Summary:Disclosed is a method for representing a hierarchical schema for a three-dimensional information model for primary structures of road. According to an embodiment of the present invention, provided is a data structure in which a schema for defining a standard information model for a tunnel is represented. The schema a) is defined in an express language; b) follows a hierarchical structure regulated in IFC4 or ISO 16739; c) includes a plurality of shape entities representing the shapes of elements configuring the tunnel and a plurality of type entities representing the type of each shape entity, wherein the each type entity has an enumeration data type for enumerating a plurality of detailed types; and d) allows the shape entities and the type entities to be ranked lower than a plurality of conceptual entities configuring a hierarchical structure. 터널을 포함한 도로 주요 구조물에 대한 3차원 정보모델을 위한 계층적 스키마 표현 방법을 개시한다. 본 실시예의 일 측면에 의하면, 터널에 대한 표준정보모델을 정의하기 위한 스키마(Schema)가 표현된 데이터 구조를 제공한다. 상기 스키마는, (a) Express 언어로 정의되고, (b) IFC4 또는 ISO 16739에 규정된 위계구조를 따르되, (c) 상기 터널을 구성하는 부재(Element)들의 형상을 나타내는 복수의 형상 엔티티(Entity) 및 각 형상 엔티티의 타입(Type)을 나타내는 복수의 타입 엔티티를 더 포함하고, 각 타입 엔티티는 복수의 상세 유형을 열거하는 열거형 데이터 타입(Enumeration data type)을 가지며, (d) 상기 복수의 형상 엔티티 및 상기 복수의 타입 엔티티는, 계층 구조를 이루는 복수의 개념적 엔티티의 하위에 위치한다.
