Significant change: new data type for tabular data files

by Léa Lacroix

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.

SPARQL query property. Which datatype?

by David Cuenca Tudela

Hi, There is a property proposal to store a SPARQL query equivalent to a category: https://www.wikidata.org/wiki/Wikidata:Property_proposal/Wikidata_SPARQL_qu… I have some doubts about the appropriate datatype. I guess it depends on future plans/community preferences. My ideal scenario would be a datatype "SPARQL query" that would store the plain text and it would be collapsed in the user interface. Users would be able to expand the code or just run it directly. Additionally, queries could be qualified with qualifiers TBD, that would allow to query existing queries, or define how frequently the cached query should be updated. If that would be too much work, then the datatype "string" or a short/long URL to the query seem also valid options. What are your thoughts on the issue? Cheers, Micru
