Making it avalible for Mediawiki 1.19.0

Hi could you make this extension also avalible for Mediawiki 1.19.0 please 86.171.33.224 18:39, 7 May 2013 (UTC)

This is not possible because it needs the content handler which has only been introduced later. Lydia Pintscher (WMDE) (talk) 09:23, 8 May 2013 (UTC)

Extension:Wikibase Client

Please change the snapshot taken from Extension:Wikibase and move it to Extension:Wikibase Client and keep that snapshot for Extension:Wikibase 86.171.33.224 18:48, 7 May 2013 (UTC)

Wikibase Client installation

I installed wikibase lib and client Configured as follows $wgWBSettings['repoUrl'] = '//www.wikidata.org'; $wgWBSettings['repoScriptPath'] = '/mediawiki'; $wgWBSettings['repoArticlePath'] = '/mediawiki/$1'; $wgWBSettings['siteGlobalID'] = 'mywiki'; $wgWBSettings['repoDatabase'] = 'mwikidb'; $wgWBSettings['changesDatabase'] = 'mywikidb';

I tried to get a property from repoUrl with:

but nothing happen .

Some hints how to configure or use wikidata in mywiki ?

Regards g 77.56.48.49 16:40, 17 August 2013 (UTC)

Do you have Wikibase Repo enabled somewhere? Wikibase Client cannot access wikidata.org, except for within wikimedia servers where the wikidata clients (e.g. wikipedia) are able to access the wikidata database directly. If you have your own Wikibase Repo instance, then update repoUrl and double check the repoDatabase setting (e.g. do you really intend it to be different from changesDatabase?). Cheers. Katie Filbert (WMDE) (talk) 11:06, 19 August 2013 (UTC)

I was thinking it should be possible to have the client only as reader, to access

the wikidata data.

FYI:

I defined my own Wikibase Repo and it was working, but this was not the original goal,

Thanks g 77.56.48.49 20:41, 21 August 2013 (UTC)

A third-party client like you want to do it is not possible yet. Lydia Pintscher (WMDE) (talk) 09:06, 22 August 2013 (UTC)

It should not be far off... Maybe we ought to provide a list of things not working yet. This is all I can think off, and those are just guesses as I'm not up to speed with client state:

• No change propagation system usable by non-WMF available yet, would need custom coding/setup from third party side at present
• Not able to write back to repo due to cross domain request policies messing with API requests (this one I'm really not sure about)

Anything else? Jeroen De Dauw (talk) 20:06, 22 August 2013 (UTC)

Is it possible now? Or not yet? I would like to access to Wikidata data from an external wiki. Is there any workaround? Thanks. Emijrp (talk) 14:34, 8 July 2015 (UTC)

It's not possible yet and to be honest there are a ton of more important things we need to do before we get to this  :/ Lydia Pintscher (WMDE) (talk) 14:54, 9 July 2015 (UTC)

It's been a while. Is this possible yet? Ike Hecht 21:55, 8 February 2019 (UTC)

Is it possible now? Or not yet? Jmkim dot com (talk) 09:45, 13 March 2021 (UTC)

Database tables

It would be useful if the extension(s) page(s) documented the database tables they use: Wikibase/Installation mentions "sites" and "interwikI" incidentally, but that's not useful.

In particular, I'm interested in knowing whether the repository's ID for the client's pages are stored in a database table, and if yes which and in what format. Nemo 11:11, 5 October 2014 (UTC)

Error readapidenied between private clients

I installed a Wikibase repo and 2 clients (all private) but the queries of wikibase between the wikis don't work.

You can see the error when myfrwiki calls a query to myenwiki (event JS in the field page in the popup "Link with page")

/**/jQuery111107420199392363429_1416306133780({

  "error": {
      "code": "readapidenied",
      "info": "You need read permission to use this module",
      "*": "See https://en.xxxxx.fr/w/api.php for API usage"
  }


})

I use the parameters for the family wiki and it works :

• $wgCrossSiteAJAXdomains = array( "en.xxxxx.fr", "fr.xxxxx.fr", "pool.xxxxx.fr" );
• $wgSharedDB = "mydbpool";
• $wgCookieDomain = ".xxxxx.fr";
• $wgSharedTables[] = "ipblocks";
• $wgSharedTables[] = "interwiki";

Can you help me ? Thanks Karima Rafes (talk) 11:50, 18 November 2014 (UTC)

I don't know what the issue is here, though want to caution you against using the Wikibase software at present. IMO it is not ready for third party production usage. Jeroen De Dauw (talk) 06:41, 1 December 2014 (UTC)

Wikibase? Wikibase Client? Wikidata build? huh? what?

