要实现空间数据基础设施 (SDI) 的优势，需要使用包含要素类型目录 (FTC) 的语义丰富的注册表来表示地理要素类型的语义，包括操作、属性和要素类型之间的关系。具体来说，此类信息提供了 SDI 中使用的概念语义的更完整表示，并支持对已发现资源的高级导航、发现和利用。所提出的方法创建了 FTC 实现，其中给定特征类型的属性、关联和操作被封装在 FTC 内，并且这些概念表示与可以实现 FTC 中的操作的 Web 服务的实现方面分离。这与以前的方法不同，以前的方法将 Web 服务本体中的行为的实现和概念方面结合起来，但将行为方面与概念或特征类型的语义的静态方面分开。这些原则通过使用开放标准实施此类注册表得到了证明。 ebXML 注册信息模型 (ebRIM) 用于合并 ISO 19110 中描述的 FTC，方法是扩展网络目录服务 (CSW) 的开放地理空间联盟 ebRIM 配置文件，并添加大量存储的查询以允许询问符合标准的注册机构的 FTC 组件。该注册表填充了来自海洋领域的要素类型，包含符合世界对象和现场视图的对象。实现的注册表展示了功能类型操作、属性和关联的继承的好处、围绕 FTC 进行导航的能力以及将 FTC 的概念与实现方面分开的优点。需要进一步的工作来形式化模型并包括公理，以增强语义表达力和推理能力的发展。
The use of a semantically rich registry containing a Feature Type Catalogue (FTC) to represent the semantics of geographic feature types including operations, attributes and relationships between feature types is required to realise the benefits of Spatial Data Infrastructures (SDIs). Specifically, such information provides a more complete representation of the semantics of the concepts used in the SDI, and enables advanced navigation, discovery and utilisation of discovered resources. The presented approach creates an FTC implementation in which attributes, associations and operations for a given feature type are encapsulated within the FTC, and these conceptual representations are separated from the implementation aspects of the web services that may realise the operations in the FTC. This differs from previous approaches that combine the implementation and conceptual aspects of behaviour in a web service ontology, but separate the behavioural aspects from the static aspects of the semantics of the concept or feature type. These principles are demonstrated by the implementation of such a registry using open standards. The ebXML Registry Information Model (ebRIM) was used to incorporate the FTC described in ISO 19110 by extending the Open Geospatial Consortium ebRIM Profile for the Web Catalogue Service (CSW) and adding a number of stored queries to allow the FTC component of the standards‐compliant registry to be interrogated. The registry was populated with feature types from the marine domain, incorporating objects that conform to both the object and field views of the world. The implemented registry demonstrates the benefits of inheritance of feature type operations, attributes and associations, the ability to navigate around the FTC and the advantages of separating the conceptual from the implementation aspects of the FTC. Further work is required to formalise the model and include axioms to allow enhanced semantic expressiveness and the development of reasoning capabilities.
