value carries the correct unit, variant scope and source context.
VALUE + QUALIFIER + EVIDENCEMore fields do not create a better entity model.
Attribute selection should reflect identity value, distinguishing power, user utility, volatility and evidence quality. This is an internal evaluation model, not a search-engine metric.
A naked number is not enough. Preserve the conditions that make it true.
Quantitative and dynamic attributes become interpretable only when their entity binding, unit, variant, market, time and evidence context are preserved where those qualifiers materially affect meaning.
The right value attached to the wrong variant is still wrong.
Product families, editions, configurations, locations and time-bound states can share many attributes. Robust modeling keeps the subject boundary explicit so properties are not inherited across entities without evidence.
Properties common to the entire product family or organization belong at the parent level only when they genuinely apply to every relevant child.
FAMILY SCOPEColor, dimensions, storage, engine, finish or configuration can distinguish one variant from another.
VARIANT SCOPESeller, price, availability and commercial terms belong to an Offer or seller-specific commercial state rather than to immutable product identity.
OFFER SCOPEA role, address, price or status may be correct for one period and stale for another.
TIME SCOPEDo not copy a parent, sibling or previous-version property onto the current entity merely because the records are closely related.
VERIFY SUBJECTAudit the property system, not the keyword count.
The audit asks whether the page provides an appropriate, coherent and maintainable attribute model for the entity it represents.
Ground attributes in documented data models.
These primary sources support different parts of the page and should not be conflated. Google Cloud Natural Language documents entity-analysis output; Google Search documents Organization and Product structured data for Search features; Merchant API documents merchant product fields. None of these sources establishes a public Google Search “Entity Attributes score” or a universal entity-property ontology.
