Hello,
This is a significant change announcement relevant for some Wikibase API
users.
What's Changing?
Over the coming weeks, most Wikibase API modules will gain three new
parameters: returnto, returntoquery, and returntoanchor. Additionally,
these API modules may return tempusercreated and tempuserredirect fields in
their responses. These parameters are being added to support user
interaction flows related to IP Masking
<https://meta.wikimedia.org/wiki/IP_Editing:_Privacy_Enhancement_and_Abuse_M…>
.
Who’s Affected?
Only users who use the API to make anonymous edits are affected. If you
don’t use the API to make edits, or if you only make authenticated edits,
you can safely ignore these changes, and disregard the additional API
parameters and response data.
What You Need to Do
If you use the API to make anonymous edits, the response may contain a
tempusercreated string indicating the name of the temporary account that
was created, and a tempuserredirect nullable string. If the tempuserredirect
is not null, you should redirect the user to that URL to complete the setup
for the temporary account. Afterwards, the user will automatically be
returned to the current wiki; you can use the returnto, returntoquery,
and/or returntoanchor parameters in your original API request to control
the title, query, and anchor where the redirect returns to.
If you have any questions or concerns about this change, please don’t
hesitate to reach out to us in this ticket (T357024
<https://phabricator.wikimedia.org/T357024>).
Cheers,

Dear Wikibase/Wikidata Community,
We are trying to understand which database technologies and strategies Wikibase/Wikidata uses for storing, updating, and querying the data (knowledge) it manipulates.
By looking at the documentation<https://wmde.github.io/wikidata-wikibase-architecture/assets/img/03-dataflo…> we understood that RDF is only used for the Wikidata Query Service, but we could not find out exactly how Wikibase/Wikidata stores the information that is translated to RDF during the data dump.
More specifically, we understood that a MySQL (or is it MariaDB?) relational database is used as the key persistence component for most of Wikibase/Wikidata services and that the information that is maintained in this database is periodically exported to multiple formats, including RDF.
In addition, looking at the relational database schema published in the documentation<https://www.mediawiki.org/wiki/Manual:Database_layout> we could not locate tables that are easily mappable to the Wikibase Data Model<https://www.mediawiki.org/wiki/Wikibase/DataModel>.
Thus, we hypothesize that there is some software component (Wikibase Common Data Access?) that dynamically translates the data contained in those tables to Statements, Entities, etc. Is that hypothesis, correct?
If yes, does this software component uses any intermediate storage mechanism for caching those Statements, Entities, ...? Or are those translations always performed at runtime on-the-fly (be it for querying, adding, or updating Statements, Entities, …)?
Finally, we would like to understand more about how Wikidata REST API<https://www.wikidata.org/wiki/Wikidata:REST_API> is implemented:
• In which database are the statements that added/retrieved through it stored? Is it being stored in the central MySQL database or in another database?
• Does it have any support for pagination of statements? For example, if an item has many statements associated with a property, does the API assumes that both the underlying database and the network will support the retrieval of all those statements?
• Are you currently considering implementing the support for more flexible querying of statements, or such requirement has been fully delegated to the Wikidata Query Service?
If there is an updated documentation that could help us answer those questions, could you kindly point us to it? Otherwise, would you be able to share this information with us?

Hello,
This is a breaking change announcement relevant to those working with
Lexeme dumps.
In Lexeme dumps, "senses" and "forms" values, when not empty, are shown as
arrays. When these lists are empty, they are currently displayed as
objects. For example, values with content are displayed in array
format: "senses":[{"id":"L4-S1",...]
but empty values are treated as objects: "senses":{}
However, empty lists should be presented as arrays as well: "senses":[]
In this change, empty lists of forms and senses will be switched from
objects to arrays. This adjustment makes the dumps more consistent and
matches the same way non-empty values are presented. We will roll this
change out on February 8th.
We anticipate the impact of this change to be minimal and harmless for most
use cases. Therefore, we haven't generated a test dump, as it would demand
substantial resources and time. If you have any questions or concerns about
this change, please don’t hesitate to reach out to us in this ticket (
T305660 <https://phabricator.wikimedia.org/T305660>).
Cheers,

Hi,
between 5:30 and 7:10 UTC on 2023/09/27 the WDQS servers running in the
eqiad datacenter have returned results with more than 10 minutes of lag.
This caused bots using MW maxlag [0] to stop functioning properly during
that time.
The incident started after a failure of the mirroring system between two of
our kafka clusters [1], such incident should not have impacted WDQS but it
uncovered improper sandboxing of the WDQS updater test setup [2].
Sorry for the inconvenience.

Hello all,
Sorry for cross-posting.
The Technical Decision-Making Forum Retrospective
<https://www.mediawiki.org/wiki/Technical_decision_making> team invites you
to join one of our “listening sessions” about the Wikimedia's technical
decision-making processes.
We are running the listening sessions to provide a venue for people to tell
us about their experience, thoughts, and needs regarding the process of
making technical decisions across the Wikimedia technical spaces. This
complements the survey
<https://wikimediafoundation.limesurvey.net/885471?lang=en>, which closed
on August 7.
Who should participate in the listening sessions?
People who do technical work that relies on software maintained by the
Wikimedia Foundation (WMF) or affiliates. If you contribute code to
MediaWiki or extensions used by Wikimedia, or you maintain gadgets or tools
that rely on WMF infrastructure, and you want to tell us more than could be
expressed through the survey, the listening sessions are for you.
How can I take part in a listening session?
There will be four sessions on two days, to accommodate all time zones. The
two first sessions are scheduled:
- Wednesday, September 13, 14:00 – 14:50 UTC
<https://zonestamp.toolforge.org/1694613630>
- Wednesday, September 13, 20:00 – 20:50 UTC
<https://zonestamp.toolforge.org/1694635220>
The sessions will be held on the Zoom platform.
If you want to participate, please sign up for the one you want to attend: <
https://www.mediawiki.org/wiki/Technical_decision_making/Listening_Sessions>.
If none of the times work for you, please leave a message on the talk page.
It will help us schedule the two last sessions.
The sessions will be held in English. If you want to participate but you
are not comfortable speaking English, please say so when signing up so that
we can provide interpretation services.
The sessions will be recorded and transcribed so we can later go back and
extract all relevant information. The recordings and transcripts will not
be made public, except for anonymized summaries of the outcomes.
What will the Retrospective Team do with the information?
The retrospective team will collect the input provided through the survey,
the listening sessions and other means, and will publish an anonymized
summary that will help leadership make decisions about the future of the
process.
In the listening sessions, we particularly hope to gather information on
the general needs and perceptions about decision-making in our technical
spaces. This will help us understand what kind of decisions happen in the
spaces, who is involved, who is impacted, and how to adjust our processes
accordingly.
Are the listening sessions the best way to participate?
The primary way for us to gather information about people’s needs and wants
with respect to technical decision making was the survey
<https://wikimediafoundation.limesurvey.net/885471?lang=en>. The listening
sessions are an important addition that provides a venue for free form
conversations, so we can learn about aspects that do not fit well with the
structure of the survey.
In addition to the listening sessions and the survey, there are two more
ways to share your thoughts about technical decision making: You can post
on the talk page
<https://www.mediawiki.org/wiki/Talk:Technical_decision_making/Technical_Dec…>,
or you can send an email to <tdf-retro-2023(a)lists.wikimedia.org>.
Where can I find more information?
There are several places where you can find more information about the
Technical Decision-Making Process Retrospective:
