ConstraintNode
schema.org/ConstraintNodeThe 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.

mainEntityOfPageIndicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. | CreativeWork · URL | Standard du web |
nameLe nom de l'élément. Pour un produit, le nom commercial tel qu'affiché sur la page. | Text | Standard du web |
potentialActionIndicates a potential Action, which describes an idealized action in which this thing would play an 'object' role. | Action | Standard du web |

constraintPropertyIndicates 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. | Property · URL | Rare |
numConstraintsIndicates 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. | Integer | Rare |
