“…Information components can be composed from other components as shown in Fig 1. Our prototype was developed using an object database based on the OM model [7] and therefore the metadata of a component is defined in terms of the model primitives which are classes, collections and associations. We show this in Fig 1 as a particular set of model parts to indicate that our notion of information components could be applied to other models.…”

Abstract. We introduce the concept of information components and show how it can allow non-expert users to construct personal information spaces by selecting, customising and composing components defined by the system or other users. The system presented is based on a plug-andplay concept and new user-defined applications can be integrated into the portal-style interface based on default templates which can easily be customised by the users.

“…The actual implementation of the server components was based on OMS, an OODBMS which implements the OM model [16]. Whereas the details of the OM model and OMS system are not important here, we believe that the use of a semantically expressive object data model as the foundation for the infrastructure is important, especially with respect to the integration of the various components and services.…”

Abstract. We introduce the concept of reactive information environments and a general infrastructure for experimentation with such systems. Its asynchronous state-based processing model is described along with the architectural requirements and main components of our infrastructure. These include a general context engine coupled together with a web publishing platform. An application for a public news service is used to motivate the requirements, explain the processing model and show how an application is implemented using the platform.

“…As a content management system, we have chosen our own eXtensible Content Management (XCM) [22,18]. The current version of XCM is implemented in Java and based on OMS Java [26], an object-oriented database management system based on the Object Model (OM) [27], a model that integrates object-oriented and entityrelationship concepts. The original version of XCM supports only a rather simple implementation for context.…”

Abstract. We examine general and abstract approaches to web engineering and context-awareness and how they interact with each other. This involves considering the appropriateness of approaches to context when used by a complex application such as a content management system, while, at the same time, presenting how a content management system can use context information to enrich its functionality. We show that the integration of such systems is feasible only if, in both fields, we make use of approaches based on strong information models. Last but not least, we show that the relationship between context engines and content management systems is not at all a one-sided client-server scenario, but rather a mutually important symbiosis.
