Is there any additional guidance around access to statement values when using federated properties? From the Wikidata guide (arbitrary access): https://www.wikidata.org/wiki/Wikidata:How_to_use_data_on_Wikimedia_projects if I try #statements:P31|from=Q1 (curly brackets left out) P31 can't be found, despite existing in Wikidata's Properties and being completed on my Q1 entity as "company". The error: Failed to render property P31: P31 property not found.
Talk:Wikibase
I installed this extension once and this happened: first all good, I could create items, properties, etc. But at some point it stopped working, I couldn't do anything anymore, the button to add declarations didn't appear, even the special pages to set labels and descriptions didn't work either.
Now that I have re-installed the extension on the same wiki, the exact same thing happened. I don't know what I'm doing wrong, and I know that this is not enough to know the problem, but I don't know what else to do.
We need some more information in order to help you with this problem. Could you provide the version numbers of MediaWiki and Wikibase, which install instructions you used, the output from the relevant MediaWiki logs, and a more detailed description of the failures, including screenshots if possible?

Hello all,
Is there any way to delete all Wikibase entries? something like (SQL command or similar)
Thank you
the file deleteAllData.php does not exist
Are you looking to delete all data? or only Wikibase entities? Are you looking to do a MediaWiki "delete" or rather totally remove all references from you database? What's the usecase?
how can one make a new item an instance of "X", where "X" is something like a class (in OOP terms), a schema (think XML) or a table structure (think RDBMS) so that it gets (the possibility of having) a given set of properties from the start and can perhaps be validated? It seems to me that without a complex datatype, for instance the entity Berlin will be just an amorphous something, and one will have to turn Berlin into a property to be able to make it a city.
How can one reuse the structure of an existing item as a basis for creating a new, similar item?
At Wikidata:WikiProject Books/Book data model, the data model for a book requires the presence of the property "instance of". This of course is fairly easily understod by humans, but does it mean anything to the framework? And if so, how? It is my understanding that inheritance is not supported. I spent a day reading about Wikibase concepts but still have not found any clear answers.
Could anyone please advise why this is happening?

Does this help? Wikibase/FAQ/en#Why doesn't the query service update?
This is the error I receive when trying to "Add links" to a page through Wikibase in MediaWiki 1.35.
Is there any way to improve the error message we receive, to help with troubleshooting?
I'm afraid this needs much more context. Is this on wikidata.org or your own wiki? Do you see anything in the JavaScript console?
Hello, Thiemo.
It's in a wiki I am helping run.
I checked the console and found these errors, which may help find out what causes it:
"Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource" https://shared.prolewiki.org/api.php?action=query&format=json&origin=https%3A%2F%2Fen.prolewiki.org&meta=userinfo(Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
If we try to access that link, we get
"'origin' parameter does not match Origin header"
I'm afraid I can't help with that. I suggest to check if Manual:CORS is helpful.
I'd bet this has nothing to do with Wikidata. Have you gone through the sitelinks documentation here? Wikibase/Installation#Enable Sitelinks
Hi, when I was installing wikibase 1.35.0 that I've downloaded from GitHub (wikibase 1.35.0-wmf.41) (link: https://github.com/wikimedia/mediawiki-extensions-Wikibase/tree/wmf/1.35.0-wmf.41) for mediawiki 1.35.0, while I was doing the final installation process (which is to run the setup scripts like "php maintenance/update.php", it gives me this error: "PHP Fatal error: Interface 'MediaWiki\Hook\ResourceLoaderRegisterModulesHook' not found in D:\Bitnami\mediawiki-1.35.0-0\apps\mediawiki\htdocs\extensions\Wikibase\lib\includes\LibHooks.php on line 20"
Is there a solution to it?
By the ways, I'm using Bitnami MediaWiki Stack that utilizes version 1.35.0.
These versions are not compatible, I'm afraid. I believe you should follow the instructions here: Wikibase/Installation#Download archive.

Thank you
It looks like the version of the GeoData extension you are using is not compatible with the version of the Wikibase extension you are running. The method in the error message is available since release 1.35.0-wmf.2 and in all later releases. You should make sure your GeoData extension is at least this version.
why is there no datatype property in sense objects?
wikidata.org/wiki/Special:EntityData/L99.json
senses:
claims:
- datavalue:
value: "Balloons in the sky.jpg"
type: "string"
property: "P18"
snaktype: "value"
for comparison a regular entity looks like this:
wikidata.org/wiki/Special:EntityData/Q643435.json
claims:
- datatype: "commonsMedia" # ← I need this for sense properties
datavalue:
value: "Congrats bqt.jpg"
type: "string"
property: "P18"
snaktype: "value"Could you please file a ticket for this on phabricator.wikimedia.org? Thanks!
