Open, unless

Prefer open-source reuse and collaboration unless legal or security constraints require otherwise.

C2 Platform starts from openness. Reuse of code, patterns, documentation, and working examples should be the default across Dutch government organizations. A closed alternative must be motivated by security, privacy, legal, or contractual constraints.

This principle matters because it lowers delivery costs, reduces vendor lock-in, and makes collaboration between government organizations and ICT suppliers easier. It also supports the reuse of reference implementation examples, Ansible content, and shared documentation.
