[Wikidata-l] New stuff! (ordering, ranks and a table of content)
by Lydia Pintscher 12 Dec '13

12 Dec '13

Hey everyone, After a few hick-ups ordering, ranks and a table of content for item pages are now live on wikidata.org together with a load of other small improvements. I hope you enjoy them. There are still a few usability issues with ordering as well as the problem of ordering changes not showing up in diffs. If you find any other issues related to this deployment that do not go away after reloading/purging(add ?action=purge to the URL) the page please let me know.

[Wikidata-l] Distributing the Wikipedia category/pagelink graph

[Wikidata-l] Wikidata RDF Dumps
by Kingsley Idehen 08 Dec '13

08 Dec '13

All, We've just commissioned the latest edition of the Linked Open Data (LOD) Cloud cache that we maintain [1]. As part of this effort, we included Wikidata's RDF dumps and Freebase cross references. Thus far, I am not convinced that we've actually loaded all of data out there, so I am seeking some help from those associated with the production of the following: 1. Wikidata dumps -- basic 2. Wikidata dumps -- with cross references to Freebase. To understand my concerns, here are some sample links: [1] http://bit.ly/1hDhexC -- random Wikidata entity description of one "Stephen Fry" [2] http://bit.ly/1aMwpvU -- another description of the same entity (this time from the Freebase dump which cross references Wikidata). Links: [1] http://lod.openlinksw.com -- home page. [2] http://lod.openlinksw.com/sparql -- SPARQL endpoint. -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Company Web: http://www.openlinksw.com Personal Weblog: http://www.openlinksw.com/blog/~kidehen Twitter Profile: https://twitter.com/kidehen Google+ Profile: https://plus.google.com/+KingsleyIdehen/about LinkedIn Profile: http://www.linkedin.com/in/kidehen

[Wikidata-l] XML Prague 2014
by Innovimax SARL 07 Dec '13

07 Dec '13

Dear WikidataLovers, In the process of organizing, the 2014 edition of XML Prague, I thought it might be interesting to cross bridges between Wikidata and XML Prague As an organizers of the conference, I wanted to see the opportunities of proposing interesting XML challenge to the XML communities via Wikidata Also, we are also interetested in advanced use of XML from WikidataLovers, that could lead to a presentation, a poster or an intervention in a hands on session. Prague is a lovely city and we will do our best to make it confortable. We don't have much money (conference fees are very cheap) but we can invite people and help them finding accomodation. The conference will be held on 14-16th February 2014 Best regards, Mohamed ZERGAOUI on behalf of XML Prague Organizers http://xmlprague.cz -- Innovimax SARL Consulting, Training & XML Development 9, impasse des Orteaux 75020 Paris Tel : +33 9 52 475787 Fax : +33 1 4356 1746 http://www.innovimax.fr RCS Paris 488.018.631 SARL au capital de 10.000 €

[Wikidata-l] new features available for testing (ranks, ordering, table of contents and more)
by Lydia Pintscher 06 Dec '13

06 Dec '13

Hey everyone! We deployed a bunch of new code to test.wikidata.org for you to test. Based on your feedback for the initial version of quantities I have decided to not release them to wikidata.org next week. We have been working on a good part of the feedback and most fixes are now also live on test.wikidata.org. This means quantities are now scheduled to come to Wikidata in the middle of January. I'm sorry for the delay but your feedback was very valuable. In addition to that we have rolled out a new batch of features to test.wikidata.org for you to test and give feedback on. The first one is ordering. You can now change the order of statements and statement groups. There are still a few usability issues with it that we need to solve but I want to get this out to you now. The second one is ranks. Ranks are there to indicate one or more statements are preferred or deprecated. This is especially useful for things like indicating that someone was the major of a city many years ago. The third one is a table of contents that was developed by Bene*. This should come in handy especially on large items. The forth one is that the data type of a property is now also added to the JSON and API output. And last but not least we've worked on improving performance so things run a bit faster for you. These should go live on wikidata.org on Tuesday next week. So how's that for a Christmas present, people? ;-) Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

[Wikidata-l] Italian Wikipedia complements search results with Wikidata based functionality
by Gerard Meijssen 06 Dec '13

06 Dec '13

Hoi, The Italian Wikipedia is the first project where people who use search will find results added from Wikidata. As you may know, Wikidata knows has more items with a label in a language than a Wikipedia has articles. With the Wikidata based functionality people will gain several functionalities that are new to them - a link to Commons categories for a subject - a link to Wikipedia articles in other languages - a link to the Wikidata item - visualisation care of the "Reasonator" When there are multiple items found in the search request, disambiguation will be provided based on the statements available on the items. Obviously as more labels are available in a language for statements, the experience will improve. This is a really exciting new development and I want to thank Magnus and Nemo for making it possible. I hope and expect that many Wikipedias will follow the example of the Italian Wikipedia. Particularly the smaller Wikipedias have much to gain from this new functionality. Thanks, GerardM

[Wikidata-l] Collaboration with scholarly resources?
by Daniel Mietchen 05 Dec '13

05 Dec '13

Dear all, I am exploring options of interaction between Wikidata and scholarly resources. While my focus here is on biodiversity research (and I'd be very happy to hear about your activities along these lines), a more concrete route for collaboration now becomes visible with PubChem, as mentioned at https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Chemistry#Collabora… . Cheers, Daniel
