[Breaking Change Announcement] Changes to the wblistentityusage API module
by Mohammed Sadat Abdulai 03 May '23

03 May '23

Hello! This is a breaking change announcement regarding the WikibaseClient wblistentityusage API module. This API module is used for listing all pages that make use of data from a given entity via Lua, parser functions, or Sitelinks. Currently, this API module has two issues: - When using this module as a value for the list parameter in an API query action, the results are added to the query.pages key in the response object. However, this key is reserved for use with the following parameters: generator, titles, pageids, and revids. This could lead to a collision if used alongside one of these parameters, potentially causing a runtime exception. - The API parameter prefix wbeu is shared between list=wblistentityusage and prop=wbentityusage (a different module that instead lists all entities used on a given page). However, the module prefix must be globally unique. We are addressing both issues at the time. Starting today, you can use the wblistentityusage API with the parameter prefix wbleu instead of wbeu, and the results will be added under query.entityusage instead of query.pages. However, the old prefix (wbeu) is still supported for some time, and will continue to produce the same output as before (with an additional deprecation warning). On or shortly after 2023-05-17, we will remove support for the old prefix and output format from the API. Thus, you now have two weeks to migrate to the new prefix and output format. For a comparison between the old and new methods of using the API, please refer to the wbeu version <https://test.wikidata.org/w/api.php?action=query&list=wblistentityusage&wbe…> and wbleu version <https://test.wikidata.org/w/api.php?action=query&list=wblistentityusage&wbl…> examples. If you have any questions or concerns about this change, please don’t hesitate to reach out to us via tickets T196962 <https://phabricator.wikimedia.org/T196962> or T300460 <https://phabricator.wikimedia.org/T300460>.

Request to whitelist domain for CORS
by admin＠hindibox.co.in 02 Apr '23

02 Apr '23

Dear Wikidata API team, I am writing to request that you whitelist my domain, hindibox.co.in, for Cross-Origin Resource Sharing (CORS). I am currently working on a project that requires fetching data from the Wikidata API, but I am encountering the "Cross-Origin Request Blocked" error due to the Same-Origin Policy. I have tried using the https://cors-anywhere.herokuapp.com proxy to bypass this issue, but I am now getting a 403 error. After researching this issue, I found that the best solution is to request that my domain be added to your CORS whitelist. I would greatly appreciate it if you could add hindibox.co.in to your CORS whitelist so that I can continue working on my project. Please let me know if there is any additional information or steps that I need to take to make this happen. Thank you for your attention to this matter. Best regards, Hindibox Team

by Olaf Simons 01 Apr '23

01 Apr '23

Dear all, on FactGrid wikibase I created some 300 Items with erroneous Wikidata sitelinks. Is there a way to remove these sitelinks or to overwrite them with the correct Wikidata references using QuickStatements?

The first version of the new Wikibase REST API is now available on Wikidata
by Lydia Pintscher 25 Jan '23

25 Jan '23

Hi everyone, We are working on making it easier to use Wikidata's data to build applications. A big part of that is a better API. Over the past months we have been developing the first version and gotten testing and feedback for it. Last week we made it available on test.wikidata.org. Today the first version of the new Wikibase REST API is available on Wikidata. I'd like to thank everyone who helped along the way by providing feedback and testing. You can find more information on what you can already do with the new Wikibase REST API at https://www.wikidata.org/wiki/Wikidata:REST_API. We will continue to build out its functionality and your input on what would be most useful for you will help prioritize the next steps. Please leave your thoughts at https://www.wikidata.org/wiki/Wikidata_talk:REST_API_feedback_round#The_Wik….

The Wikibase REST API is now available for testing on Test.Wikidata
by Mohammed Sadat Abdulai 18 Jan '23

