Drawing Analyis Ontology (DAnO)

A composite element that aggregates multiple description elements.

• Dimension ^c
• Dimension Chain ^c
• Text Field ^c

An abstract element in a drawing describing properties of display elements. For instance, a dimension line describing a wall or a text element specifying a schematic pump symbol.

• Composite ^c
• Line ^c
• Symbol ^c
• Text Element ^c

A composite element, comprising exactly 1 DimensionLine, 2 Terminators (at the line's ends), and 1 TextElement (for the dimension value).

• contains ^op exactly 1
  
• contains ^op exactly 2
  
• contains ^op exactly 1
  

A sequence of dimensions connected together to represent cumulative measurements.

The line type for indicating dimensions in a drawing, typically used to represent measurements.

An element representing a real-world component.

• depicts ^op
• is described by ^op

• describes ^op
• isDepictedBy ^op

A visual element in a drawing. Metadata for these elements are stored as DrawingElementMeta instances.

• contains ^op
• has confidence ^dp
• has geometry ^op
• has IFC representation ^dp
• has meta ^op
• is contained in ^op

• contains ^op
• is contained in ^op

• Description Element ^c
• Display Element ^c

Metadata for drawing elements, including inference confidence and methods used.

• inferred at ^dp
• inferred by ^dp
• inferred from ^dp
• inferred with ^dp

A linear description element in a drawing.

• Axis Line ^c
• Dimension Line ^c

A symbol defining the section plane that opens up a view section. Must have a partner symbol and is referred to by a TextElement which is its reference letter.

A symbolic description element representing various annotations or markers.

• Equipment symbol ^c
• Section Symbol ^c
• Terminator ^c

A marker used to indicate endpoints or reference points on a dimension line.

• is referred to by ^op
• refers to ^op

• ends with ^op
• is referred to by ^op
• refers to ^op

A text-based description element in a drawing.

A composite element containing multiple text elements, typically for multiline text.

• GeoSPARQL Ontology

  The default geometry to be used in spatial calculations.
  It is Usually the most detailed geometry.

• GeoSPARQL Ontology
• http://www.opengis.net/spec/geosparql/1.0

  A spatial representation for a given feature.

Indicates that the subject drawing element contains the object drawing element. For instance, lines can contain two endpoints.

Indicates that the subject display element graphically represents a real-world object, such as a building element, zone, or machine part.

Establishes the relationship between a description element and a display element, where the description element describes the display element.

Indicates that a dimension line ends with a dimension line marker.

Links the drawing element to its geometrical representation.

Links meta information to a drawing element.

Indicates that the subject drawing element is part of another drawing element.

Indicates that the real-world subject is depicted by the object display element, which is typically a geometric representation.

Indicates that the display element is described by a description element.

Indicates that the subject dimension line marker is referred to by another dimension line marker.

Indicates that the subject dimension line marker refers to another dimension line marker.

Specifies the confidence level of the inference that identified the drawing element.

Specifies the IFC representation of the drawing element.

Specifies the date when the drawing element was inferred.

Indicates the actor, company, or software that inferred the drawing element.

Specifies the origin file from which the drawing element was extracted.

Indicates the algorithm used to infer the drawing element.

Indicates that the description element is a text element containing the specified string.
