Analytical (Analytical) Schema

Alias: anlyt

Version: 1.0.1

The BIS classes that specialized Analytical domain schemas extend.

Contains the core classes which define the base classes used by specialized BIS Analytical Domain schemas, such as Hydraulic analysis, Structural analysis, Thermal analysis, etc. This schema is not meant to cover Analytical Results or Scenario Analysis, which will be addressed separately in the future.

Each specialized BIS Analytical Domain is expected to introduce subclasses for anlyt:AnalyticalPartition, anlyt:AnalyticalModel, anlyt:AnalyticalElement and, if needed, anlyt:AnalyticalType.

AnalyticalElement (Analytical Element) Abstract EntityClass

An anlyt:AnalyticalElement is spatially located, simulating zero or more bis:SpatialLocationElement or bis:PhysicalElement instances in light of a specialized analytical perspective.

Base Class: BisCore:GeometricElement3d

anlyt:AnalyticalElement is expected to be subclassed by specialized BIS Analytical Domain schemas.

AnalyticalModel (Analytical Model) Abstract EntityClass

A container for persisting anlyt:AnalyticalElement instances used to model a specialized analytical perspective.

Base Class: BisCore:GeometricModel3d

Inherited properties
Name Description Type Extended Type
ParentModel The parent bis:Model contains the bis:Element that this bis:Model is sub-modeling. navigation
ModeledElement The bis:Element that this bis:Model is sub-modeling. This bis:Model models the same Entity as the sub-Modeled bis:Element, but at a finer granularity. navigation

LastMod The last time any element in this Model was modified. dateTime
GeometryGuid A GUID that changes whenever any element in this GeometricModel has a change to its geometry. binary BeGuid
IsNotSpatiallyLocated If IsNotSpatiallyLocated is true, then the elements in this bis:GeometricModel3d are not in real-world coordinates and will not be in the spatial index. boolean
IsPlanProjection If IsPlanProjection is true, then the elements in this bis:GeometricModel3d are expected to be in an XY plane. boolean

anlyt:AnalyticalModel is expected to be subclassed by specialized BIS Analytical Domain schemas.

AnalyticalPartition (Analytical Partition) Abstract EntityClass

An anlyt:AnalyticalPartition element indicates that there is a specialized analytical perspective within the overall information hierarchy. An anlyt:AnalyticalPartition subclass is always parented to a bis:Subject and broken down by an anlyt:AnalyticalModel.

anlyt:AnalyticalPartition is expected to be subclassed by specialized BIS Analytical Domain schemas.

AnalyticalType (Analytical Type) Abstract EntityClass

Defines a shared set of properties (the 'type') that can be associated with an anlyt:AnalyticalElement. It is not meant to replace a bis:PhysicalType if it is available.

anlyt:AnalyticalType can be optionally subclassed by specialized BIS Analytical Domain schemas. It is not meant to replace cases better covered by a bis:PhysicalType, but rather augmenting it with data needed for a specialized analysis. E.g. an analytical pump should refer to a physical pump type, augmenting it with data needed for a specialized analysis. In the case of a Hydraulic Analysis, for instance, such data could entail classes covering Operating Pump Curves.

A catalog of Storm Events to be used in a Hydrological analysis is an example where introducing a subclass of anlyt:AnalyticalType is more appropriate.

Relationship Classes

AnalyticalElementIsOfType RelationshipClass

A type-instance relation; one that indicates that the specific anlyt:AnalyticalElement is an instance of the defined anlyt:AnalyticalType.

Base Class: BisCore:GeometricElement3dHasTypeDefinition

Strength: Referencing

Strength Direction: Forward

It is meant to be used to relate anlyt:AnalyticalType instances that are not better represented by a bis:PhysicalType instance. E.g. an analytical Storm instance used in a Hydrological Analysis is of type N-years Storm Event.
