[Wikidata-l] Wikidata for research - a new WikiProject and a grant proposal
by Daniel Mietchen 05 Dec '14

05 Dec '14

Dear all, I'm interested in making Wikidata more interesting to researchers. To this end, I have started https://www.wikidata.org/wiki/Wikidata:WikiProject_Wikidata_for_research , whose first activity is to draft a proposal for a research grant which would allow researchers to work on this more systematically. Your contributions to this would be much appreciated. For more information, see http://blog.wikimedia.de/2014/12/05/wikidata-for-research-a-grant-proposal-… . Thanks and cheers, Daniel -- http://www.naturkundemuseum-berlin.de/en/institution/mitarbeiter/mietchen-d… https://en.wikipedia.org/wiki/User:Daniel_Mietchen/Publications http://okfn.org http://wikimedia.org

[Wikidata-l] Identifier lookup services
by Dario Taraborelli 05 Dec '14

05 Dec '14

What are best practices to represent in Wikidata alternate services that can be used to look up the same identifier? For example: - a PDB ID can be looked up via PDBe or RCSB. - a Pubmed ID can be looked up via PubMed or EuropePMC etc. Is the expectation that I should add all relevant services as separate Formatter URLs to the corresponding property?

[Wikidata-l] Unicode escapes in Wikidata RDF N-Triples
by KANZAKI Masahide 05 Dec '14

05 Dec '14

Hello, thank you for providing Wikidata RDF. The effort is very much appreciated. I found that Wikidata RDF in N-Triples format has an encoding issue with non ASCII characters. Because RDF 1.1 N-Triples format no longer has 'ASCII only' restriction, it is desirable to use characters directly as in Turtle format, not using Unicode escape sequences (\uHHHH). If, for some reasons, escape is necessary, it should be '\u' followed by Unicode code point, not UTF-8 octets. For example, Kanji character '位' should be '\u4F4D', not '\u00E4\u00BD\u008D'. Current Wikidata RDF NT is provided in the latter form, which makes non ASCII characters garbages. I hope this issue is not very difficult to fix. cheers, -- @prefix : <http://www.kanzaki.com/ns/sig#> . <> :from [:name "KANZAKI Masahide"; :nick "masaka"; :email "mkanzaki(a)gmail.com"].

[Wikidata-l] next IRC office hour for Wikidata
by Lydia Pintscher 04 Dec '14

04 Dec '14

Hey folks :) I'll be doing an office hour on IRC for all things Wikidata. It'll be on December 3rd at 18:00 UTC. We'll be meeting in #wikimedia-office on freenode. Hope to see many of you there!

[Wikidata-l] Loan words data model
by Edward Betts 04 Dec '14

04 Dec '14

Bairro (Q16837104) has the English description: "a Portuguese word that refers to a community or region within a city or municipality". It is a subclass of neighbourhood (Q123705). There are many neighbourhoods in Brazil with the 'instance of' property set to bairro (Q16837104), for example: Gamboa (Q3757943), Riachuelo (Q3934201) and Noal (Q10337174). Q16837104 includes sitelinks to enwiki and trwiki, but not to ptwiki. There is a Bairro article on Portuguese Wikipedia, represented by the Wikidata item neighbourhood (Q123705). It would be useful if bairro (Q16837104) could include a sitelink to the bairro article in Portuguese Wikipedia, but this is forbidden because it is already linked to from another item. In English Wikipedia we have articles describing two concepts, neighbourhood and bairro, but in Portuguese Wikipedia there is only a single article for the concept of neighbourhood. There is another item, barrio (Q1761572), for the Spanish variant of this word. It would be useful if we could add a way to represent loan words in Wikidata. Then we can add a statement that says Bairro (Q16837104) is a loan word of neighbourhood (Q123705) in Portuguese. -- Edward.

[Wikidata-l] statements on properties are live (+deletion propagation)
by Lydia Pintscher 04 Dec '14

04 Dec '14

Hey folks :) We just enabled statements on properties. You can for example use this to: * describe mappings to other projects' vocabularies * indicate constraints for the usage of this property (currently stored in templates on the talk page of the property) * store information about where this property is used in other projects to make sure they can be notified when major changes are made to how the property is used * provide links to extensive documentation about and showcases for the usage of this property * store patterns for how an identifier should be expanded to form a proper URL * ... Some notes: * You can't yet make statements linking to other properties to for example indicate that property X is the inverse of property Y. We are adding a new datatype for that. It'll come soon. The ticket for that is https://phabricator.wikimedia.org/T75302 * Constraint violation reports currently don't take these statements into account. They will continue to use the templates on the property's talk page. A team of students is currently working on overhauling the whole constraint system. It'll take them a while still though. Unrelated but also important for you to know: If a page is deleted on Wikipedia/Commons/... that has a sitelink in an item on Wikidata that link will be removed automatically now.

[Wikidata-l] sneak peek time - checking against 3rd party databases
by Lydia Pintscher 03 Dec '14

03 Dec '14

Hey folks :) The student team working on data quality and trust is hard at work and just showed me a first demo. I wanted to share that with you as well. One part of the team is working on checking Wikidata's data against other databases. Attached is a screenshot of their first demo showing checking of our data against MusicBrainz. In the end this will be nicely integrated on Wikidata as part of the constraint violation reports probably. This is already working way better than I expected it ever would. So heads off to the students. I'm sure they'll kick ass over the next months. Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

Hi Lydia and Wikidatans, Besides the Wikidata Items and Statements' Tutorials here - https://www.wikidata.org/wiki/Wikidata:Tours - when might the other tutorials mentioned on this Wikidata Tours' page - for References, Qualifiers, Ranks, Special Values, for example - be coming, and especially inter-lingually ? Thanks, Scott -- - Scott MacLeod - http://worlduniversityandschool.org

[Wikidata-l] Data access for Commons enabled + reminder for statements on properties
by Lydia Pintscher 02 Dec '14

02 Dec '14

Hey folks :) As announced the week before last we just enabled data access for Commons. This does not yet include access to information from arbitrary items but only the item that is directly connected to the page using the data via a sitelink. Please help with polishing the relevant pages https://commons.wikimedia.org/wiki/Commons:Wikidata and https://www.wikidata.org/wiki/Wikidata:Wikimedia_Commons. What will come later: arbitrary access (in January/February) and storing meta data about individual files (part of the ongoing work on the structured data on Commons project) Tomorrow we will enable statements on properties so you can store mappings to other database vocabularies for example.
