Wiki PageID
by Gintautas Sulskus 05 Oct '18

05 Oct '18

Hi, I have a couple of questions regarding the Wiki Page ID. Does it always stay unique for the page, where the page itself is just a placeholder for any kind of information that might change over time? Consider the following cases: 1. The first time someone creates page "Moon" it is assigned ID=1. If at some point the page is renamed to "The_Moon", the ID=1 remains intact. Is this correct? 2. What if we have page "Moon" with ID=1. Someone creates a second-page "The_Moon" with ID=2. Is it possible that page "Moon" is transformed into a redirect? Then, "Moon" would be redirecting to page "The_Moon"? 3. Is it possible for page "Moon" to become a category "Category:Moon" with the same ID=1? Thanks, Gintas

We plan to drop the wb_entity_per_page table
by hoo 01 Jun '17

01 Jun '17

Hey folks, we plan to drop the wb_entity_per_page table sometime soon[0], because it is just not required (as we will likely always have a programmatic mapping from entity id to page title) and it does not supported non -numeric entity ids as it is now. Due to this removing it is a blocker for the commons metadata. Is anybody using that for their tools (on tool labs)? If so, please tell us so that we can give you instructions and a longer grace period to update your scripts. Cheers, Marius [0]: https://phabricator.wikimedia.org/T95685

Problems installing Wikibase repository and client in the same site
by Iván Hernández Cazorla 15 May '17

15 May '17

Hi everyone! I am trying to configure Wikibase in a wiki that I have installed. I want to use both, repository and client. I have followed installation instructions <https://www.mediawiki.org/wiki/Wikibase/Installation>, but I think that I made something wrong because now I have several errors in my wiki. If I access to any page of the site I see "Internal error", the error and the backtrace. For example, in the mainpage: [e837b2d7a6fcc7e1edaead2a] /Portada Error from line 240 of /[PATH]/extensions/Wikibase/client/includes/Store/Sql/DirectSqlStore.php: Class 'Wikimedia\Rdbms\SessionConsistentConnectionManager' not found It also happens when I try to edit any page in main namespace. Then, another error is when I visit the page Special:CreateItem: [1d904eb6d5d155e0d0c710ae] /Especial:CreateItem TypeError from line 32 of /[PATH]/extensions/Wikibase/repo/includes/Store/Sql/SqlIdGenerator.php: Argument 1 passed to Wikibase\SqlIdGenerator::__construct() must be an instance of Wikimedia\Rdbms\LoadBalancer, instance of LoadBalancer given, called in/[PATH]/extensions/Wikibase/repo/includes/Store/Sql/SqlStore.php on line 298 You can check my settings for Wikibase in that gist <https://gist.github.com/distriker/6a387d967a7b48e36f41055f00c3c366>. But I have made is config both extensions in the same file and the namespaces like as explain the advanced configuration <https://www.mediawiki.org/wiki/Extension:Wikibase_Repository#Advanced_Confi…>. I have configurated PHP 7. Any idea? Thanks in advance! Regards, Iván -- Iván Hernández Cazorla. Estudiante del Grado de Historia en la *Universidad de Las Palmas de Gran Canaria*.

Wikidata Query Service + Mediawiki API = Love
by Stas Malyshev 09 May '17

09 May '17

Hi! I am developing functionality that will allow WDQS query to get data from Mediawiki API [1]. Currently, the design is as follows: - The API should have a pre-defined template - The template also specifies which results are available from the API The need for template is currently because we need to convert data from API's treelike format to tabular format that SPARQL needs, and the template allows to specify how the conversion is done. See https://www.wikidata.org/wiki/Wikidata:WDQS_and_Mediawiki_API for detailed description of how it works. The prototype implementation is running on http://wdqs-test.wmflabs.org/ (only Categories API described in the page above is configured now, but more will be soon). I'd like to hear feedback about this: - does template model make sense at all? Is it enough? - what APIs would we want to expose? - any other features that would be useful? Other comments and ideas on the matter are of course always welcome. Please comment on the talk page[2] or reply to this message. [1] https://phabricator.wikimedia.org/T148245 [2] https://www.wikidata.org/w/index.php?title=Wikidata_talk:WDQS_and_Mediawiki… Thanks, -- Stas Malyshev smalyshev(a)wikimedia.org

SPARQL query property. Which datatype?
by David Cuenca Tudela 01 May '17

01 May '17

Hi, There is a property proposal to store a SPARQL query equivalent to a category: https://www.wikidata.org/wiki/Wikidata:Property_proposal/Wikidata_SPARQL_qu… I have some doubts about the appropriate datatype. I guess it depends on future plans/community preferences. My ideal scenario would be a datatype "SPARQL query" that would store the plain text and it would be collapsed in the user interface. Users would be able to expand the code or just run it directly. Additionally, queries could be qualified with qualifiers TBD, that would allow to query existing queries, or define how frequently the cached query should be updated. If that would be too much work, then the datatype "string" or a short/long URL to the query seem also valid options. What are your thoughts on the issue? Cheers, Micru

Joining May 29, National Plan Open Science meeting in Delft, The Netherlands
by Egon Willighagen 30 Apr '17

