行业基础类（IFC）数据模式是通用的，旨在支持建筑行业所需的全方位模型交换。对于建筑施工的某些子域的任何特定工作交换，需要一组模型视图定义（MVD）来精确地指定应该交换什么信息，以及IFC实体将以什么形式和结构使用。定义模型视图定义需要原则性的决定和变通方法，因为IFC本身并没有全面地解决大量的语义问题。确定和讨论的一些问题包括IFC模式中支持的对象、实例、几何、关系和规则的类型，以及在应用程序之间准确交换此类信息的复杂性。本文提出了MVD概念的思想，作为一种面向对象和模块化的机制，嵌入语义的模型视图。我们的结论是，虽然IFC产品模型模式是丰富的表达，它缺乏正式的定义，其实体，属性和关系。为了实现标准化和可重用的模型视图，进一步研究对一个模块化和逻辑框架的基础上正式规范的IFC概念建议。这项研究预计将影响建筑信息建模领域的应用程序的整体互操作性。
The industry foundation classes (IFC) data schema is generic, designed to support the full range of model exchanges needed in the construction industry. For any particular working exchange for some sub-domain of building construction, a set of model view definitions (MVD) is required to specify exactly what information should be exchanged, and in what form and structure the IFC entities are to be used. Defining model view definitions requires principle decisions and workarounds because the IFC itself does not address a number of semantic issues comprehensively. Some of the issues identified and discussed include the typing of objects, instances, geometry, relationships, and rules, which are supported in the IFC schema, and the complexities of exchanging such information accurately between applications. This paper advances the idea of MVD Concepts as an object-oriented and modular mechanism for embedding semantic meaning in model views. We conclude that although the IFC product model schema is richly expressive, it lacks formal definition of its entities, attributes, and relationships. To achieve standardized and re-usable model views, further research towards a modular and logical framework based on formal specification of IFC concepts is recommended. This research is expected to impact the overall interoperability of applications in the building information modeling realm.
