The GDNG extension to DPV introduces a 'P'-prefixed IRI scheme because German statutes use 'Paragraph,' not 'Artikel,' as their outermost textual unit
The Data Privacy Vocabulary's established convention for citing a legal sub-unit inside an IRI — e.g. A6-1-b for GDPR Article 6(1)(b) — was built around EU regulations, whose outermost textual unit is the "Article." That convention does not transfer cleanly to German law: as Flake, Henke, Kuntz, Löbe, Pandit and Draeger report (arXiv:2610.37527, 2026) in their "lessons learned" section on extending DPV to the German Health Data Use Act (GDNG), German statutes' outermost unit of text is instead the "Paragraph" (§), not "Artikel." The authors state this mismatch "led to confusion while discussing the regulation with the DPVCG in English," and was resolved by introducing a distinct, "P"-prefixed IRI pattern for the GDNG extension — e.g. de-gdng:P6-3-Consent — alongside the existing "A"-prefixed pattern used for EU-regulation extensions.

“In Germany, the outermost unit of text inside a regulation is typically called "Paragraph" rather than "Artikel". Therefore, the IRIs in GDNG extension that refer to a certain paragraph start with a "P" and not with an "A" as in the example de-gdng:P6-3-Consent.”
