5.1.3.47 IfcTypeProcess

ABSTRACT This definition may not be instantiated

5.1.3.47.1 Semantic definition

IfcTypeProcess defines a specific (or type) definition of a process or activity without being assigned to a schedule or a time.聽It is used to define a process or activity specification, that is, the specific process or activity information that is common to all occurrences that are defined for that process or activity type.

An IfcTypeProcess may have a list of property set attached. Values of these properties are common to all occurrences of that process or activity type. The type occurrence relationship is realized using the objectified relationship IfcRelDefinesByType.

Subtypes of IfcTypeProcess may be exchanged without being already assigned to subtypes of IfcProcess.

5.1.3.47.3 Attributes

# Attribute Type Description
IfcRoot (4)
1 GlobalId IfcGloballyUniqueId

Assignment of a globally unique identifier within the entire software world.

2 OwnerHistory OPTIONAL IfcOwnerHistory

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,

3 Name OPTIONAL IfcLabel

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.

4 Description OPTIONAL IfcText

Optional description, provided for exchanging informative comments.

IfcObjectDefinition (7)
HasAssignments SET [0:?] OF IfcRelAssigns FOR RelatedObjects

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.

Nests SET [0:1] OF IfcRelNests FOR RelatedObjects

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).

IsNestedBy SET [0:?] OF IfcRelNests FOR RelatingObject

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).

HasContext SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions

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.

IsDecomposedBy SET [0:?] OF IfcRelAggregates FOR RelatingObject

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).

Decomposes SET [0:1] OF IfcRelAggregates FOR RelatedObjects

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).

HasAssociations SET [0:?] OF IfcRelAssociates FOR RelatedObjects

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.

IfcTypeObject (3)
5 ApplicableOccurrence OPTIONAL IfcIdentifier

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.

6 HasPropertySets OPTIONAL SET [1:?] OF IfcPropertySetDefinition

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.

Types SET [0:1] OF IfcRelDefinesByType FOR RelatingType

Reference to the relationship IfcRelDefinedByType and thus to those occurrence objects, which are defined by this type.

IfcTypeProcess (4)
7 Identification OPTIONAL IfcIdentifier

An identifying designation given to a process type.

8 LongDescription OPTIONAL IfcText

An long description, or text, describing the activity in detail.

9 ProcessType OPTIONAL IfcLabel

The type denotes a particular type that indicates the process 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.

OperatesOn SET [0:?] OF IfcRelAssignsToProcess FOR RelatingProcess

Set of relationships to other objects, e.g. products, processes, controls, resources or actors that are operated on by the process type.
