suggestion of splitting this property

Why don't we split this property into for heritage assets and for institutions? If we do it, we need only numerical part of the URL as a identifier. Jawiki has two templates: w:ja:Template:文化遺産オンライン for heritage assets, and w:ja:Template:文化遺産オンライン美術館・博物館 for institutions.

文化財用のプロパティと美術館・博物館用のプロパティに分けてはいかがでしょうか。そうすれば識別子は数値の部分だけでよくなります。日本語版ウィキペディアにも文化財用のw:ja:Template:文化遺産オンラインと美術館・博物館用のw:ja:Template:文化遺産オンライン美術館・博物館の2つのテンプレートが存在します。 本日晴天 (talk) 12:35, 15 November 2023 (UTC)

@本日晴天 The proposal (Wikidata:Property proposal/Cultural Heritage Online ID) states that there are only 77 IDs for institutions (museums). If that is correct, it's not worth an independent property. However, I agree with you that short IDs without the first part would be more practical. Vojtěch Dostál (talk) 12:45, 15 November 2023 (UTC)

@Vojtěch Dostál: Visit https://bunka.nii.ac.jp/museums and change language setting to '日本語' (Japanese), you can see there are 1,047 museum pages on search result. On English version, only 77 pages appear there. 本日晴天 (talk) 13:19, 15 November 2023 (UTC)

@Maculosae tegmine lyncis, Jonathan Groß: ^^ Vojtěch Dostál (talk) 13:25, 15 November 2023 (UTC)

I suppose we could split🪓 this property. I'm not a big fan🪭 of fragmentation, but oh well... Jonathan Groß (talk) 13:32, 15 November 2023 (UTC)

Sorry, yes, I should have checked how many institutions they were with Japanese selected (I was a little surprised..). If the preference is to split, I have no objections. In terms of the technicalities, do I need to propose a further property, or is this discussion sufficient? Thank you, Maculosae tegmine lyncis (talk) 13:45, 15 November 2023 (UTC)

@Jonathan Groß @Maculosae tegmine lyncis @本日晴天 I repurposed this to heritage objects, the one for museums is at Cultural Heritage Online (Japan) institution ID (P12145). I hope nobody minds we skipped the formal proposal process for the other one - anyway, noone else participated in the original proposal. Please check both properties. Vojtěch Dostál (talk) 14:17, 15 November 2023 (UTC)

Thanks. I'll do some work on them later. 本日晴天 (talk) 03:42, 16 November 2023 (UTC)
