中文 Chinese label / description and English description errors

Hi, I am not confirmed so I can't correct this myself.

The Chinese label and description here are actually Traditional Chinese and the missing Traditional Chinese description should be the Chinese one ("家譜網站維基樹中某人的標識符").

The equivalent simplified Chinese label is "维基树个人标识符" and the equivalent simplified Chinese description is "家谱网站维基树中某人的标识符".

Also, the English description has an error: "identifier for an person in the WikiTree genealogy website", it should read "a person".

Please make these corrections. Thank you. Q699605102 (talk) 13:14, 11 November 2021 (UTC)

@Q699605102: English version has been corrected, and Simplified Chinese label is added. As there is NO policy restricting which variant should appear in "Chinese" label, it is acceptable to place zh-hant in zh. Stang 17:00, 3 January 2022 (UTC)

Other WikiTree pages

There are other pages on WikiTree that it might be good to be able to link to items on Wikidata, such as categories and Free-Space Profiles, e.g.:

• https://www.wikitree.com/wiki/Space:Bridgetown,_WA_-_History_Tree
• https://www.wikitree.com/wiki/Category:Western_Australia

Should this property be adapted to support these, akin to Wikispore ID (P7721), or should new properties be proposed? Or is it a silly idea to link these? Sam Wilson 03:18, 27 February 2024 (UTC)

(I've asked about this on G2G as well.) Sam Wilson 03:32, 27 February 2024 (UTC)

Sorry, I totally overlooked the existence of WikiTree category or space (P7607)! Sam Wilson 04:55, 27 February 2024 (UTC)
