Evaluating the FIWARE Platform

This paper describes the result of a thorough analysis and evaluation of the so-called FIWARE platform from a smart application development point of view. FIWARE is the result of a series of well-funded EU projects that is currently intensively promoted throughout public agencies in Europe and world-wide. The goal was to figure out how services provided by FIWARE facilitate the development of smart applications. It was conducted first by an analysis of the central components that make up the service stack, followed by the implementation of a pilot project that aimed on using as many of these services as possibl

Analysing FIWAREs Platform - Potential Improvements

The digitalization of the world proceeds continuously. As part of this, we are facing a smart digital future where everything is connected and linked while we are transforming big data into knowledge. The FIWARE platform, which is the result of a series of EU funded projects, supports this transformation. Developers, integrators and end users are able to rapidly create new applications, by using components provided by this platform. We have analyzed central building blocks of the FIWARE platform from different aspects and based on experiments and code reviews - identified various areas of improvements. Our analysis also provides some recommendations for the current code base that can help to improve those FIWARE components under investigation

Building a FIWARE Smart City Platform

This paper describes the architecture of a comprehensive IoT solution entirely based on the FIWARE platform. The application is designed to record data from environmental sensors and to eventually visualize them on a Smart City Dashboard. Besides solving certain architectural and technical issues, one particular challenge arose from the fact that some of the sensors were assumed to be mounted on public transportation vehicles like buses and trams. It could be shown that the FIWARE platform provides a range of components that allows for building such an IoT platform in a very efficient way

Ontology Driven E-Government

Abstract: This paper presents an approach to model ontologies for the e-Government domain as a basis for an integrated e-Government environment. Over the last couple of years the application of semantic methodologies and technologies in the e-Government domain has become an important field of research. A significant number of these approaches aim at automatic service discovery and service orchestration (Lu et al. 2004) (Crichton et al. 2007) by adding and utilizing semantic annotations to web services. In contrast to these approaches it was our idea to use semantic methodologies in a more forward-engineering manner – to create a semantic model first and to use this model e.g. for service selection but also as basis for the automatic generation of “intelligent ” web forms. Thus the ontologies can be seen as a model that forms the basis of a Model Driven Architecture (Miller et al. 2001) approach to e-Government. That is why we call it Ontology Driven e-Government. The principle is rather straightforward. Every public service is semantically modeled and contains references to the required input elements. Any constraints on the service input element – also known as preconditions – can be expressed by semantic rules and evaluated by semantic reasoners. This allows for an automatic creation of (web) forms and interactive plausibility checks of data gathered from the user. Instead of scattering logic over numerous functions and procedures in all possible layers of an application, it is now consistently kept in the semantic model. Another key advantage of this approach is that the knowledge of public services becomes available in a machin
