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!

Merging itemsEdit

Hallo DGtal,

When you are merging items, please use the Merge.js gadget. It helps you nominating, gives the option to always keep the lower number (which is older, so preferable) and makes it a lot easier for the admins to process the requests.

With regards, -      - (Cycn/talk) 12:13, 11 December 2013 (UTC)

Hi, I have used the gadget ever since I discovered it exactly as you recommended. The last request was caused by a one time bug. Thanks, DGtal (talk) 12:47, 11 December 2013 (UTC)

Thanks for bookmobile (Q720920)  View with Reasonator View with SQID !Edit

Hi DGtal! You may add some help tools to user:DGtal/common.js or (if you use the vector skin) to user:DGtal/vector.js . Please see User:Rotsaert8000 (in Esperanto), Wikidata:Tools, and Wikidata:Tools/User scripts for candidates you may add. On the user:i18n-page you will see all WD gadget links. It takes time to see what fits most of your interests. Good luck! Please feel free to use the Wikidata Sandbox item: Wikidata Sandbox (Q4115189)      for your first steps adding some statements see Wikidata:List of properties. If you want to notify a user you may use {{ping|foo bar}} at any place on this wiki. Regards gangLeri לערי ריינהארט (talk) 22:43, 26 May 2014 (UTC)

Proteins and genes are distinct conceptsEdit

Hi, I noticed a merge on a gene item (Q14820612) and a protein item (Q422301). Although related they are distinct concepts and as such should not be merged. A protein is a product of a gene. Merges like this leads to incorrect knowledge since it links gene properties to protein properties and vice versa. I took the liberty to revert the merge to the previous state of separate gene item and a separate wikidata item. --Andrawaag (talk) 07:15, 25 October 2015 (UTC)

Thank you Andrawaag. Checking again, I now understand what went wrong. The English-language article en:Secretin talks about the hormone/protein but is linked to the gene item (Q14820612). Could you double check if I am correct, and if I am, we should connect the enwiki article to Q422301 rather than to Q14820612. I humbly await your reply, DGtal (talk) 07:31, 25 October 2015 (UTC)
DGtal , please see the previous discussion on Andra's talk page: https://www.wikidata.org/wiki/User_talk:Andrawaag#ProteinBoxBot_Mistake.3F . Gene's and proteins are highly interrelated things but they are not the same. One gene may encode multiple different proteins with different properties. In the current data model, all of the data is maintained but it is distributed across several related items. --I9606 (talk) 20:39, 26 October 2015 (UTC)

Constraints no longer use the templates on the talk pages, but statements on the property pages. Mbch331 (talk) 09:53, 23 July 2017 (UTC)

Thank you Mbch331. Could you refer me to a correctly stated example of legitimate constraint violations of IMDb ID (P345)? DGtal (talk) 10:15, 23 July 2017 (UTC)
I don't know what you mean, but all constraints are on IMDb ID (P345). Mbch331 (talk) 10:54, 24 July 2017 (UTC)
Now I see what you mean. Thanks, DGtal (talk) 11:29, 24 July 2017 (UTC)



Can you create the article en:Lists of Azerbaijani films, en:Template:Azerbaijan film list and en:List of Azerbaijani film directors in Hebrew?

Can you create the article en:Bodies of water of Azerbaijan in Hebrew?

Can you also create the article en:List of rivers of Azerbaijan in Hebrew?

Thank you.

Sarvathi (talk) 14:33, 28 April 2018 (UTC)

Not really. Hebrew Wikipedia has an uncommon policy of discouraging list articles unless they have an added value, which is not the case with articles that are "just" lists of people, rivers, etc. DGtal (talk) 06:28, 29 April 2018 (UTC)

Wikidata workshop for WikipediansEdit


As part of the activities of Wikimedia Israel to increase awareness, use and integration of Wikidata in Wikipedia, you are invited to a meeting that will include a lecture and editing activities. The meeting will take place on Wednesday, April 3, 2019, from 18:00 to 20:00 at the offices of Wikimedia Israel (Carlebach 7, Tel Aviv).

Please let me know if you can come or sign up on Hebrew Wikipedia Thanks!

Keren - WMIL (talk) 16:32, 26 March 2019 (UTC)



Can you translate and upload en:National Library of Azerbaijan, en:Baku State University and en:Science and technology in Azerbaijan in Hebrew Wikipedia?

They don't need to be long.

Yours sincerely, Matricatria (talk) 10:40, 8 June 2019 (UTC)

Military branchEdit

Hi, since you wondered in your comment why I have removed IDF from the "military branch" property, it is due to the fact the IDF is not a "military branch", it is the Military itself. A military branch is, for example, "Israeli Navy" as correcly indicated here: Q2917441, or "Israeli Air Force", as corectly indicated here: Q2906409. The "military branch" property is misused in relation with Israelis (I see that some even qualify Mossad or Shabak as a "military branch", while those organizations are not a part of the Israeli military), causing the incorrect reflection of the branch in the wikis employing automatic uploading of Wikidata properties. -- Prokurator11 (talk) 15:37, 3 June 2020 (UTC)

Wikidata:WikiProject Star TrekEdit

hey, you might like to join Wikidata:WikiProject Star_Trek --Shisma (talk) 11:12, 22 November 2020 (UTC)

Preprint items - how to address them?Edit


I am unsure how to address preprints. I've seen a comment by you elsewhere and I wanted to get your comment.

I think you would have editors replace scholarly article (Q13442814) with preprint (Q580922). Am I correct in this? It's an extra step when creating article with Source Meta Data (Source MD), but no problem.

Also, I hoped to get your thoughts on how to connect the preprint to the scholarly article. Does one put replaced by (P1366) in the preprint, put replaces (P1365) in the published article, or use some variety of has edition or translation (P747) or modified version of (P5059)? I'm so very confused...

Also, how does one address/edit items that are comments on preprints, e.g. Author's response to referee #1 (Q104586602)? What is the best linkage with preprint, referee's comment, final article, etc.? Now my brain hurts.

Thanks, Trilotat (talk) 16:28, 30 December 2020 (UTC)

I agree we should replace scholarly article (Q13442814) with preprint (Q580922). I think modified version of (P5059) is best here. Regarding the final question, referee's comments should use main subject (P921) to connect to the paper in question. DGtal (talk) 18:47, 30 December 2020 (UTC)
Okay. Thanks for your response. Trilotat (talk) 19:01, 30 December 2020 (UTC)
