|Définition d'un type de ressource|
|Ressource (allgemein) - Typ|
IfcTypeResource defines a specific (or type) definition of a resource. It is used to define a resource specification (the specific resource, that is common to all occurrences that are defined for that resource) and could act as a resource template.
An IfcTypeResource may have a list of property sets attached. Values of these properties are common to all occurrences of that resource type. The type occurrence relationship is realized using the objectified relationship IfcRelDefinesByType.
Subtypes of IfcTypeResource may be exchanged without being already assigned to subtypes of IfcResource.
HISTORY New entity in IFC4.
Property set use definition
An IfcTypeResource may have a list of property sets attached, accessible by the attribute SELF\IfcTypeObject.HasPropertySets. Currently there are no predefined property sets defined as part of the IFC specification.
NOTE For property sets, a property within an occurrence property set that is assigned at the resource occurrence, overrides the same property assigned to the resource type.
XSD Specification: <xs:element name="IfcTypeResource" type="ifc:IfcTypeResource" abstract="true" substitutionGroup="ifc:IfcTypeObject" nillable="true"/>
<xs:complexType name="IfcTypeResource" abstract="true">
<xs:attribute name="Identification" type="ifc:IfcIdentifier" use="optional"/>
<xs:attribute name="LongDescription" type="ifc:IfcText" use="optional"/>
<xs:attribute name="ResourceType" type="ifc:IfcLabel" use="optional"/>
|Identification|| : ||
An identifying designation given to a resource type.
|LongDescription|| : ||
An long description, or text, describing the resource in detail.
NOTE The inherited SELF\IfcRoot.Description attribute is used as the short description.
|ResourceType|| : ||
The type denotes a particular type that indicates the resource further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute 'PredefinedType' is set to USERDEFINED.
|ResourceOf|| : ||
Set of relationships to other objects, e.g. products, processes, controls, resources or actors to which this resource type is a resource.
HISTORY New inverse relationship in IFC4.
