Article 5 sets the conditions for re-use: non-discrimination, transparency, no distortion of competition, anonymisation / pseudonymisation / secure-processing-environment requirements for protected categories (in particular personal data). Article 5(9) requires that any re-use of personal data under the Article 5 conditions retains the GDPR as the governing personal-data regime. Article 6 governs fees: re-use is generally free or limited to cost recovery; transparent and non-discriminatory fee structures.
This control maps to 3 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 3 it maps to, and the evidence behind each claim, over MCP and REST.
