Jour fixe

It has been proposed to have a weekly jour fixe on Thursdays 21:30 CET (a time equally (in)convenient to all our teams around the world). FactGrid has an open web channel for such purposes that can be used without further passwords and software downloads. Contact for link details.


Note that the new QuickStatements Version has an annoying security feature implemented on regular user accounts: If you press "Run" you will receive loads of errors after the 90th edit. To avoid this you must use the "Run in background" option.

We hope we can get this obstacle removed, but for the time being we run the platform with Wikidata-settings. --Olaf Simons (talk) 12:24, 13 March 2023 (CET)

  • 16 Jul. 2023: New on our blog (in German but you will know how to get it translated): Eckard Rolf's classification of non-literary text types to be used on the "Type of work property" P121: The entire vocabulary is so far a test case of a first structured "controlled" vocabulary. The English, French and Spanish versions of the terms still need to be checked, English is 60% checked, French and Spanish basically machine translated. See for the synopsis.

You will need to be logged in to see the “add statement” link with which you can add information in the form of triple based machine readable claims — which everyone can now explore with the SPARQL data mining language, at our Query Service.

The FactGrid database is an open collaborative and multilingual project organised by — as of May 2024 — 433 participants / by language / by gender from all over the world. If you are looking for a site to present research data and keep them in the process of further research — the FactGrid database might be a cool candidate.
