随着传感器网络和智能设备数量的迅速增加，产生了越来越多的信息。各种各样的来源以不同的格式生成和发布信息，因此强调互操作性是物联网（IoT）成功的关键先决条件之一。数据中心的BT Hypersonic为共享和消费来自广泛来源的可用数据集提供了一个焦点。在这项工作中，我们提出了一个语义丰富的BT Hyperlink在数据中心，使用公认的语义Web标准和工具。我们提出了一个本体，捕捉导入数据的语义，并通过SPARQL和SQL查询之间的映射呈现BT SPARQL端点。此外，联邦SPARQL查询允许对多个基于中心的数据源和外部数据源进行查询。最后，我们提供了两个用例，以说明我们的语义方法所提供的优势。
An increasing amount of information is generated from the rapidly increasing number of sensor networks and smart devices. A wide variety of sources generate and publish information in different formats, thus highlighting interoperability as one of the key prerequisites for the success of Internet of Things (IoT). TheBT Hypercat Data Hubprovides a focal point for the sharing and consumption of available datasets from a wide range of sources. In this work, we propose a semantic enrichment of theBT Hypercat Data Hub, using well-accepted Semantic Web standards and tools. We propose an ontology that captures the semantics of the imported data and present theBT SPARQL Endpointby means of a mapping between SPARQL and SQL queries. Furthermore, federated SPARQL queries allow queries over multiple hub-based and external data sources. Finally, we provide two use cases in order to illustrate the advantages afforded by our semantic approach.
