Discussion[edit]

Context at time of creation[edit]

This property is an intermediate step until we have full Commons support. When we get that we can just convert the data. Up until now Commons category links got updated the interwiki way: Decentral with a lot of efforts, see this page for some statistics. By putting this in a central place we are much more efficient and it doesn't really matter anymore what kind of templates some language Wikipedia use to represent the data.

English property title[edit]

Hi. I changed "Commons category" to "Wikimedia Commons category", as I think the former is ambiguous and confusing. My edit was undone in this edit as being "too long". I don't understand. Are there length restrictions or guidelines somewhere? --MZMcBride (talk) 16:34, 6 April 2013 (UTC)Reply[reply]

Dear MZMcBride, names here can be ambiguous, that's why we have a description for this property. This is the standard name used in most Wikipedia's and changing it is confusing. Multichill (talk) 18:30, 9 April 2013 (UTC)Reply[reply]
"Wikimedia Commons" seems to be far more popular as an article title than "Commons", looking at Q565. "Commons" is a regular noun in English. That's where the name "Wikimedia Commons" got its name, of course. It seems kind of silly to now associate "Commons" primarily with a file repository. --MZMcBride (talk) 06:43, 12 April 2013 (UTC)Reply[reply]
Capitalized word Commons is not a regular noun in English, the capitalization is adequate distinguishing. --ŠJů (talk) 15:57, 6 August 2013 (UTC)Reply[reply]

Galleries on Commons[edit]

There're a lot of pages in the main namespace on Wikimedia Commons, they are usually galleries and also often contain interwiki. Is there a property for this? If no, I want to create one. Ain92 (talk) 11:27, 12 June 2013 (UTC)Reply[reply]

No, that one hasn't been created yet. Probably has to do with the fact that galleries are much less used than categories on Commons. Commons has 109.210 galleries and 2.727.327 categories. Multichill (talk) 21:45, 13 June 2013 (UTC)Reply[reply]
Proposed at Wikidata:Property proposal/Sister projects#Commons gallery 7 July 2013. --ŠJů (talk) 15:52, 6 August 2013 (UTC)Reply[reply]

Unique value violations[edit]

This should ignore duplicates which are in different namespaces (article/category/portal). JAn Dudík (talk) 09:28, 1 August 2013 (UTC)Reply[reply]

  • Already done, special form {{Constraint:Unique value|separate category processing=yes}} is used. — Ivan A. Krestinin (talk) 20:06, 6 August 2013 (UTC)Reply[reply]

commons:Template:Disambig[edit]

A check of disambiguation pages would be fine, because a commons category link should not be disambig.

It is possible to check this in the database by joining the table page_props on pp_page = page_id and look for rows, where pp_propname = 'disambiguation'. Thanks. 84.182.127.111 13:48, 6 August 2013 (UTC)Reply[reply]

This check can be included in the "Existing category" check. Treat a disambig category as missing and add a hint behind it to see it in the database report. That would be enough, no need for a new check. 84.182.125.23 02:25, 13 August 2013 (UTC)Reply[reply]

commons:Category:Category redirects[edit]

A check if the linked commonscat is a "category redirect" would be fine. 84.182.125.23 18:35, 12 August 2013 (UTC)Reply[reply]

This check can be included in the "Existing category" check. Treat a category redirect as missing and add a hint behind it to see it in the database report. That would be enough, no need for a new check. 84.182.125.23 02:25, 13 August 2013 (UTC)Reply[reply]
This check is included in the "Existing category" already. — Ivan A. Krestinin (talk) 03:22, 13 August 2013 (UTC)Reply[reply]

Next step[edit]

At Wikidata:Property proposal/Generic#Topic main category I proposed a new property that will replace this one over time. Multichill (talk) 19:01, 9 September 2013 (UTC)Reply[reply]

Now that Commons is linked to Wikidata, is it time to get rid of Commons category (P373) entirely? — JFG talk 02:30, 31 October 2013 (UTC)Reply[reply]
See Wikidata:Requests for comment/Commons links. — Ivan A. Krestinin (talk) 04:10, 31 October 2013 (UTC)Reply[reply]
No, too early. This is used a lot and no replacement is available yet. Multichill (talk) 20:40, 31 October 2013 (UTC)Reply[reply]
Just a late comments, interwiki links are for galleries therefore this property is still essential. John F. Lewis (talk) 20:26, 30 January 2014 (UTC)
