Summary
👤
Senior🎓
Top SchoolHans-juergen Rennau is a Senior Software Developer with over a decade of experience specializing in XML and Semantic technologies, currently driving technical work at parsQube in Bonn. He focuses on reconciling tree- and graph-based data models—XML and RDF—through practical tools and XQuery/XSLT-driven generation of code, docs, and testware. Author of several open-source projects including TopicTools, FOXpath, shax and RDFe, he turns theoretical notions of an "XML infospace" into usable developer tooling for navigating and transforming resource trees. His background spans long-term enterprise roles in Java/XML systems and a PhD-level scientific mindset from RWTH Aachen, which surfaces in his methodical, model-driven approach to data interoperability. Notably, he invents expressive DSLs (e.g., FOXpath, shax) that expose less obvious bridges between filesystem/resource navigation and semantic graph validation.
