Hey folks :) Here's the summary of what happened around Wikidata over the last week. Discussions - Zero error rate <https://www.wikidata.org/wiki/Wikidata:Project_chat#Zero_error_rate> - help improve the quality of Wikidata's data Events <https://www.wikidata.org/wiki/Wikidata:Events>/Press/Blogs <https://www.wikidata.org/wiki/Wikidata:Press_coverage> <https://commons.wikimedia.org/wiki/File:Wikidata_at_the_ODIAwards_4Nov_082.…> Sir Nigel Shadbolt, Lydia, Magnus and Sir Tim Berners-Lee at the ODI award gala - Wikidata won the Open Data Award by the Open Data Institute in the category Publisher \o/ (blog post by ODI <http://theodi.org/news/first-odi-open-data-awards-presented-by-sir-tim-bern…>, blog post by WMDE <http://blog.wikimedia.de/2014/11/05/zwei-jahre-wikidata-eine-feier-mit-gesc…> ) - Tutorial: Create instant location based timelines using Wikidata queries <http://www.histropedia.com/blog/tutorial-create-instant-location-based-time…> Did you know? - Less than 23% of Wikidata items have no statement.

(Remaining bugs before roll-out are issues with adding/editing/removing statements on property pages.) - Further improvements to sitelink editing (The edit toolbar now floats so it doesn't scroll out of the page on a long list of sitelinks. An empty row for adding a new sitelink is shown by default when editing to make this faster and take less scrolling.) - Further adapting of simple query code so we can get it to review at the Foundation again. - Lots of bug fixes all over the place See current sprint items <http://sb.wmflabs.org/p/wikidata/> for what we’re working on next.

[Wikidata-l] Querying Arbitrary Wikibase Installations

by Derric Atzrott

Hello all, I'm thinking of setting up an installation of Wikibase here at my work to allow folks to store data about things that they work on. Pretty regularly I am tasked with the creation of databases and interfaces for those databases and I suspect that doing this will save me time, make things easier for all of my users, and plus we get revision control for free. I know how to use the Wikidata API to query for information on an individual Wikidata item, but if I want to perform the equivalent of a SELECT statement on a number of Wikidata items (for example to get a list of all items with a particular Instance Of value), how would I go about that? So far it's looking like I am going to need to install the Wikibase Query Engine and the Ask library? https://github.com/wmde/Ask Any help would be appreciated, it looks like Wikibase documentation for reusers is not terribly great yet. After I set things up I'm happy to write a post on my website and create a page on Mediawiki.org to serve as a walkthrough for future users. Thank you, Derric Atzrott Computer Specialist Alizee Pathology

[Wikidata-l] Another birthday gift: SPARQL queries in the browser over Wikidata RDF dumps using Linked Data Fragments

by Cristian Consonni

Dear all, I wanted to join in and give my birthday present to Wikidata (I am a little bit late, though!) (also, honestly, I didn't recall it was Wikidata's birthday, but it is a nice occasion :P) Here it is: http://wikidataldf.com What is LDF? LDF stands for Linked Data Fragments, they are a new system for query RDF datasets that stands middle way between having a SPARQL endpoint and downloading the whole thing. More formally LDF is «a publishing method [for RDF datasets] that allows efficient offloading of query execution from servers to clients through a lightweight partitioning strategy. It enables servers to maintain availability rates as high as any regular HTTP server, allowing querying to scale reliably to much larger numbers of clients»[1]. This system was devised Ruben Verborgh, Miel Vander Sande and Pieter Colpaert at Multimedia Lab (Ghent University) in Ghent, Belgium. You can read more about it: http://linkeddatafragments.org/ What is Wikidata LDF? Using the software by Verborgh et al. I have setup the website http://wikidataldf.com that contains: * an interface to navigate in the RDF data and query them using the Triple Pattern Fragments client * a web client where you can compose and execute SPARQL queries This is not, strictly speaking, a SPARQL endpoint (not all the SPARQL standard is implemented and it is slower, but it should be more reliable, if you are interested in details, please do read more at the link above). The data are, for the moment, limited to the sitelinks dump but I am working towards adding the other dump. I have taken the Wikidata RDF dumps as of Oct, 13th 2014[2]. To use them I had to convert them in HDT format[3a][3b], using the hdt-cpp library[3c] (devel) (which is taking quite a lot of resources and computing time for the whole dumps, that's the reason why I haven't published the rest yet ^_^). DBpedia has also this[4]: http://fragments.dbpedia.org/ All the software used is available under the MIT license on the LDF repo on github[5a], and also the (two pages) website is available here[5b]. I would like to thank Ruben for his feedback and his presentation about LDF at SpazioDati in Trento, Italy (here's the slides[6]). All this said, happy birthday Wikidata.

