Exploring EU Election 2024 Results of Bavaria Open Data With Jayvee
The EU publishes large amounts of open data on its own open data portal, https://data.europa.eu. They re-use their own open data to allow citizens to gain insights into the EU elections in 2024 (see, for example, these visualizations). Based on published open data, citizens can run their own analysis. Sadly, depending on the data set,…

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: Evaluation of Open Data Using the Example of a Public Transport Navigation Website
Abstract: This thesis deals with the implementation of an open source trip planner for the public transport association VGN, the results of which take into account both parking the bicycle at a stop and taking the bicycle on public transport until the destination. In principle, software already exists that enables multimodal navigation with public transport,…

Final Thesis: Requirements for an Open Mobility Data Processing Language
Abstract: Exchanging open data plays an increasingly important role in the domain of mobility. A wide range of participants provide and consume data, involving subjects such as traffic management or public transportation. To make use of the data, programming proficiency is necessary in order to realize data engineering tasks. However, a dedicated Domain-Specific Language may decrease…
