A property-value pair, e.g. representing a feature of a product or place. Use the 'name' property for the name of the property. If there is an additional human-readable version of the value, put that into the 'description' property.\n\n Always use specific schema.org properties when a) they exist and b) you can populate them. Using PropertyValue as a substitute will typically not trigger the same effect as using the original, specific property.
Свойство Ожидаемый тип Описание
Свойства от PropertyValue
unitCode Text
или URL
The unit of measurement given using the UN/CEFACT Common Code (3 characters) or a URL. Other codes than the UN/CEFACT Common Code may be used with a prefix followed by a colon.
valueReference Enumeration
или StructuredValue
или PropertyValue
или QualitativeValue
или QuantitativeValue
A pointer to a secondary value that provides additional information on the original value, e.g. a reference temperature.
unitText Text A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.
propertyID Text
или URL
A commonly used identifier for the characteristic represented by the property, e.g. a manufacturer or a standard code for a property. propertyID can be (1) a prefixed string, mainly meant to be used with standards for product properties; (2) a site-specific, non-prefixed string (e.g. the primary key of the property or the vendor-specific id of the property), or (3) a URL indicating the type of the property, either pointing to an external vocabulary, or a Web resource that describes the property (e.g. a glossary entry). Standards bodies should promote a standard prefix for the identifiers of properties from their standards.
maxValue Number The upper value of some characteristic or property.
minValue Number The lower value of some characteristic or property.
value Number
или Text
или Boolean
или StructuredValue
The value of the quantitative value or property value node.\n\n* For [[QuantitativeValue]] and [[MonetaryAmount]], the recommended type for values is 'Number'.\n* For [[PropertyValue]], it can be 'Text;', 'Number', 'Boolean', or 'StructuredValue'.
Свойства от Thing
additionalType URL Дополнительный тип для элемента, который обычно используется для добавления более конкретных типов от внешних словарей в синтаксис микроданных. Это отношения между чем-то и классом к которому он принадлежит. В синтаксисе RDFa, лучше использовать родной синтаксис RDF - аттрибут "TypeOf" для множественных типов. Инстументы Schema.org могут слабо понимать дополнительные типы, особенно те, которые определены извне.
alternateName Text Любое альтернативное название медицинской сущности.
description Text Короткое описание записи.
image URL
или ImageObject
URL изображения записи.
name Text Имя записи.
sameAs URL Адрес веб-страницы, которая недвусмысленно указывает на идентичность элемента. Например, ссылка на страницу элемента на Википедии, Freebase страницу или на официальный сайт.
url URL URL записи.
potentialAction Action Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
mainEntityOfPage CreativeWork
или URL
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details.
disambiguatingDescription Text A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