[Wikidata-l] Surname property

by Jean-Baptiste Pressac

Hello, Claims with surname properties are sometimes impossible. For instance, I tried to add the surname of René Grivart <https://www.wikidata.org/wiki/Q18330867>, but as I typed "Grivart" in the property value, the "save" link stays unclickable. Should we systematically create an item associated with the surname ?

Hi folks, This is just to let you know that I will run live demos for the tutorial at the Unicode conference today between 1 p.m. and 2.30 p.m. Pacific Standard Time. I kindly ask you not to overload the DBpedia endpoint (especially http://dbpedia.org/sparql). Also, I kindly ask the OpenLink guys to have an eye on it if something is not responding well.

[Wikidata-l] Google Code-In 2014: Become a mentor and add tasks!

by Andre Klapper

Hi Wikidata crew, Google Code-In (GCI) will soon take place again - a contest for 13-17 year old students to contribute to free software projects. Wikimedia wants to take part again. Last year's GCI results were surprisingly good - see https://www.mediawiki.org/wiki/Google_Code-in_2013 We need your help: 1) Go to https://www.mediawiki.org/wiki/Google_Code-in_2014#Mentors.27_corner and read the information there. If something is unclear, ask! 2) Add yourself to the table of mentors on https://www.mediawiki.org/wiki/Google_Code-in_2014#Contacting_Wikimedia_men… - the more mentors are listed the better our chances are that Google accepts us. 3) Please take ten minutes and go through open recent tickets in https://bugzilla.wikimedia.org in your area of interest. If you see self-contained, non-controversial issues with a clear approach which you can recommend to new developers and would mentor: Add the task to https://www.mediawiki.org/wiki/Google_Code-in_2014#Proposed_tasks Until Sunday November 12th, we need at least five tasks from each of these categories (plus some less technical beginner tasks as well): * Code: Tasks related to writing or refactoring code * Documentation/Training: Tasks related to creating/editing documents and helping others learn more - no translation tasks * Outreach/research: Tasks related to community management, outreach/marketing, or studying problems and recommending solutions * Quality Assurance: Tasks related to testing and ensuring code is of high quality * User Interface: Tasks related to user experience research or user interface design and interaction Google wants every organization to have 100+ tasks available on December 1st. Last year, we had 273 tasks in the end. Note that you could also create rather generic tasks, for example fixing two interface messages from the list of dependencies of https://bugzilla.wikimedia.org/show_bug.cgi?id=38638 Helpful Bugzilla links: * Reports that were proposed for GCI last year and are still open: https://bugzilla.wikimedia.org/buglist.cgi?quicksearch=ALL%20whiteboard%3Ag… * Open Wikidata tickets created in the last six months (if I got your products and components right): https://bugzilla.wikimedia.org/buglist.cgi?bug_status=UNCONFIRMED&bug_statu… * 8 existing Wikidata "easy" tickets (are they still valid? Are they really self-contained, non-controversial issues with a clear approach? Could some of them be GCI tasks that you would mentor? If so, please tag them as described above!): https://bugzilla.wikimedia.org/buglist.cgi?bug_status=UNCONFIRMED&bug_statu… Could you imagine mentoring some of these tasks? Thank you for your help in reaching out to new contributors and making GCI a success again! Please ask if you have questions. Cheers, andre PS: And in a future Phabricator world, Bugzilla tickets with the 'easy' keyword will become Phabricator tasks with the 'easy' project. -- Andre Klapper | Wikimedia Bugwrangler http://blogs.gnome.org/aklapper/