As I understand it

• Wikibase = awesome technology
• Wikidata = site running that technology to provide millions of facts about items on Wikimedia projects
• Wikibase Client = lighterweight code for other wikis in the cluster that want to use facts from wikidata.

None of this is apparent wondering around

Meanwhile this page has

{{TNT|Update}} {{TNT|Expand|reason=looks like something added to wrong page}}

but this extension is not obsolete, it's in use on tons of Wikimedia wikis (but not mediawiki.org).

I think

• if you want to develop, check out Extension:Wikibase and follow instructions
• if you want to see how WMF configures the site https://wikidata.wikimedia.org , check out Extension:Wikidata build and wander around in the operations/mediawiki-config repo, primariy in wmf-config/Wikibase.php

I still can't figure out what Wikibase Client is. SPage (WMF) (talk) 21:27, 2 April 2015 (UTC)

I'd guess Wikibase Client is this.

http://comments.gmane.org/gmane.org.wikimedia.wikidata/5353 is related. Ricordisamoa 18:14, 3 April 2015 (UTC)

Wikibase Client was a separate extension, hosted at https://gerrit.wikimedia.org/r/#/admin/projects/mediawiki/extensions/WikibaseClient. But this separate code repository was abandoned and Wikibase Client became a directory in Extension:Wikibase Repository. The separate documentation on this page is not fully up to date since then. The plan is to separate the two extensions again. Thiemo Kreuz (WMDE) 13:13, 29 March 2016 (UTC)

I don't know why it doesn't work

I tried to install the wikibase client.

I obviously failed because on my wiki a message displays "access to the database impossible".

This is what I wrote in the localsettings:

require_once "$IP/extensions/Wikibase/client/WikibaseClient.php";
require_once "$IP/extensions/Wikibase/client/ExampleSettings.php";

$wgWBClientSettings['siteGlobalID'] = 'frwiki';
$wgWBClientSettings['repoDatabase'] = 'brnathan_mw3';
$wgWBClientSettings['changesDatabase'] = 'brnathan_mw3';</pre>
I have the following error in the errorlog:

== Property not found ==

Hi, after upgrading to MediaWiki 1.28.0, I'm getting the following error when I use <code>{{#property:P1|from=Q3}}</code> in an article:

:I'm afraid there is not enough information to fully understand the problem. If it worked before but stopped working after an update it must be something we updated in the code base, but you did not updated in your configuration. Please have a look at the example configuration in <code>Wikibase.example.php</code>. The <code>entityNamespaces</code> setting changed a bit. I also wonder if you checked your Q3 item. Are you sure it contains a statement for the property P1? [[User:Thiemo Kreuz (WMDE)|Thiemo Kreuz (WMDE)]] 13:54, 5 December 2016 (UTC)
:{{FlowMention|Thiemo Mättig (WMDE)}}, thanks for your help!
:In <code>Wikibase.example.php</code>, I set <code>$wgWBRepoSettings['siteLinkGroups'] = [ 'myprojectname' ];</code> and <code>$wgWBRepoSettings['specialSiteLinkGroups'] = [ 'pool', 'data' ];</code> like I used to do.
:I now changed <code>$wgWBRepoSettings['entityNamespaces'][CONTENT_MODEL_WIKIBASE_ITEM] = NS_MAIN;</code> to <code>$wgWBRepoSettings['entityNamespaces']['item'] = NS_MAIN;</code> and <code>$wgWBRepoSettings['entityNamespaces'][CONTENT_MODEL_WIKIBASE_PROPERTY] = WB_NS_PROPERTY;</code> to <code>$wgWBRepoSettings['entityNamespaces']['property'] = WB_NS_PROPERTY;</code> in <code>LocalSettings.php</code>, since it looks to me like this is the current way to do this (by the way, should this be updated [[Extension:Wikibase_Repository#Setting_up_items_in_the_main_namespace|here]] or is it still up-to-date?). 
:I'm still getting the old "Property not found" error though. P1 is actually still in the statements section of Q3. It used to work before, but I checked it anyway like a million times :) Cheers! [[User:Till Kraemer|Till Kraemer]] ([[User talk:Till Kraemer|talk]]) 15:43, 6 December 2016 (UTC)

== Javascript: wikibase is not defined ==

After enabling the Wikibase client, I was hoping to be able to use the <code>wikibase.client</code> javascript resources, but it seems they're not being loaded: <code>wikibase is not defined</code>

== Error installing Extension:Wikibase ==

Hi Everybody,

in advance, thankyou for reading me.