30 Apr '17

Hi Wikidata community, on May 29 in Delft, The Netherlands, the first national meeting is planned for researchers (at a various stage of their career) about the Dutch National Plan Open Science. There will be a large session where organisations and individuals can present their experiences with Open Science... I will join the meeting and want to see Wikidata there, and plan to host a table about Wikidata in research... every since the joined H2020 funding application (which we didn't get), I have been using Wikidata for our interoperabilty work in various research projects... However, the more the merrier, and I'm hoping to co-host a Wikidata table at this meeting... who else is interested in teaming up and showing the Dutch research community how Wikidata can help them with their Open Science? My own work is in the area of the life sciences, but I know many others are using Wikidata for other research fields, and the meeting is for all research, not just the natural sciences... Looking forward to hearing from you, greetings Egon -- E.L.

Script and API module for constraint checks
by Léa Lacroix 28 Apr '17

28 Apr '17

Hello all, In the past few months, the development team has mentored a student, Olga, to help us developing a user script <https://www.wikidata.org/wiki/User:Jonas_Kress_%28WMDE%29/check_constraints…> that displays the constraints on the item pages. To use the script, add the following line to your user/common.js: mw.loader.load( '//www.wikidata.org/w/index.php?title=User:Jonas_Kress_(WMDE)/check_constraints.js&action=raw&ctype=text/javascript' ); You will see an icon [image: Icon used on the user script for constraint reports on Wikidata] <https://commons.wikimedia.org/wiki/File:Constraint_icon.png> next to violations. When you click it you will see the full report. [image: Screenshot of the user script checking constraints on Wikidata] <https://commons.wikimedia.org/wiki/File:Screenshot_constraint_check_Wikidat…> This script is based on a new API module for constraint checks <https://www.wikidata.org/wiki/Special:ApiSandbox#action.3Dwbcheckconstraint…> that one can use to check constraints on items and statements. At the moment, the constraint checks are only derived from the property discussion page constraint templates, not directly from statements. They are then stored in a database table. We are running a script to update this table every now and then or when you ask for it. Also note that some constraint checks are disabled (for example the format check). In the future we will support adding and updating constraints on property statements and we will implement support for some constraints that are currently still missing. If you try it, feel free to give us feedback! You can also add comments or subtasks on Phabricator (see the ticket for the API module <https://phabricator.wikimedia.org/T102757> and the user script <https://phabricator.wikimedia.org/T97018>). If there is no major disagreement, we would like to turn this script into a gadget in the next days. Thanks go to Olga and all the developers that helped her providing this new feature :) See also: - API Documentation <https://www.mediawiki.org/wiki/Wikibase/API#wbcheckconstraints> - Self-documentation for the module <https://www.wikidata.org/w/api.php?action=help&modules=wbcheckconstraints> Cheers, -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.

Sitelink removal in Wikidata
by Amir Ladsgroup 28 Apr '17

28 Apr '17

Hey, One common form of vandalism in Wikidata is removing sitelinks (we already have an abuse filter flagging them). One of my friends in Persian Wikipedia (who is not a wikidata editor and only cares about Persian Wikipedia) asked me to write a tool that lists all Persian Wikipedia sitelink removals. So I wrote something small and fast but it's usable for any wiki. For example English Wikipedia: http://tools.wmflabs.org/dexbot/tools/deleted_sitelinks.php?wiki=enwiki It's slow due to nature of the database query but once it responds, you might find good things to revert. Since this is the most useful for Wikipedia editors who don't want to patrol Wikidata (in that case, this query <https://www.wikidata.org/w/index.php?namespace=&tagfilter=new+editor+removi…> is the most useful) I'm reaching to wider audiences. Sorry for spamming. HTH Best

The strategy discussion. The Cycle 2 will start on May 5
by Szymon Grabarczuk 27 Apr '17

27 Apr '17

The first cycle of the Wikimedia movement strategy process[1] recently concluded. During that period, we were discussing the main directions for the Wikimedia movement over the next 15 years. There are more than *1500* summary statements collected from the various communities, but only *3* from the Wikidata discussion[2]. The strategy facilitators and many volunteers have summarized[3] the discussions of the previous month. A quantitative analysis of the statements will be posted on Meta for translation this week, alongside the report from the Berlin conference[4]. The second cycle will begin soon. It's set to begin on May 5 and run until May 31. During that period, you will be invited to dive into the main topics that emerged in the first cycle, discuss what they mean, which ones are the most important and why, and what their practical implications are. This work will be informed and complemented by research involving new voices that haven’t traditionally been included in strategy discussions, like readers, partners, and experts. Together, we will begin to make sense of all this information and organize it into a meaningful guiding document, which we will all collectively refine during the third and last cycle in June−July. We want to help your community to be more engaged with the discussions in the next cycle. Now, we are looking for volunteers who could - tell us *where to announce* the start of the Cycle 2, and *how to do that*, so we could be sure the majority of your community is informed and has a chance to feel committed, and - facilitate the Cycle 2 discussions on Wikidata. We are looking forward to your feedback!
