Entity definition

The resource type IfcCrewResourceType defines commonly shared information for occurrences of crew resources. The set of shared information may include:

It is used to define a crew resource specification (the specific resource information that is common to all occurrences of that resource). Resource types may be exchanged without being already assigned to occurrences.

Occurrences of the IfcCrewResourceType are represented by instances of IfcCrewResource.

HISTORY  New entity in IFC4.

IfcRoot
1GlobalIdIfcGloballyUniqueId[1:1] Assignment of a globally unique identifier within the entire software world. X
2OwnerHistoryIfcOwnerHistory[0:1] Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
NOTE  only the last modification in stored - either as addition, deletion or modification.
X
3NameIfcLabel[0:1] Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule. X
4DescriptionIfcText[0:1] Optional description, provided for exchanging informative comments.X
IfcObjectDefinition
HasAssignmentsIfcRelAssigns
@RelatedObjects		S[0:?]Reference to the relationship objects, that assign (by an association relationship) other subtypes of IfcObject to this object instance. Examples are the association to products, processes, controls, resources or groups.X
NestsIfcRelNests
@RelatedObjects		S[0:1]References to the decomposition relationship being a nesting. It determines that this object definition is a part within an ordered whole/part decomposition relationship. An object occurrence or type can only be part of a single decomposition (to allow hierarchical strutures only). X
IsNestedByIfcRelNests
@RelatingObject		S[0:?]References to the decomposition relationship being a nesting. It determines that this object definition is the whole within an ordered whole/part decomposition relationship. An object or object type can be nested by several other objects (occurrences or types). X
HasContextIfcRelDeclares
@RelatedDefinitions		S[0:1]References to the context providing context information such as project unit or representation context. It should only be asserted for the uppermost non-spatial object. X
IsDecomposedByIfcRelAggregates
@RelatingObject		S[0:?]References to the decomposition relationship being an aggregation. It determines that this object definition is whole within an unordered whole/part decomposition relationship. An object definitions can be aggregated by several other objects (occurrences or parts). X
DecomposesIfcRelAggregates
@RelatedObjects		S[0:1]References to the decomposition relationship being an aggregation. It determines that this object definition is a part within an unordered whole/part decomposition relationship. An object definitions can only be part of a single decomposition (to allow hierarchical strutures only). X
HasAssociationsIfcRelAssociates
@RelatedObjects		S[0:?]Reference to the relationship objects, that associates external references or other resource definitions to the object.. Examples are the association to library, documentation or classification.X
IfcTypeObject
5ApplicableOccurrenceIfcIdentifier[0:1] The attribute optionally defines the data type of the occurrence object, to which the assigned type object can relate. If not present, no instruction is given to which occurrence object the type object is applicable. The following conventions are used:
  • The IFC entity name of the applicable occurrence using the IFC naming convention, CamelCase with IFC prefix
  • It can be optionally followed by the predefined type after the separator "/" (forward slash), using uppercase
  • If one type object is applicable to many occurrence objects, then those occurrence object names should be separate by comma "," forming a comma separated string.
EXAMPLE Refering to a furniture as applicable occurrence entity would be expressed as 'IfcFurnishingElement', refering to a brace as applicable entity would be expressed as 'IfcMember/BRACE', refering to a wall and wall standard case would be expressed as 'IfcWall, IfcWallStandardCase'.
X
6HasPropertySetsIfcPropertySetDefinitionS[1:?] Set list of unique property sets, that are associated with the object type and are common to all object occurrences referring to this object type. X
TypesIfcRelDefinesByType
@RelatingType		S[0:1]Reference to the relationship IfcRelDefinedByType and thus to those occurrence objects, which are defined by this type.X
IfcTypeResource
7IdentificationIfcIdentifier[0:1] An identifying designation given to a resource type.X
8LongDescriptionIfcText[0:1] An long description, or text, describing the resource in detail.
NOTE  The inherited SELF\IfcRoot.Description attribute is used as the short description.
X
9ResourceTypeIfcLabel[0:1] 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. X
ResourceOfIfcRelAssignsToResource
@RelatingResource		S[0:?]Set of relationships to other objects, e.g. products, processes, controls, resources or actors to which this resource type is a resource. X
IfcConstructionResourceType
10BaseCostsIfcAppliedValueL[1:?] Indicates the unit costs and environmental impacts for which accrued amounts should be calculated. Such unit costs may be split into Name designations (e.g. 'Standard', 'Overtime'), and may contain a hierarchy of cost values that apply at different dates (using IfcCostValue.ApplicableDate and IfcCostValue.FixedUntilDate).

X
11BaseQuantityIfcPhysicalQuantity[0:1] Identifies the quantity for which the BaseQuantityProduced applies. The Name of the IfcPhysicalQuantity identifies the quantity definition being measured, e.g. "GrossVolume". For production-based resources (e.g. carpentry labor), this value refers to quantities on IfcProduct(s) to which the assigned IfcTask is assigned. For duration-based resources (e.g. safety inspector, fuel for equipment), this value refers to quantities that may be assigned to occurrences of the assigned IfcTaskType.
