Welcome to Wikidata, Mabschaaf!

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! --Leyo 12:32, 15 February 2013 (UTC)


Hi, my apologies for continuing in English. My German is not so fluent. I had quick look at the point you brought up. It seems to me that the definition in the German Wikipedia is more precise than that in the English one. I also note that the Wikidata item linked to Bleomycin is biased towards that of a specific Bleomycin (A2) and not of the mixture described in the German Wikipedia. I have seen this regularly, and is likely caused by the fact that the English Wikipedia has a ChemBox template. This needs to be cleaned up. I suggest we create a new Wikidata item for the Bleomycin mixture and link the German and other Wikipedia pages for the mixture to that one. And correct the label of Bleomycin (Q415571) to match the A2 form. I will check the CAS numbers related to the things in SciFinder tomorrow. Thank you for bringing this to my attention! --Egon Willighagen (talk) 22:07, 8 December 2018 (UTC)

Your proposal seems to me to be straight forward. Please proceed - I hope we can curate items like this.--Mabschaaf (talk) 23:14, 8 December 2018 (UTC)
OK, step 1: based on the German Wikipedia page for the group of compounds, there is this bleomycins (Q883844), and try this Scholia page. --Egon Willighagen (talk) 07:50, 9 December 2018 (UTC)
Step 2: the drug, which is a mixture is now Bleomycin (Q415571), and the A2 is now bleomycin A2 (Q26841044).
Step 3: identify all bleomycins, but the list on that German Wikipage does not capture stereochemistry for all, and ChEBI only has a small set, and two off that with no structure info. So, this one is going to take a lot longer. --Egon Willighagen (talk) 08:14, 9 December 2018 (UTC)
Well done. I just added the description in german to the items.--Mabschaaf (talk) 09:25, 9 December 2018 (UTC)
Thanks. I'm now looking some of the bleomycins from that German table and using the CAS number to do some derecplication. Confirmed that bleomycin G (Q59580275) (new) does not have stereo in SciFinder and added it without it. --Egon Willighagen (talk) 13:36, 9 December 2018 (UTC)
OK, I think I got all of them, plz see [ this Scholia page. The German Wikipage seems to have the wrong PubChem CID, though. It should be CID6852373, IMHO. I checked the stereochemistry of that one, and that matches the one in SciFinder. --Egon Willighagen (talk) 14:27, 9 December 2018 (UTC)
Thx. I corrected the CID at the German Wikipage.--Mabschaaf (talk) 14:33, 9 December 2018 (UTC)

Taylor Swift - pop star and chemist! - temporary_batch_1546358226259Edit

Is there anything that woman can't do? ;)

I think something might be off with your quickstatements batch, it cites a Taylor Swift track as a reference source for a ECHA InfoCard ID, hehe. Have a look at:

Happy New Year! Moebeus (talk) 16:52, 1 January 2019 (UTC)

Oh dear! Thanks for notifying me, that went really bad. Unfortunately, I do not know how to undo or repair these edits. I will ask User:MisterSynergy who helped me already a lot.--Mabschaaf (talk) 17:18, 1 January 2019 (UTC)
Looks like a very classical Excel mishap during data preparation (select a cell and "copy" it to a range of cells by dragging the value down; unfortunately, Excel increases non-numerical values such as Q-IDs as well). There are almost 1000 items affected; I’ll set up a batch to fix this later this evening, however my family is waiting for dinner which is more important right now… :-) —MisterSynergy (talk) 18:30, 1 January 2019 (UTC)
Your guess hits the bulls eye ;-). Enjoy your dinner, thanks a lot for your help.--Mabschaaf (talk) 19:14, 1 January 2019 (UTC)
The repair batch has just finished.
This is what many (fresh) QuickStatements users experience at some point. Let’s put it like that: it’s been only 1000 items, and it was rather easy to repair. We’ve seen much larger mishaps of the same type … Now back to work ;-) —MisterSynergy (talk) 19:50, 1 January 2019 (UTC)
@MisterSynergy: Ich mache hier mal auf Deutsch weiter (sollte ja kein Problem sein): Ich habe den Eindruck, dass jetzt bei Deiner Reparatur etliche Kollateralschäden entstanden sind. Ein Beispiel: [1] - Dort hast Du die CAS-Nr, EG-Nummer und die ECHA-Infocard-ID jeweils mit dem Verweis auf die ECHA-Datenbank belegt. Hier sogar einschließlich InChlKey. Mein QS-Batch bezog sich allerdings ausschließlich auf Ergänzungen der ECHA-ID.--Mabschaaf (talk) 20:14, 1 January 2019 (UTC)
Nein, das ist Absicht – aber tatsächlich unabhängig von Deinem Batch. Zuerst habe ich Deine 957 Fälle bearbeitet, danach aber welche, die eh nochmal verbessert werden mussten. "stated in (P248): European Chemicals Agency (Q48798)" macht keinen Sinn, da stated in (P248) einen Wert vom Typ "Werk" erwartet (zum Beispiel ECHA InfoCard database (Q59911453)), nicht einen vom Typ "Organisation" wie European Chemicals Agency (Q48798). Deshalb wurde da bisher auch eine Eigenschaftseinschränkungsverletzung angezeigt. Da ich mit demselben Skript wie für die Reparatur auch die anderen Werte korrigieren konnte, habe ich das bei der Gelegenheit gleich hinterher erledigt. —MisterSynergy (talk) 20:42, 1 January 2019 (UTC)
Ah, prima. Diese Fälle hätte ich auch noch auf meiner ToDo-Liste gehabt, aber erst später. Auch die Fundstellenangaben mit der URL der ECHA-Suchmaske sind in meinen Augen nicht besonders hilfreich. Davon könnte ich viele noch mit Angabe der exakten URL präzisieren. Aber dazu irgendwann mehr...--Mabschaaf (talk) 22:45, 1 January 2019 (UTC)
