随着能够确定其位置并进行无线通信的小型便携式设备的出现，移动的和空间感知应用变得可行。这些应用程序依赖于绑定到位置的信息。在本文中，我们提出了NEXUS，这样的应用程序，这是开放的新的应用程序和新的信息提供商，类似于万维网的平台。分布式服务器提供基于位置的信息，这些信息被联合到应用程序的集成视图中。为了实现这一目标，我们提出了增强世界模型的概念，这是一个常见的基于位置的信息的数据模型。我们给出一个例子来展示应用程序如何使用这个平台。
With the emerging availability of small and portable devices that are able to determine their position and to communicate wirelessly, mobile and spatially aware applications become feasible. These applications rely on information that is bound to locations. In this paper we present NEXUS, a platform for such applications, which is open for both new applications and new information providers, similar to the World Wide Web. Distributed servers provide location-based information, which is federated to an integrated view for the applications. To achieve this goal, we present the concept of the Augmented World Model, which is a common data model for location-based information. We give an example to show how applications can use this platform.
