Collaboration in the public sector typically happens between similar organizations and through an overarching coordinating body. How a-typical is then the collaboration between the Dutch Tax Office and the semi-public Grid Operator Alliander. Yet the goals for their open source activities are similar and thus the OSPO's are collaborating to establish sound Open Source practices. Meanwhile there is a larger community of public and semi-public OSPO's that are taking on multiple shared goals.

In this presentation Karel Rietveld and Nico Rikken will go over their learnings:

- Unique benefits of an OSPO-collaboration that is national and consists of (semi-)public organizations
- Practical examples of collaboration
- How a small collaboration has grown to a larger collaboration
- The road to the current working structure with working groups
