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

BREAKING CHANGE: sitelink encoding changing in RDF export/WDQS
by Stas Malyshev 30 Jun '17

30 Jun '17

Hi! In RDF exports of Wikidata[1] and in Wikidata Query Service, sitelinks were always encoded by url-encoding the sitelink text - i.e. link to "Category:Stuffed animals" were encoded as /wiki/Category%3AStuffed%20animals. While this encoding produces a working link, after some time we've arrived to a conclusion that such encoding is very inconvenient, due to mismatch with how titles are encoded in Mediawiki, and this mismatch makes it harder to look up the links. See more in https://phabricator.wikimedia.org/T131960 We have decided to change the encoding, so that the encoding of the sitelink above would be /wiki/Category:Stuffed_animals. The encoding now should match how titles are encoded in Mediawiki codebase (non-ASCII characters that Mediawiki encodes will still be encoded as before). Implementation of this change will require database reload, and during that time there might be inconsistent results returned for some time (some entities may have new sitelink encoding and some the old one). I apologize in advance for any inconvenience caused by that. I will announce additionally when the switch is process has started and when it is complete. Thanks, [1] https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format -- Stas Malyshev smalyshev(a)wikimedia.org

Include data from a connected Wikibase item
by Iván Hernández Cazorla 01 Jun '17

01 Jun '17

Hi everyone, I am trying to include data from a Wikibase item in a page with *{{#property:P2}}*. For that I need to link the page with the item, as in Wikidata, add a sitelink. However, I don't know how to link a page with my local repository, because in the sitelinks section I only see the options to add a sitelink of a Wikimedia's wiki. You can check the attached image to see what I see. I didn't find useful documentation to solve it. Could anyone help me? Thanks in advance. Regards, Iván -- Iván Hernández Cazorla.

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

Property to group other properties
by Thad Guidry 26 May '17

26 May '17

In my last email regarding Law properties, I noticed that we have many very specific properties, but only a handful of generic properties, probably for good reason. But there are semantic use cases to group together conceptual properties that adhere to a parent concept. Is there a property that groups or clusters properties themselves ? Say that I want to cluster or group together properties that exhibit a form of "Applies". "applies to territorial jurisdiction" https://www.wikidata.org/wiki/Property:P1001 "applies to part" https://www.wikidata.org/wiki/Property:P518 "applies to taxon" https://www.wikidata.org/wiki/Property:P2352 So besides "See also" https://www.wikidata.org/wiki/Property:P1659 and "subject item of this property" https://www.wikidata.org/wiki/Property:P1629 ... What else is available to help group or cluster properties ? -Thad +ThadGuidry <https://www.google.com/+ThadGuidry>

Fwd: [Wikimedia-l] Wikimedia genealogy and historical research software - a proposal for HRE
by Pine W 24 May '17

24 May '17

Perhaps this would interest some Wikidatans and software developers. Pine ---------- Forwarded message ---------- From: Michael Maggs <Michael(a)maggs.name> Date: Wed, May 24, 2017 at 7:58 AM Subject: [Wikimedia-l] Wikimedia genealogy and historical research software - a proposal for HRE To: "Discussion about the Wikimedia genealogy project." < wikimedia-genealogy(a)lists.wikimedia.org>, Wikimedia Mailing List < wikimedia-l(a)lists.wikimedia.org> Cc: John Lubbock <wikimediauk-l(a)lists.wikimedia.org> There has been quite bit of discussion over the years about how the Wikimedia movement could engage with those who have research interests in family history or genealogy, and a centralised discussion page [1] has been set up on Meta. I am posting to ask whether there would be Wikimedian developers who would be interested in joining an open source project to create a free platform independent application called History Research Environment [2] (‘HRE’) for the serious genealogist or historical researcher. Considerable effort has been put into high-level planning over several years, and we are now ready to start writing code. While the proposed software is not currently an official Wikimedia project, if there is enough interest we are open to it becoming integrated or affiliated in some way. The plan is, in any event, that the software should be interoperable with Wikidata to allow (subject to the agreement of the Wikidata community) the exchange of a variety of structured data including verified and fully sourced family trees. I'd be happy to answer queries.
