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
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?
we plan to drop the wb_entity_per_page table sometime soon, 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.
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
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
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
Argument 1 passed to Wikibase\SqlIdGenerator::__construct() must be an
instance of Wikimedia\Rdbms\LoadBalancer, instance of LoadBalancer
You can check my settings for Wikibase in that gist
But I have made is config both extensions in the same file and the
namespaces like as explain the advanced configuration
I have configurated PHP 7.
Any idea? Thanks in advance!

I am developing functionality that will allow WDQS query to get data
from Mediawiki API .
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 or reply to this message.
There is a property proposal to store a SPARQL query equivalent to a
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?
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
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,

In the past few months, the development team has mentored a student, Olga,
to help us developing a user script
that displays the constraints on the item pages.
To use the script, add the following line to your user/common.js:
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]
This script is based on a new API module for constraint checks
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
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

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:
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
the most useful) I'm reaching to wider audiences. Sorry for spamming.
Registration is now open for the ‘Celtic Knot’ – Wikipedia Language Conference<https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2017> taking place Thursday 6 July 2017 at the University of Edinburgh Business School.

The University of Edinburgh and Wikimedia UK are delighted to invite you to join us at this event<https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2017> showcasing innovative approaches to open education, open knowledge and open data that support and grow Celtic and Indigenous language communities.
Announcing our keynote speakers
* Jason Evans<https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2017#Keynotes> - Wikimedian in Residence at the National Library of Wales<https://wikimedia.org.uk/wiki/Expert_outreach/Wikipedian_in_Residence_at_th…>, now the longest running Wikimedia residency in the World. Jason has been responsible for implementing and leading a number of innovative projects designed to increase public and institutional engagement with Wikimedia projects. A passionate advocate for open access, he has published case studies and produced a business case on the subject, drawing on the successful implementation of open access policies at The National Library of Wales. Jason has spoken widely of the importance of the Welsh language Wikipedia and the multilingual nature of Wikidata in developing Welsh as a digital language and has recently began exploring the use of multilingual data to create Welsh language Wikipedia content.
* Professor Antonella Sorace<https://wikimedia.org.uk/wiki/Celtic_Knot_Conference_2017#Keynotes> - Professor of Developmental Linguistics at the University of Edinburgh<http://www.lel.ed.ac.uk/%7Eantonell/> and founding director of Bilingualism Matters<http://www.bilingualism-matters.org.uk/>. Antonella is a world leading authority on bilingualism over the lifespan and is particularly well known for her studies of exceptionally talented ("near-native") adult second language speakers; for her research on the changes ("attrition") that take place in the native language of advanced second language speakers; for her investigation of bilingual language acquisition in early and late childhood, and of the effects of bilingualism in non-linguistic domains.
Confirmed speakers also include:
* Robin Owain<http://www.bbc.co.uk/news/uk-wales-north-west-wales-23402054> – Wales Manager for Wikimedia UK
* Astrid Carlsen – Executive Director, Wikimedia Norge<http://www.wikimedia.no/en/about-us/>.