I want to install the extension: wikibase, since I need it in order to use Template:Infobox person .

I copy the extension folder into wiki/extension/ folder, and I copy the following lines to the LocalSettings.php file, as it is recommended in the installation guide.

$wgEnableWikibaseRepo = false;

$wgEnableWikibaseClient = true;

require_once "$IP/extensions/Wikibase/client/WikibaseClient.php";

require_once "$IP/extensions/Wikibase/client/ExampleSettings.php";

And still I am getting the error message: Sorry, we have problems. Cannot acces the database.

What can I do?

Thankyou for your attention,

Jordi [[User:Benet tallaferro|Benet tallaferro]] ([[User talk:Benet tallaferro|talk]]) 23:06, 19 May 2017 (UTC)
:What exactly do you want to achieve? I assume you copied the code of [[:en:Template:Infobox person]] to a local MediaWiki installation you own? Is this correct? Do you want to use data from wikidata.org in this template, or from your own Wikibase Repo? Note that the Wikibase Client software currently needs direct database access to the Repo. Both must run on the same server because of this. [[User:TMg|TMg]] 09:23, 20 May 2017 (UTC)

{{FlowMention|Tobias Gritschacher (WMDE) }}, thank you for improving the documentation and moving advanced details into their own page. However, I think the last changes in this page is hiding important basic information that should appear here. For example: how to use #property is now located in [[Wikibase/Installation/Advanced configuration]]. Also,  the last changes break the " parser functions" link in the intro. Can you please fix it?

{{Archive top|result={{Tracked|T166429}}|status=resolved}}

I put this into the article on zh.wp. And I found that it outputs a incomplete code-block of Language Converter.

like [[:w:zh:新浪微博]] , it outputed that '<code>http://www.weibo.com">http://www.weibo.com;zh-hans:http://www.weibo.com;zh-hant:http://www.weibo.com;zh-cn:http://www.weibo.com;zh-hk:http://www.weibo.com;zh-mo:http://www.weibo.com;zh-sg:http://www.weibo.com;zh-tw:http://www.weibo.com;}-</code>'

But I use Special:ExpandTemplates to parse it, it's output is clean, just 'http://www.weibo.com'.

[[:meta:Tech/News/2016/41]]has a news about 'Language converter syntax will soon no longer work inside external links.' , Is it about this problem? And I can't find the function of {{#property:}} in the source code of Wikibase, so I want to know whether it have a i18n Mediawiki-namespace page to control it ,or a hard code to format the output of URL with Language Converter? [[User:Cwek|Cwek]] ([[User talk:Cwek|talk]]) 02:23, 27 May 2017 (UTC)
:I suggest you to report it on Phabricator, the bug tracker of Wikimedia, as I’m not sure if any developer is watching this page, and there you can tag both Wikidata and Language Converter so that developers of both products will notice it.

Did you made sure to run the update.php maintenance script on both the repo and the client database? Thiemo Kreuz (WMDE) 03:18, 13 August 2018 (UTC)

Hi @Thiemo Kreuz (WMDE), thanks for your reply! Yeah, I ran the update script and I just did it again, just to make sure. Same error :/ With older MediaWiki versions I used the Wikidata extension bundle, but it seems to be discontinued. This time, I installed Wikibase using Composer as suggested.

I just noticed that Wikipedia uses WikimediaBadges and WikibaseLexeme, so I wanted to install them too, just in case. Wasn't able to install WikibaseLexeme on the client wiki though. Showed me a blank page.

The LocalSettings.php on the client wiki looks like this:

I also noticed that on Wikidata the client is also activated. Did that for my repo too, left $wgEnableWikibaseClient = false; untouched though.

I don't really know what to do right now :/ Any help is more than welcome. Thanks and cheers! Till Kraemer (talk) 15:28, 14 August 2018 (UTC)

• Please check if the MediaWiki and Wikibase versions you are using match.
• WikimediaBadges and WikibaseLexeme are optional. If you are not sure, you probably don't need them.
• The client's configuration format changed. Even if there is backwards-compatibility code in place, it might have failed for you for some reason. What you can try is to add the new format $wgWBClientSettings['repositories'] = …; either in addition or replacing the old $wgWBClientSettings['repoDatabase']. See WikibaseClient.example.php for an example. Thiemo Kreuz (WMDE) 08:57, 15 August 2018 (UTC)

Hi @Thiemo Kreuz (WMDE), thanks for your suggestions!

