Discussion

Automated triples ?

Similar to Wikidata:Project_chat/Archive/2020/02#UUID_search for URN formatter (P7470), one could define additional triples with ARK based on the formatter directly from the various properties using it. --- Jura 09:43, 18 April 2020 (UTC)

Changes to the ARK specification

This post from the folks running the ARK Alliance is relevant: https://arks.org/news/2022-03-18-upcoming-changes-to-the-ark-specification/

implementers will soon be encouraged to publish new ARKs with just “ark:” instead of “ark:/”

How might we modify this property and other related ones to reflect this 2022 guidance? - Fuzheado (talk) 14:23, 4 June 2024 (UTC)

@Fuzheado I think we should update the regex to support it. JhowieNitnek (talk) 06:25, 21 August 2026 (UTC)
