Merged Items as Property Targets in Statements
by Miguel Paraz 21 May '17

21 May '17

Hi! I see that when I use the Java API to add a Statement with a Property pointing to an Item, but the Item has been merged: org.wikidata.wdtk.wikibaseapi.apierrors.MediaWikiApiErrorException: [modification-failed] [[Item:Q1040|Q1040]] not found at org.wikidata.wdtk.wikibaseapi.apierrors.MediaWikiApiErrorHandler.throwMediaWikiApiErrorException(MediaWikiAp iErrorHandler.java:62) Is there a way to put in Items such that Wikibase would point them to the merge target? Or, do I need to use the API to find out the merge target so I could use that instead? Thanks! Cheers Miguel

Timestamp of change in user rights
by Cristina Sarasua 05 May '17

Hi, Is there a way to programmatically read the timestamp that indicates when Wikidata editors changed their user rights? I would like to query the edit history dump or the API to know when someone becomes a bureaucrat or an administrator. Thanks in advance, Cristina -- Cristina Sarasua Institute for Web Science and Technologies (WeST) Universität Koblenz-Landau Universitätsstraße 1 56070 Koblenz Germany e-mail: csarasua(a)uni-koblenz.de phone: +49 261 287 2772 fax: +49 261 287 100 2772 web site: http://west.uni-koblenz.de

Significant change: new data type for tabular data files
by Léa Lacroix 02 May '17

02 May '17

Hello all, We’ve been working on a new data type that allows you to link to the *tabular data files <https://www.mediawiki.org/wiki/Help:Tabular_Data>* that are now stored on Commons. This data type will be deployed on Wikidata on *May 15th* . The property creators will be able to create properties with this tabular data type by selecting “tabular data” in the data type list. When the property is created, you can use it in statements, and when filling the value, if you start typing a string, you can choose the name of a file in the list of what exists on Commons. Before the deployment, you can test it on http://test.wikidata.org (example <https://test.wikidata.org/wiki/Q59992>). One thing to note: We currently do not export statements that use this datatype to RDF. They can therefore not be queried in the Wikidata Query Service. The reason is that we are still waiting for tabular data files to get stable URIs. This is handled in this ticket <https://phabricator.wikimedia.org/T161527>. If you have any question, feel free to ask! -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.