I just checked the versions again. I'm running MediaWiki 1.31.0 on the clients and on the repo and the Wikibase version file looks like this:

Wikibase: REL1_31
2018-04-17T22:37:46
8178d16

I added $wgWBClientSettings['repositories'] = 'datawiki'; to LocalSettings.php, but when I run the update script, the following error appears:

[abc123567] [no req]   TypeError from line 117 of /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php: Argument 1 passed to Wikibase\WikibaseSettings::getEntityNamespacesFromRepositorySettings() must be of the type array, string given, called in /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php on line 111

This also happens when I remove $wgWBClientSettings['repoDatabase'] = 'datawiki';. I'm running PHP 7.0.8. Should I upgrade to 7.0.28?

Thanks and cheers! Till Kraemer (talk) 14:01, 15 August 2018 (UTC)

The repositories setting is an array, as shown in the example. The empty array key '' might look confusing. This identifies the default repository, which is what you need. All you need to do is to fill in the values for repoDatabase and baseUri, I believe. Thiemo Kreuz (WMDE) 15:34, 15 August 2018 (UTC)

Hi @Thiemo Kreuz (WMDE), thanks for your help!

For some reason, just adding repoDatabase and baseUri doesn't work for me. If I add this to LocalSettings.php...

$wgWBClientSettings['repositories'] = [
			'repoDatabase' => 'datawiki',
			'baseUri' => 'https://data.mywiki.com/entity',
	];

...I get the following error:

[abc1234567] [no req]   TypeError from line 120 of /path/to/mywikis/en/w/extensions/Wikibase/lib/includes/WikibaseSettings.php: Argument 2 passed to Wikibase\WikibaseSettings::Wikibase\{closure}() must be of the type array, string given

#11 /path/to/mywikis/en/w/maintenance/update.php(245): require_once(string)

So I added the whole block:

$wgWBClientSettings['repositories'] = [
		'' => [
			'repoDatabase' => 'datawiki',
			'baseUri' => 'https://data.mywiki.com/entity',
			'entityNamespaces' => [
				'item' => WB_REPO_NS_ITEM,
				'property' => WB_REPO_NS_PROPERTY
			],
			'prefixMapping' => [ '' => '' ],
		]
	];

I was now able to run the update script successfully and the item ID links (like https://data.mywiki.com/wiki/Special:EntityPage/Q1234567) show up on the client wiki. However, the interwiki links don't appear on the client wiki and I have the following error in my log file:

Not sure what I'm missing here :/

Thanks and cheers! Till Kraemer (talk) 16:15, 16 August 2018 (UTC)

Oh, I have never seen this message before. It sounds like a secondary database table got out of sync. I'm afraid I need to hand over to the core Wikidata team. Maybe Leszek can help?

PS: I just realized your item namespace is NS_MAIN, not WB_REPO_NS_ITEM. You need to fix this in the configuration you just added. Thiemo Kreuz (WMDE) 16:48, 16 August 2018 (UTC)

Hi @Thiemo Kreuz (WMDE), I changed WB_REPO_NS_ITEM to NS_MAIN in LocalSettings.php as you suggested and woohoo, it works perfectly now! :) Thank you so much for your help! I'm soo happy now! :) Long live Wikibase and Thiemo Kreuz! :)

I wonder I can run mediaWiki 1.32 without database replication?

Alex Lai 2601:144:4100:A372:20A1:4DF9:D7DC:A349 (talk) 22:50, 17 February 2019 (UTC)

Hey Alex. Is this question related to Wikibase? If not, I'm afraid this is the wrong page to ask. I'm also not sure if we are talking about the same when we say "database replication". What is the exact issue you run into? Thiemo Kreuz (WMDE) 06:50, 18 February 2019 (UTC)

Need help with installing to Mediawiki 1.31

Can somebody please post what exactly you put into your LocalSettings.php for a client only install of this extension to access wikidata.org? Thanks. Zzmonty (talk) 13:15, 31 August 2018 (UTC)

What the section Wikibase/Installation#Adjust your LocalSettings.php describes should be all that's needed. Was this not successful? If not, what's missing for you? Thiemo Kreuz (WMDE) 15:30, 31 August 2018 (UTC)

Tried that and nothing works. I also looked at the advanced installation, and tried to copy those items and it did not work. If you got this to work with a 1.31 mediawiki, and the client only part of this extension, if you could just look at your LocalSettings.php file and just copy everything that you have in that file related to this extension it would be much appreciated. Maybe another extension I have installed is conflicting with this extension. i don't know. I just know that i followed the instructions a couple of times, and I could not get this extension to even load.

The only other item is that I don't have composure, so I was trying to manually install the extension. Did I miss some dependency either with a third party application or else another extension? Zzmonty (talk) 20:47, 1 September 2018 (UTC)

Please describe what "did not work" means. What error message do you get on which page in which namespace?

