Final Thesis: Token-based Authentication and Authorization in Microservices
Abstract: Microservices represent an architectural approach that is gaining more and more importance to realize highly scalable, reliable and maintainable systems within an agile development process. The advantages of microservice architecture are accompanied by the challenge of designing a distributed system. In such a distributed system, authorization and authentication pose a particular problem. This is…

Research Paper: A Systematic Analysis of Problems in Open Collaborative Data Engineering
Abstract: Collaborative workflows are common in open-source software development. They reduce individual costs and improve the quality of work results. Open data shares many characteristics with open-source software as it can be used, modified, and redistributed by anyone, for free. However, in contrast to open-source software engineering, collaborative data engineering on open data lacks a…

Final Thesis: Processing Open Transport Data: Design and Implementation of an Extension for a Data Pipeline Modeling Language
Abstract: Open transport data enables innovation by offering a vast amount of information for developers, researchers, urban planners, and entrepreneurs to create new applications, services, and business models. However, the lack of specific guidelines for making data “open” has led to the existence of diverse proprietary and heterogeneous open data platforms. Open transport data formats,…

Final Thesis: Design und Implementierung eines Konzepts zur Live-Konfiguration
Abstract: Nowadays a variety of systems generate and handle more and more data. This data is often presented in different formats and has to be retrieved from various locations. The Open Data Service (ODS) presents a system to conquer those tasks. The ODS allows the definition of data manipulation pipelines to process and convert data. Those…

Final Thesis: Development of a Microservice for Open Weather Data
Abstract: Since mid 2017 the Deutscher Wetterdienst (DWD) has been obligated to provide its weather data to the public for free. However, anyone who wants to access it needs to click through a file system hoping to still be on the right path to the desired weather data. Due to confusing folder names this turns into…

Final Thesis: Migration the JValue ODS to Microservices
Abstract: “A world in which consuming open data is easy and safe.“ This is the vision of the JValue Open Data Service (ODS) that aims to bundle finding the right open data, using and combining it into an easy and intuitive process. The daily life of developers should be free from hardships, like writing data crawlers…

Final Thesis: Implementation of a Web-UI for a Guided Configuration Workflow
Abstract: Open Data has a huge potential, but due to its often poor quality and inconsistency most of this data can’t be used, at least not without a lot of effort. Here the Open Data Service is bringing remedy, because this tool can homogenize such data structures. Still, because the data has such great variety, the complexity…

Final Thesis: Design and Implementation of a RESTful API for Heterogeneous Data (in German)
Abstract: Public institutions produce large amounts of publicly available data. Still, due to its poor quality and inconsistent structure, the potential of this data remains unused for the most part. The JValue Open Data Service was established to enhance the quality of this data and give it a standardized structure. It is supposed to make the…
