Check for open issues.

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.

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.

Property	Expected Type	Description
Properties from PropertyValue
`maxValue`	Number	The upper value of some characteristic or property.
`measurementMethod`	DefinedTerm or MeasurementMethodEnum or Text or URL	A subproperty of measurementTechnique that can be used for specifying specific methods, in particular via MeasurementMethodEnum.
`measurementTechnique`	DefinedTerm or MeasurementMethodEnum or Text or URL	A technique, method or technology used in an Observation, StatisticalVariable or Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (for datasets, described using variableMeasured; for Observation, a StatisticalVariable). Often but not necessarily each variableMeasured will have an explicit representation as (or mapping to) an property such as those defined in Schema.org, or other RDF vocabularies and "knowledge graphs". In that case the subproperty of variableMeasured called measuredProperty is applicable. The measurementTechnique property helps when extra clarification is needed about how a measuredProperty was measured. 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 can often serve 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. The value can also be from an enumeration, organized as a MeasurementMetholdEnumeration.
`minValue`	Number	The lower value of some characteristic or property.
`propertyID`	Text or 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 or 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`	Boolean or Number or StructuredValue or Text	The value of a QuantitativeValue (including Observation) or property value node. For QuantitativeValue and MonetaryAmount, the recommended type for values is 'Number'. For PropertyValue, it can be 'Text', 'Number', 'Boolean', or 'StructuredValue'. Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols. Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
`valueReference`	DefinedTerm or Enumeration or MeasurementTypeEnumeration or PropertyValue or QualitativeValue or QuantitativeValue or StructuredValue or Text	A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.
Properties from Thing
`additionalType`	Text or 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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.
`alternateName`	Text	An alias for the item.
`description`	Text or TextObject	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 or Text or URL	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`	ImageObject or URL	An image of the item. This can be a URL or a fully described ImageObject.
`mainEntityOfPage`	CreativeWork or URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. Inverse property: mainEntity
`name`	Text	The name of the item.
`owner`	Organization or Person	A person or organization who owns this Thing. Inverse property: owns
`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`	CreativeWork or Event	A CreativeWork or Event about this Thing. Inverse property: about
`url`	URL	URL of the item.

Instances of PropertyValue may appear as a value for the following properties

Property	On Types	Description
additionalProperty	MerchantReturnPolicy or Offer or Place or Product or QualitativeValue or QuantitativeValue	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. Note: 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.
recipeIngredient	Recipe	An ingredient or ordered list of ingredients and potentially quantities used in the recipe, e.g. 1 cup of sugar, flour or garlic. The ingredients can be represented as free text or more structured values.
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	PropertyValue or QualitativeValue or QuantitativeValue	A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.
variableMeasured	Dataset or Observation	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, or more explicitly as a StatisticalVariable.
variablesMeasured	Dataset	Originally named variablesMeasured, 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.