18 Jan '23

*(apologies for cross posting)* Hello everyone, As you may already know, we are developing a new REST API to improve programmatic access to data from Wikidata and other Wikibase instances. Many thanks to everyone who gave us the initial feedback on the proposed implementation plan of the REST API and subsequently tested the experimental phase of it on Beta Wikidata <https://wikidata.beta.wmflabs.org>. All the items listed in our previous communication <https://lists.wikimedia.org/hyperkitty/list/wikidata@lists.wikimedia.org/me…> as still needing to be completed for the initial release have now been completed and we are pleased to announce that the Wikibase REST API is planned to go live on Wikidata about a week later. What is the current state capable of doing? - Retrieve the data of an Item with ‘GET /entities/items/{item_id}’ and filter what fields (i.e. type, labels, descriptions, aliases, statements, sitelinks) are returned when reading the Item data - Retrieve all statements of an Item with ‘GET /entities/items/{item_id}/statements’ - Retrieve the data of a single statement of an Item with ‘GET /entities/items/{item_id}/statements/{statement_id}’ or ‘GET /statements/{statement_id}’ - Conditionally request the data only if it has changed since the specified revision/timestamp (using If-None-Match, If-Modified-Since HTTP headers) - Create a statement on an Item with ‘POST /entities/items/{item_id}/statements’ - Authenticate and authorize as a Beta Wikidata user when making edits using the API, as well as provide edit tags and edit comment, and mark an edit as one made by a bot. - Replacing the statement on an Item with ‘PUT /entities/items/{item_id}/statements/{statement_id}’ or ‘PUT /statements/{statement_id}’ - Removing the statement from an Item with ‘DELETE /entities/items/{item_id}/statements/{statement_id}’ or ‘DELETE /statements/{statement_id}’ - Automated edit summaries The following functionality is still awaiting a final security review of a library <https://phabricator.wikimedia.org/T316523> and will be enabled once that is finished: - Editing a statement on an Item with ‘PATCH /entities/items/{item_id}/statements/{statement_id}’ or ‘PATCH /statements/{statement_id}’ Please note that the following items previously listed under "The following will likely not be available in the first version but follow later" have not yet been finished and will not be available in this initial release: - Creating or deleting an Item - Getting a statement from an Item based on the Property ID in the statement - Any operation (reading, adding, editing, removing) on sitelinks, labels, descriptions and aliases - Any operation on entity types other than Items (i.e. Properties, Lexemes, …) - Translated error messages However, we will continue to work on these items in the future to provide a more comprehensive REST API. In order to prioritize our next steps, we would greatly appreciate feedback on which missing features you would find most useful to add next. If you have any questions or want to provide feedback please let us know at Wikidata talk:REST API feedback round <https://www.wikidata.org/wiki/Wikidata_talk:REST_API_feedback_round#The_Wik…>. As this new API is more tailored to the Wikibase data model than the Action API, we have outlined the differences in the JSON data format between the two <https://doc.wikimedia.org/Wikibase/master/php/rest_data_format_differences.…> for you for easy comparison. Thank you for your patience and support as we continue to improve the Wikibase REST API. Cheers, -- Mohammed Sadat *Community Communications Manager, Wikidata* Wikimedia Deutschland e.

runBlazegraph logging
by Roberto Guido 20 Oct '22

20 Oct '22

Hi. I'm setting up a local instance of Wikidata, but have a particular issue: ./runBlazegraph.sh produces tons of logging, most labelled as "DEBUG", and I've found no documentation about the parameters to use to suppress it (or, at least, to use a different logging level). Adding -Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog -Dorg.eclipse.jetty.LEVEL=WARN to the "exec java" command has reduced a bit the output, but still it reacts to ./loadRestAPI.sh with an insane quantity of debugging informations (which, of course, has heavy impact on performance). Any advice on it? Thank you. -- Roberto Guido http://www.madbob.org/

Wikibase suite: wmde.7, and wmde.8, security release updates, 1.35, 1.36
by Mohammed Sadat Abdulai 13 Sep '22

13 Sep '22

*(apologies for cross-posting)* Hello, We’re pleased to announce security and maintenance updates for Wikibase Suite that are compatible with MediaWiki 1.35 and 1.36. These updates, which include the release of new container images, take the form of two new Suite versions: wmde.7 and wmde.8, respectively. Release wmde.7 includes two security fixes for issues in the Wikibase extension: - Validate term length in Special:NewProperty (phab:T308659 <https://phabricator.wikimedia.org/T308659>) - Escape message in hook handler (phab:T302215) <https://phabricator.wikimedia.org/T302215> Note that wmde.8 release is based on Mediawiki version 1.36 which is no longer maintained. We provide this update for technical reasons, as updating to the most recent 1.36-compatible Wikibase version will be needed to update Wikibase to Mediawiki 1.37. WMDE will be releasing that new version shortly. The wmde.8 release includes a fix for the “Escape message in hook handler” issue (phab:T302215 <https://phabricator.wikimedia.org/T302215>). Both releases also include minor updates, such as translation updates for MediaWiki and the Wikibase and WikibaseLocalMedia extensions, as well as the Query Service UI and Quick Statements. For update instructions, see Upgrading Wikibase <https://github.com/wmde/wikibase-release-pipeline/blob/main/docs/topics/upg…> . If you have any questions, please feel free to ask on this mailing list, or you can leave a comment at Talk:Wikibase/FAQ <https://www.mediawiki.org/wiki/Talk:Wikibase/FAQ>.

