Property ValueClass

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.

Properties from PropertyValue: Property Expected Type TMPC Mapping description
maxValue
Number
The upper value of some characteristic or property.
measurementTechnique
URL
Text
A technique or technology used in a Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (described using variableMeasured). This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but rather as a high level summary for dataset discovery.
For example, if variableMeasured is: molecule concentration, measurementTechnique could be: "mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence".
If the variableMeasured is "depression rating", the measurementTechnique could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory".
If there are several variableMeasured properties recorded for some given data object, use a PropertyValue for each variableMeasured and attach the corresponding measurementTechnique.
minValue
Number
The lower value of some characteristic or property.
propertyID
Text
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.
unitCode
Text
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.
unitText
Text
A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.
value
StructuredValue
Text
Boolean
Number
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'.\n Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.\n Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

Text
MeasurementTypeEnumeration QuantitativeValue
A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.
Properties from Thing: Property Expected Type TMPC Mapping description
additionalType
URL
An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
alternateName
Text
An alias for the item.
description
Text
A description of the item.
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.
identifier
PropertyValue
URL
Text
The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
image
URL
ImageObject
An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage
URL
CreativeWork
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
name
Text
The name of the item.
potentialAction
Action
Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs
URL
URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
subjectOf
Event CreativeWork
A CreativeWork or Event about this Thing.
url
URL
URL of the item.
Instances of PropertyValue may appear with as a value for the following properties: Property On Types TMPC Mapping description
additionalProperty
QuantitativeValue Place MerchantReturnPolicy Product QualitativeValue
A property-value pair representing an additional characteristic of the entity, e.g. a product feature or another characteristic for which there is no matching property in schema.org.\n\nNote: Publishers should be aware that applications designed to use specific schema.org properties (e.g. https://schema.org/width, https://schema.org/color, https://schema.org/gtin13, ...) will typically expect such data to be provided using those properties, rather than using the generic property/value mechanism.
associatedDisease
BioChemEntity
Disease associated to this BioChemEntity. Such disease can be a MedicalCondition or a URL. If you want to add an evidence supporting the association, please use PropertyValue.
exifData
ImageObject
exif data for this object.
hasMolecularFunction
BioChemEntity
Molecular function performed by this BioChemEntity; please use PropertyValue if you want to include any evidence.
hasRepresentation
BioChemEntity
A common representation such as a protein sequence or chemical structure for this entity. For images use schema.org/image.
identifier
Thing
The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
isInvolvedInBiologicalProcess
BioChemEntity
Biological process this BioChemEntity is involved in; please use PropertyValue if you want to include any evidence.
isLocatedInSubcellularLocation
BioChemEntity
Subcellular location where this BioChemEntity is located; please use PropertyValue if you want to include any evidence.
taxonRank
Taxon
The taxonomic rank of this taxon given preferably as a URI from a controlled vocabulary – typically the ranks from TDWG TaxonRank ontology or equivalent Wikidata URIs.
valueReference
QualitativeValue PropertyValue QuantitativeValue
A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.
variableMeasured
Dataset
The variableMeasured property can indicate (repeated as necessary) the variables that are measured in some dataset, either described as text or as pairs of identifier and description using PropertyValue.
