The material properties ontology provides the vocabulary to describe the composition of building elements.
Material properties ontology
Relation between a construction component (Layer, profile, constituent) and the materials that define them.
has material
A relation between a constituent set and the specific material constituents.
has material constituent
Relation between an element and its construction based in material constituents.
has material constituent set
A relation between a layer set and the specific material layers.
has material layer
Relation between an element and its construction based in material layers.
has material layer set
A relation between a profile set and the specific material profiles.
has material profile
Relation between an element and its construction based in material profiles.
has material profile set
A relationship between a feature of interest and a property of that feature.
has property
Relationship to connect a material or building element to an specific set of properties.
has property set
Relation between a measurement with a specific material.
is measurement of material
A relationship identifying the unit of measure used for a certain entity.
is measured in
A relationship between a property and the measurements it relates to.
relates to measurement
A relationship between a measurement and the property it relates to.
relates to property
Description of the entity.
description
A relationship to indicate the identifier used in the source database
identifier in database
Ifc identifier of the element in an IFC file.
ifc identifier
Name of the entity.
name
Position of the layer.
position
Thickness of the layer.
thickness
Type of material layer.
type
A relationship defining the value of a certain property, e.g., energy or power. Note that, even if numeric values are expected to enable reasoning, measurement values could use other datatypes.
has value
An element is a generalization of all components that make up an AEC product.
Element
A homogeneous or inhomogeneous substance that can be used to form elements (physical products or their components). (Definition taken from IFC)
Material
A single and identifiable part of an element which is constructed of a number of part (one or more) each having an individual material.
Material constituent
A collection of individual material constituents, each assigning a material to a part of an element.
Material constituent set
A single and identifiable part of an element which is constructed of a number of layers (one or more).
Material layer
A designation by which materials of an element constructed of a number of material layers is known and through which the relative positioning of individual layers can be expressed.
Material layer set
A single and identifiable cross section of an element which is constructed of a number of profiles (one or more).
Material profile
A designation by which individual material(s) of a prismatic element (for example, beam or column) constructed of a single or multiple material profiles is known.
Material profile set
Measurements related to materials.
Measurement
Properties of materials.
Property
N-ary class to unite specific properties related to building elements or materials.
Property set
The unit of measure is a standard for measurement of a quantity, such as a Property. For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called watt. Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of SAREF, but this list can be extended, also using some other ontologies rather than the Ontology of units of Measure (OM).
