Welcome to Wikidata, Edgar181!

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, don't hesitate to ask on Project chat. 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.

DrugBank edit

Hi Edgar, you changed the Drugbank-ID of vecuronium bromide (Q27108523) to "SALTxxx". In fact, this is correct - but despite, the created URL to the corresponding Drugbank entry is https://www.drugbank.ca/drugs/DBSALT001200. This means, DrugBank ID (P715) was never intended to be filled with any "SALT" identifiers. In my opinion, we should have either another property for these or we should add the "DB" to all pure numbers used as IDs right now and create the corresponding URL without any letters after https://www.drugbank.ca/drugs/.--Mabschaaf (talk) 07:05, 6 July 2019 (UTC)Reply

I think adding DB to the number in that property would be a good idea. The issue was raised at Property talk:P715 by User:Wostr, so maybe the discussion can be continued there. Edgar181 (talk) 11:57, 6 July 2019 (UTC)Reply

chemical messes edit

Hi Edgar181, since you seem to be able to clean up problem chemical entries in Wikidata, I will alert you to these problems that are mostly duplicates: Q7843939 dup of Q56232384; Q27187515 and Q17299987; Q27163260 and Q6554803 Graeme Bartlett (talk) 00:57, 21 November 2019 (UTC)Reply

I agree that Q7843939 and Q56232384 are duplicates, so I have merged them. However, Wikidata considers chemical compounds with undefined isomerism (or a mixture of isomers) as distinct items from chemical compounds that are specified isomers. In the cases of Q27187515/Q17299987 and Q27163260/Q6554803, one item is an unspecified isomeric mixture and the other is a specified isomer, so I think they belong as separate items and I have adjusted them to make it a bit more clear (I hope).
