Supplementary Materials of the 1st Interactive Workshop on the Promotion of Open Science in Requirements Engineering 2026 (Re-OpenS'26)

Summary This collection contains all the supplementary materials of the 1st Interactive Workshop on the Promotion of Open Science in Requirements Engineering 2026, co-located with the 32nd International Working Conference on Requirements Engineering: Foundation for Software Quality 2026. The materials complement the workshop sessions and provide participants with resources to enhance their understanding and application of open science principles in the field of Requirements Engineering (RE) by leveraging the Open Research Knowledge Graph (ORKG) and ORKG Ask for FAIR scientific information. These materials contain all presentation slides and exercise materials so that everyone can repeat the theoretical presentations independently and carry out the practical exercises themselves at any time. Contents 1. Slides - All slides used in the tutorial. Files Description 0. RE-OpenS'26 - All Sessions.pdf The complete set of all slides used in the workshop, which are also provided individually for each session of the workshop. 1. RE-OpenS'26 - Welcome.pdf The welcome with an overview of the content of the workshop. 2. RE-OpenS'26 - Introduction to Open Science and REFSQ's Open Science Initiative.pdf The theoretical introduction to open science and REFSQ's Open Science Policy regarding their importance, benefits, and incentives for researchers themselves and the wider RE community. 3. RE-OpenS'26 - Introduction to the ORKG and ORKG Ask.pdf The theoretical introduction to the Open Research Knowledge Graph (ORKG) and ORKG Ask. 4. RE.OpenS'26 - Using SciKGTeX.pdf The practical exercise, with detailed step-by-step instructions on how to use the LaTeX package SciKGTeX to create a FAIR-annotated publication and import it into the ORKG. 5. RE-OpenS'26 - Using the ORKG Ask and ORKG CSV Import.pdf The practical exercise, with detailed step-by-step instructions on how to use ORKG Ask and the ORKG CSV Import to describe publications regarding their scientific information and use these descriptions to create and publish an ORKG comparison. 6. RE-OpenS'26 - World Café, Reflection, and Closing.pdf The closing session focuses on developing a roadmap for future editions of RE‑OpenS and gathering insights on how to further improve REFSQ’s Open Science Initiative through a Word Café and feedback session. 2. Exercise Materials - All exercise materials used in the tutorial. 2.1 SciKGTeX Materials Folder Description SciKGTeX_Example The folder contains an example publication and all required SciKGTeX files for annotating the scientific information.
