Konferenz 2026: openCost: Navigating Cost Transparency

Von 17. bis 19.3.2026 fand die Auftaktkonferenz für die zweite openCost Projektphase „openCost: Navigating Cost Transparency“ am DESY in Hamburg statt. Die openCost Konferenz 2026 brachte rund 70 Expertinnen und Experten aus dem Bereich Publikationskosten und Kostenerfassung aus zehn Ländern zusammen.

Ziel der Konferenz war es, gemeinsam Impulse für die zweite Projektphase zu setzen, praxisnahe Perspektiven aus der Community zu bündeln und Raum für Vernetzung und Austausch zu schaffen. Das Konferenzprogramm vereinte Beiträge aus dem openCost-Projektteam mit Vorträgen internationaler und nationaler Expertinnen und Experten. Zwei praxisorientierte Hands-on Labs boten den Teilnehmenden zudem die Möglichkeit, gemeinsam mit dem openCost Projektteam konkrete Aspekte des openCost-Standards weiterzuentwickeln. Weiteres zentrales Element der Konferenz war eine interaktive Postersession, in der zahlreiche Projekte, Initiativen und institutionelle Anwendungsfälle vorgestellt wurden.

Alle Vortragsfolien und Posterbeiträge wurden in PUBDB veröffentlicht.
