ConstraintNode
The ConstraintNode type is provided to support usecases in which a node in a structured data graph is described with properties which appear to describe a single entity, but are being used in a situation where they serve a more abstract purpose. A [[ConstraintNode]] can be described using [[constraintProperty]] and [[numConstraints]]. These constraint properties can serve a variety of purposes, and their values may sometimes be understood to indicate sets of possible values rather than single, exact and specific values.
Type Information
- Parent Type: Intangible

Properties
| Property | Expected Type | Description | |----------|---------------|-------------| | numConstraints | Integer | Indicates the number of constraints property values defined for a particular [[ConstraintNode]] such as [[StatisticalVariable]]. This helps applications understand if they have access to a sufficiently complete description of a [[StatisticalVariable]] or other construct that is defined using properties on template-style nodes. | | constraintProperty | URL or Property | Indicates a property used as a constraint. For example, in the definition of a [[StatisticalVariable]]. The value is a property, either from within Schema.org or from other compatible (e.g. RDF) systems such as DataCommons.org or Wikidata.org. |
Properties from Thing
| Property | Expected Type | Description | |----------|---------------|-------------| | digital | Number | A number from 0.0 to 1.0 representing the degree of digital vs physical embodiment. 1.0 = fully digital, 0.0 = fully physical, 0.5 = hybrid. | | 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. | | potentialAction | Action | Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role. | | 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. | | identifier | URL or Text or PropertyValue | 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]]. | | 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. | | description | Text or TextObject | A description of the item. | | alternateName | Text | An alias for the item. | | url | URL | URL of the item. | | subjectOf | Event or CreativeWork | A CreativeWork or Event about this Thing. | | name | Text | The name of the item. | | 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. |
