Abstract:

This presentation introduces OpenCode.HR, the national open-source platform established for the academic and scientific community in Croatia. Hosted on the secure infrastructure of the University Computing Centre (Srce) in partnership with FER, FOI, and FERIT, OpenCode.HR provides a sovereign, collaborative environment for developing, sharing, and archiving research software.
Beyond standard Git repository hosting, OpenCode.HR integrates a complete suite of developer tools: GitLab for version control, issue tracking, and CI/CD automation; a central Wiki and community Forum; visual diagramming and collaborative note-taking tools (Excalidraw, HedgeDoc, IT Tools); and a national public Project Catalog with open licensing guidance (OSI, EUPL).
The presentation will explore the platform's architecture and capabilities, followed by a practical onboarding guide for researchers at the IRB. Attendees will learn how to authenticate via AAI@EduHr, establish projects, manage permissions, and adopt best practices for sharing reproducible and open research code.