You can now check out the current development state of the upcoming REST API for Wikibase
by Mohammed Sadat Abdulai 01 Aug '22

01 Aug '22

Hello everyone, We are working on making it easier to access Wikidata’s data programmatically so that more people can build great applications on top of our data. As part of this we are building a new REST API for Wikibase. A while ago we asked for feedback on the draft specification for that new API <https://www.wikidata.org/wiki/Wikidata:REST_API_feedback_round> (see previous communication <https://lists.wikimedia.org/hyperkitty/list/wikidata@lists.wikimedia.org/me…> ). It is in development now. While it is not in the state which we would like to run on Wikidata, you can now have a look at the current development state on Beta Wikidata <https://wikidata.beta.wmflabs.org> and follow along as we build out the API. You can find the current state of the specification we are working from at https://doc.wikimedia.org/Wikibase/master/js/rest-api/. *(Small caveat: The specification might sometimes be slightly ahead of the code development and contain functionality that still needs to be implemented.)* Please note that the API is still in the experimental development state. There might be changes in the functionality available and API’s behavior that we will not announce separately. The current state can already do the following: - Retrieve the data of an Item with ‘GET /entities/items/{item_id}’ and filter what fields (i.e. type, labels, descriptions, aliases, statements, sitelinks) are returned when reading the Item data - Retrieve all statements of an Item with ‘GET /entities/items/{item_id}/statements’ - Retrieve the data of a single statement of an Item with ‘GET /entities/items/{item_id}/statements/{statement_id}’ or ‘GET /statements/{statement_id}’ - Conditionally request the data only if it has changed since the specified revision/timestamp (using If-None-Match, If-Modified-Since HTTP headers) - Create a statement on an Item with ‘POST /entities/items/{item_id}/statements’ - Authenticate and authorize as a Beta Wikidata user when making edits using the API, as well as provide edit tags and edit comment, and mark an edit as one made by a bot. If you want to give it a try, here are some REST API calls for an example Item (“house cat”) on Beta Wikidata: - Get the complete data of the Item: GET https://wikidata.beta.wmflabs.org/w/rest.php/wikibase/v0/entities/items/Q59… - Get all labels: GET https://wikidata.beta.wmflabs.org/w/rest.php/wikibase/v0/entities/items/Q59… - Get a specific statement by its ID: GET https://wikidata.beta.wmflabs.org/w/rest.php/wikibase/v0/entities/items/Q59… - Get all statements: GET https://wikidata.beta.wmflabs.org/w/rest.php/wikibase/v0/entities/items/Q59… The following things are still missing before it can go live on Wikidata in a first version: - Replacing the statement on an Item with ‘PUT /entities/items/{item_id}/statements/{statement_id}’ or ‘PUT /statements/{statement_id}’ - Editing a statement on an Item with ‘PATCH /entities/items/{item_id}/statements/{statement_id}’ or ‘PATCH /statements/{statement_id}’ - Removing the statement from an Item with ‘DELETE /entities/items/{item_id}/statements/{statement_id}’ or ‘DELETE /statements/{statement_id}’ - Automated edit summaries The following will likely not be available in the first version but follow later: - Creating or deleting an Item - Getting a statement from an Item based on the Property ID in the statement - Any operation (reading, adding, editing, removing) on sitelinks, labels, descriptions and aliases - Any operation on entity types other than Items (i.e. Properties, Lexemes, …) - Translated error messages If you have any feedback on what’s there so far please let us know at Wikidata talk:REST API feedback round <https://www.wikidata.org/wiki/Wikidata_talk:REST_API_feedback_round>.
