Talk:Wikibase

What about adding a link to wikibase world somewhere on the page?

Pinging @Dan Shick (WMDE): since you worked last on the page.

Good suggestion! I'm adding this to my list of tasks for the next go-round with the docs (should be done by end of Aug.)

Thanks a bunch!

If I type in extension:wikibase I am linked here and yet the first link is Wikibase cloud. Does it mean, that standalone Wikibase instalation is not prefered any more?

Ya that's kind of weird. At least the Docker setup should be linked.

Can we please get a page with a changelog/release ntoes that lists all changes in each Wikibase version similar to how it exists for Mediawiki (https://www.mediawiki.org/wiki/Release_notes)?

These are provided in git by the development team: RELEASE-NOTES-1.37, RELEASE-NOTES-1.38, RELEASE-NOTES-1.39 etc. Is that sufficient for your needs? I don't think copying them onto the wiki would be a good idea, as they would diverge from reality pretty easily (as do the MediaWiki notes).

Hello, I have a weird issue on my wikibase repository where some old items are suddenly wikitext, so trying to edit them gives me errors like '"wikitext" content is not allowed on page Q18155 in slot "Main"'.

I'm too scared to alter the database by hand so I just wanted to delete these faulty items. However, the associated link to the item doesn't go away in the language versions, so I can't link to those articles in a new item, resulting in errors like "The link... is already used by Item Q18155.", even though that item has been already deleted.

Is there by any chance a script available that deattaches the link from an article to a deleted wikibase item? Thanks, cheers and all the best!

Redirecting the old item to the new item via Special:RedirectEntity and then deleting the old item seems to solve this issue. Cheers and all the best!

Hello, I'm running MediaWiki 1.40.0 and I would like to use the main namespace for items like on Wikidata. Can I just add something to LocalSettings.php of the repository or do I have to edit Wikibase.example.php? I'm currently using the default Wikibase.example.php and my LocalSettings.php looks like this.

Also, I'm still having issues with pre-1.37.0 items. They look like this (NSFW) while new items look like this (NSFW).

Any ideas on how to fix this are very much appreciated! Thanks, cheers and all the best!

I'm not sure if this is the best way to do it but this seems to work for me:

LocalSettings.php of the repo:

wfLoadExtension( 'WikibaseRepository', "$IP/extensions/Wikibase/extension-repo.json" );

$wgWBRepoSettings['siteLinkGroups'] = [ 'mywiki', 'pool', 'quote' ];

$wgWBRepoSettings['localClientDatabases'] = array(

    'de' => 'dewiki',

    'en' => 'enwiki',

    'ja' => 'jawiki',

);

$wgExtraNamespaces[120] = "Property";

$wgExtraNamespaces[121] = "Property_talk";

$entitySources = [

    'data' => [

        'entityNamespaces' => [ 'item' => 0, 'property' => 120 ],

        'repoDatabase' => 'datawiki',

        'baseUri' => 'https://data.mywiki.com/wiki/',

        'interwikiPrefix' => '',

        'rdfNodeNamespacePrefix' => '',

        'rdfPredicateNamespacePrefix' => 'wd',

        'type' => 'db'

    ],

];

$wgWBRepoSettings['entitySources'] = $entitySources;

$wgWBRepoSettings['localEntitySourceName'] = 'data';

LocalSettings.php of the clients:

wfLoadExtension( 'WikibaseClient', "$IP/extensions/Wikibase/extension-client.json" );

$wgWBClientSettings['repoUrl'] = 'https://data.mywiki.com';

$wgWBClientSettings['repoScriptPath'] = '';

$wgWBClientSettings['repoArticlePath'] = '/wiki/$1';

$entitySources = [

'datawiki' => [

'repoDatabase' => 'datawiki',

        'baseUri' => 'https://data.mywiki.com/wiki/',

        'entityNamespaces' => [

            'item' => 0,

            'property' => 120,

       ],

        'interwikiPrefix' => '',

        'rdfNodeNamespacePrefix' => '',

        'rdfPredicateNamespacePrefix' => 'wd',

    ],

];

$wgWBClientSettings['entitySources'] = $entitySources;

$wgWBClientSettings['itemAndPropertySourceName'] = 'datawiki';

$wgWBClientSettings['siteLinkGroups'] = [ 'mywiki' ];

$wgWBClientSettings['siteGlobalID'] = 'enwiki';

$wgWBClientSettings['otherProjectsLinks'] = [ 'poolwiki', 'quotewiki' ];

After the changes, I also ran cleanupTitles.php on the repo. Thanks and cheers!

Waht's the relationship between Wikibase and MediaWiki? Is Wikibase a MediaWiki extension? The GitHub readme.md says that Wikibase is multiple MediaWiki extensions and also "other components". Which extensions and components? Thanks.

The mention of "other components" refers to a full-featured Wikibase install, as illustrated in the diagram on the top of this page: Wikibase/Maintaining

There are instructions for installing just the Wikibase extension(s), which these days is a fairly uncommon use case: Wikibase/Installation

You will probably have the best experience using our Docker images, until our Suite team finishes their work on the mechanics of the manual install, and we can update the now quite out-of-date docs: Wikibase/Suite

OK, I researched a bit more and found Extension:WikibaseRepository and Extension:WikibaseClient. If I wanted to set up a very basic Wikibase, would all I need to do is install MediaWiki core and Extension:WikibaseRepository?

Can we add the link to Wikibase/Installation somewhere here? It feels like it should be visible from here.

I have linked Wikibase/Installation at Wikibase/Quick start which is linked on this page.

After attempting to update to MediaWiki 1.38, I also updated the Wikibase extension. Nevertheless, both the new and the old Wikibase are currently producing the same error, hinting at a problem with how Wikibase interacts with the new MediaWiki version 1.38.

From outside Wikimedia there are options however they require effort. Embedding queries from the Wikidata Query Service is the only more or less easy way. No Lua though. Using Lua appears not to be feasilbe (hopefully only at the moment).

I have a third party wiki and I would like to use lua modules like they are used on Wikipedias to fetch data. Is this a matter of configuration or do I need to install Wikibase Client or some other software? Perhaps it is just a MediaWiki configuration parameter. This page leaves a bit me clueless. Thanks for your insight.
