Logo of Wikidata

Welcome to Wikidata, Markus Krötzsch!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, please ask me on my talk page. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Best regards!

As a matter of fact, I am somewhat familiar with the whole thing already, but thanks for the welcome anyway, and welcome, too, to our little project ;-) --Markus Krötzsch (talk) 13:01, 3 August 2013 (UTC)

OWL, Wikidata, and everythingEdit

Hi Markus, I just replied to your comment in the class-instance RFC. I figured I'd note it here since you made your comment over two weeks ago. Thanks, Emw (talk) 22:33, 5 October 2013 (UTC)

Thanks for the pointer; I added my replies there. --Markus Krötzsch (talk) 17:29, 8 October 2013 (UTC)

another instance/subclass questionEdit

Thanks for your useful comments so far, I was wondering if you could comment on the following case that pops up from WD:PC#spilt birth date(P:P569), death date (P:P570) and coordinates (P:P625)?:

  • homo sapiens is an instance of taxon
  • people are instances of organism because they are instances of homo sapiens
  • homo sapiens is a subclass of taxon

That should mean that Q5 is an instance of taxon (when considered as a set of people) when considered as a conduit between Barack Obama and "organism", right ? You said before that is was all right to use the same item for classes and individuals, but does that make sense in this case ? Is there a risk to confuse reasoning tools ? --Zolo (talk) 08:06, 22 October 2013 (UTC)


I see you have an ORCID iD; please add it to your user page (here and on en:Wikipedia) using {{Authority control}}, as described at en:WP:ORCID. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:28, 11 August 2015 (UTC)

Done (also added a bunch of other ids). --Markus Krötzsch (talk) 11:27, 13 August 2015 (UTC)


exact match (P2888) is ready. --Tobias1984 (talk) 19:31, 5 June 2016 (UTC)

SQID suggestions for relative (P1038)Edit

Hello Markus Krötzsch,

I noticed the tool suggests the addition of grandparents with P1038, based on statements for parents. I don't think this type of statement is welcome. Was there some recent discussion about changing it? If not, could you remove these suggestions? If the suggestion is merely displayed, this would be fine. Obviously, if there is a reference and no trace of the parents, the suggestions would be excellent. --- Jura 10:48, 28 November 2018 (UTC)