Having the libraries Wikibase depends on installed via Composer is a must. I'm not aware of a way to do this "manually". Thiemo Kreuz (WMDE) 07:40, 2 September 2018 (UTC)

Then that is where the problem is, because I did not use composer. Zzmonty (talk) 17:31, 3 September 2018 (UTC)

Extension not working on tr.wiktionary

On this module, there is a line "local URL = mw.wikibase.getEntityUrl(wikidataItem)", but it won't work the way it should like its english wiktionary version. When I remove "mw.wikibase" from if condition it says "wikibase is a nil value", why is that? ~ Z (m) 14:28, 14 September 2018 (UTC)

All Wiktionaries except English don't yet have arbitrary access enabled. You can file a ticket on phabricator.wikimedia.org to get it enabled. Lydia Pintscher (WMDE) (talk) 20:10, 15 September 2018 (UTC)

Automatic labels

Can someone explain me why the title of a wiki page is not automatically used for the label of the item when a wikipedia page is added in that language from the wikipedia? It is this way by default if you create an item, but not if you only add a link to a wikipedia page. Why is that behaviour of this Wikibase Client?

Thanks in advance. Paucabot (talk) 10:59, 6 December 2018 (UTC)

Usage with WikibaseMediaInfo ("Structured Data")

Hi, I'm trying to get property value from Structured Data for File:Monument Demba et Dupont.jpg. To do this I invoke {{wikidata|P6216|from=M76359368}} (M76359368 is its id according to commons:Commons:Depicts#API_access). However, it doesn't work (error "Identifier not found"). How to properly query this information? 176.36.227.144 (talk) 10:27, 20 October 2020 (UTC)

(note: I invoked that template in the context of Ukrainian Wikipedia) 176.36.227.144 (talk) 10:29, 20 October 2020 (UTC)

Lua access is different from API access. Lua access is currently only possible within Commons. Tacsipacsi (talk) 19:30, 20 October 2020 (UTC)

@Tacsipacsi That's sad, but I suspect there has to be plans to add Lua support (smth like WikibaseMediaInfoClient extension). Maybe you are aware of such phabricator issue or have a roadmap link (I'd subscribe to their updates)?

Also, is there any other way to query some data (not just structured data) about Commons media files from a Wikipedia module? 176.36.227.144 (talk) 20:45, 20 October 2020 (UTC)

I tried to find something about the cross-wiki support (I’m pretty sure I once read that there’s no cross-wiki support yet), but I didn’t succeed.

Some very basic information (dimensions, MIME type etc.) can be queried about any (Commons or local) file using the title library. Tacsipacsi (talk) 00:41, 21 October 2020 (UTC)

How set up Wikibase client to another DB server

Dynamic tables with Wikibase

Hello! On a language wiki, I'm trying to create tables that update automatically when new articles are added to a category. The table should contain article names and associated properties via their Wikibase items.

The Idea behind it is that I  enter the data into Wikibase items, instead of adding it manually into tables. I'm currently trying to set this up using Wikibase, Lua, and DynamicPageList4. I've been working on this for days now with Grok, ChatGPT, and Gemini, and it feels like I'm getting nowhere. The AIs are also suggesting me to use SMW, which I try to avoid if it is not necessary.

Are those dynamic tables something that can be done with my current setup, or do I indeed have to add the extensions Semantic MediaWiki and Semantic Wikibase? Thanks for any info on this, cheers and all the best! Till Kraemer (talk) 15:14, 14 February 2026 (UTC)

As far as I see, the output of Extension:DynamicPageList4 is invisible to parser functions or Lua code, so you won’t be able to list the category contents. This is probably among others for caching reasons, so if you use any other solution, you should make sure that the table actually gets regenerated when a new page is added to the category, rather than the previous state getting stuck. I don’t know how good SMW is at this.

For a similar problem, although not using categories, w:Template:Wikidata list was invented on WMF wikis, which solves the problem by instructing a bot to do periodic updates – if you’re able to run a bot, that would also be a solution. —Tacsipacsi (talk) 21:24, 14 February 2026 (UTC)

@Tacsipacsi, thank you so much for weighing in on this! That helps a lot! I installed the extensions Semantic MediaWiki and Semantic Scribunto, and created a Lua module thanks to the help of Gemini. Now the dynamic tables work perfectly! Thanks again for your help, cheers, and all the best! PS: Thanks to Grok's advice, I did not install the Semantic Wikibase extension. Apparently, it is outdated and not needed for my tables. Till Kraemer (talk) 22:14, 15 February 2026 (UTC)
