Class Node

A Class Node specifies the constraints for a class. Note that this kind of node has similarities to an Enumeration Node.

For sh:class arrays are allowed, these are supposed to represent multi-typed entities (MTE) and our verifier matches this MTEs only if the target entity has all the listed types (see the second example) or subtypes of the type(s) defined in sh:class.

If further restrictions are given for a type (e.g. its properties, which is always the expected case in semantify.it), then these are defined within a NodeShape. This NodeShape is wrapped by a sh:node attribute for the range node.

Example

{
  "sh:class": "schema:Airport",
  "sh:node": {
    "@type": "sh:NodeShape",
    "sh:property": [
      {
        "@type": "sh:PropertyShape",
        ...
      },
      ...
    ]
  }
}
,
{
  "sh:class": ["schema:HotelRoom", "schema:Product"],
  "sh:node": {
    "@type": "sh:NodeShape",
    "sh:property": [
      {
        "@type": "sh:PropertyShape",
        ...
      },
      ...
    ]
  }
}

Key-value table

key	required	value type	description	related error
sh:class	true	IRI / [ IRI ]	The IRI(s) of the Class(es) that the value (value must be an entity with @type) must have	Non-conform range
sh:node	false	NodeShape	Additional constraints for the properties of the value (value must be an entity with @type) are possible with a node shape. The NodeShape CAN have the key-property @type with the string value sh:NodeShape, and it MUST have the key-property sh:property with an Array of PropertyNodes as value	Missing Property, Non-conform property
