This is a summary of the Developers Workshop (SemDev) co-located with the 21st International Conference on Semantic Systems (SEMANTiCS). In theory, the interplay between academia and industry is bidirectional. Industry informs academics about real-world problems that require novel solutions. Academics can then design novel algorithms as solutions, which they evaluate based on software prototypes. These research outcomes can then be picked up by industry, and become implemented in commercial products and services. In practise, this interplay unfortunately does not flow as smooth as theorized. First, problems in industry do not always become apparent to the research community. This can cause real-world problems to not get picked up by researchers, or researchers coming up with solutions for which no real problem exists. Second, the research outcomes that academics consider finished may still not be practical enough to be useful in industry. Moving from a research prototype towards a technical-ready implementation can still require non-trivial problems to be solved, which can require additional research. As such, there is a need for a common ground where academics and companies can discuss real-world problems, and gaps between research prototypes and technical-ready products. This workshop aims to ifll this need, and is therefore relevant for researchers and industrial partners. In this edition, we received ten submissions, from which four were accepted as software talks, and ifve were accepted as software demos. Each submission underwent a fully open peer-review process with at least three reviews per paper using the OpenReview platform. The website of the workshop is: https://semantics2025.semdev.org/
