Extension talk:Wikibase Client/Flow

I have my own installation of wikidata. I want to connect it to my wiki. But in the configs I see only direct access to the database on the server of the main wiki - repoDatabase. How can I specify a different DB server?

$wgWBClientSettings['entitySources'] = [ 'local' => [ 'entityNamespaces' => [ 'item' => 0, 'property' => 120, 'lexeme' => 146, ], 'repoDatabase' => "wikidata", //'repoDatabase' => false, 'baseUri' => 'my-dat/entity/', 'rdfNodeNamespacePrefix' => 'wd', 'rdfPredicateNamespacePrefix' => , 'interwikiPrefix' => 'd', ], ];

Ops Problem solved I debug error and try for resolve this content_models table in database of Wikibase repo site requirement backup

Hi

For Change siteGlobalID from es to eswiki, me empty wbc_entity_usage table

and change $wgWBClientSettings['siteGlobalID'] = 'es'; to $wgWBClientSettings['siteGlobalID'] = 'eswiki'; in LocalSettings.php file

But get following error in MW 1.35.5

Ops Problem solved I debug error and try for resolve this content_models table in database of Wikibase repo site requirement backup

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: {{#property:q260}} but nothing happen .

Some hints how to configure or use wikidata in mywiki ?

Regards g

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.

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

A third-party client like you want to do it is not possible yet.

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?

Is it possible now? Or not yet? I would like to access to Wikidata data from an external wiki. Is there any workaround? Thanks.

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  :/

It's been a while. Is this possible yet?

Is it possible now? Or not yet?

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?

(note: I invoked that template in the context of Ukrainian Wikipedia)

Lua access is different from API access. Lua access is currently only possible within Commons.

@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?

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.

Hi, I just upgraded to MediaWiki 1.31.0. My repo works fine, however, when I try to load an article on the client wiki, I get the following error:

Sorry! This site is experiencing technical difficulties.

Try waiting a few minutes and reloading.

(Cannot access the database)

The local database can be accessed perfectly, special pages like recent changes or user contributions show up properly, but somehow the repo database can't be accessed anymore :/

Any ideas are more than appreciated! Thanks and cheers!

Did you made sure to run the update.php maintenance script on both the repo and the client database?

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!

• 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.

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:

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!

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.

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

So I added the whole block:

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

	];

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!

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.

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! :)

Cheers!

I wonder I can run mediaWiki 1.32 without database replication?

Alex Lai

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?

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.

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?

All Wiktionaries except English don't yet have arbitrary access enabled. You can file a ticket on phabricator.wikimedia.org to get it enabled.

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.

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?

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?

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".

Then that is where the problem is, because I did not use composer.

After upgrading my site: http://www.hattebol.no/index.php?title=Forside to 1.28.2, my template:infobox person stopped working. So I installed Wikibase Client and repository and created the seemingly missing Properties. Still I can't get rid of the display of the missing parameters in the template. See http://www.hattebol.no/index.php?title=Mal%3AInfoboks_biografi

At this point Wikibase requires more up-to-date code than MediaWiki 1.28.2. Have you tried installing the latest code from git?

Lydia,

I have now tried ver. 1.29.0 and 1.30.0-alpha (from Git) with the same result.
