This workshop will take place on Fenruary 21st, it's a short activity with high school students of La Spezia. It later expande to another lesson of February, 28th and a third one on March, 21st.

The students will show their expertise with programs such as ChemDraws uploading missing 2D or 3D structural representations of molecules on Wikimedia Commons and articles on English wikipedia.



Please write your name and add a description in your user page here on English Wikipedia.

Proposed tasks[edit]

c:Category:Methyl isobutyrateis an ideal example of a molecule with a category on commons where both 2D (vectorial) and 3D representations can be found. Let's try to get this coverage for other molecules, uploading what is missing.

(I will clean up their work this evening)--Alexmar983 (talk) 16:01, 21 February 2019 (UTC)

commons categories[edit]

Exercise description[edit]

Please remember:

  • check the IUPAC name in English;
  • add it to the file with the "+" sign, once saved you will see it red;
  • Please don't just copy and paste the name of a file as it is, use the IUPAC name;
  • remove previous categories if are the future parent categories of your new one;
  • click on the red link, insert the [[category:]] code for the parent category;
  • the parent category is usually already used in the file, you are replacing with a more specific one;
  • "publish" (blue button)

Examples for the class - first lesson:

Examples for the class - second lesson:

  • Meconic acid.svg, (example 3)  Done
  • category:18-Methoxycoronaridine molecule, show the corrections in front of the students

First lesson[edit]

this was also created as "Category:2-Ethyl-2-oxazolin aus Propionaldehyd" copying the full name of a file by User:Lory03. I asked to delete the wrong name.--Alexmar983 (talk) 20:31, 21 February 2019 (UTC)
good, but you put the same category as a parent category, I add later a new one.--Alexmar983 (talk) 20:30, 21 February 2019 (UTC)
created as "Category:2-Aminomuconic-acido-zwitterion-3D-balls" name of the file, deleted. it still has to be created.--Alexmar983 (talk) 20:36, 21 February 2019 (UTC)
Still missing--Alexmar983 (talk) 20:36, 21 February 2019 (UTC)
Done as "Category:1-Methylnaphthalene 3D" and deleted see. Still can be created.--Alexmar983 (talk) 20:42, 21 February 2019 (UTC)
inserted as a red link, still missing--Alexmar983 (talk) 20:45, 21 February 2019 (UTC)
actually 2-methylpropene is c:Category:Isobutylene so there is no need to create it.
This has no sense to be created, toluol is another name of c:Category:Toluene (it's probably German, like Benzol for benzene)--Alexmar983 (talk) 20:45, 21 February 2019 (UTC)
why there is "molecule" in the title? The category is the IUPAC name or the most common name, so that shuld be "category:18-Methoxycoronaridine". We fix it at the lesson. I must fix it now, we will make a nother example nest lesson.--Alexmar983 (talk) 21:17, 28 February 2019 (UTC)
parent categories improved
this is not the IUPAC name, it was made as a redirect to c:Category:1-methylcyclopropene (already existing)--Alexmar983 (talk) 14:24, 6 March 2019 (UTC)

Second lesson - group 1[edit]

Users who tried to made a category but did a mistake. I reassigned the same category (if it has sense) so it can be completed.

for: user:Nikidelcarro02, c:category:2-Aminomuconic-acid  Done
ok, not bad but you removed form the files some categories that are not related to the chemistry of functional groups (for example "created by user X" or "stick and balls"). Such categories are related to the single file. Please pay more attention to the meaining of what you are removing and pasting. Also, you put the "Category:2-Aminomuconic-acid" twice.--Alexmar983 (talk) 14:30, 25 March 2019 (UTC)
for: user:Rosy Oliviero  Done
for: User:Chiaretta002  Done

Second lesson - group 2[edit]

Users who haven't saved a category yet.

For User:Dario.frumento
Still missing.--Alexmar983 (talk) 21:04, 25 March 2019 (UTC)
For User:Sanna Diego  Done
more precise category--Alexmar983 (talk) 08:40, 27 March 2019 (UTC)
For User:Angelo Sanguineti
 Done With typo--Alexmar983 (talk) 17:49, 7 April 2019 (UTC)
For User: Giuliamonti23  Done
it was saved as "3-Diaminoacrolein_Struktur", I told you to pay attention to use ONLY the molecule name as a name. I am delelting the wrong category.--Alexmar983 (talk) 21:07, 25 March 2019 (UTC)
For User: GalleniChiara
For User:ElisaCastiglione  Done
For User:Edoardo.cerutti02
For User:Thomaschelo02
For User:RiccardoCarini02  Done
For User:Julia.fersini  Done
it was created correctly but with ho parent categories, and also with a wrong name but correct parent category.--Alexmar983 (talk) 22:23, 15 April 2019 (UTC)
For user:Paulettapietro02 Done
For User:SteleaRadu0  Done
For User:Simone benabbi02  Done
ok, but please notice that User:JWBE is the one who completed the insertion of the category on the other files.--Alexmar983 (talk) 08:02, 27 March 2019 (UTC)

Second lesson - group 3[edit]

Users who did a category at the first lesson try to do another one:

For User:Antonio.Torzulli
For User:Martina.avino
It was created by User:Antonio.Torzulli but he put the same category as its parent category. I fixed also the generic categories which were left there--Alexmar983 (talk) 11:10, 27 March 2019 (UTC)
For User:GalleniChiara
For User:SteleaRadu0
It was marked as  Done but I don't think it is correct.--Alexmar983 (talk) 21:53, 25 March 2019 (UTC)
For user:Greco Cristian
For user:Lucamanga02
Not done (but he did the first lesson)--Alexmar983 (talk) 10:32, 8 April 2019 (UTC)
For User:Lory03
Not done.--Alexmar983 (talk) 13:04, 11 April 2019 (UTC)

Second lesson - group 4[edit]

You are not on the list of students yet? Are you free and completed your task? Do another one...

For User:Edoardo.cerutti02
c:category:Oct-1-yne done in the 3d image sections, which is confused but overall it was a good job.

Second lesson - group 5[edit]

More exercises. These examples are mostly drugs (with shorter non-IUPAC names). We don't use the IUPAC name since it is a drug, but it could be interesting to have it.

missing svg files[edit]

Since we are not sure about the quality of svg files, we put this aspect on hold and we focus on missing 3D images.

missing 3D images[edit]

Find missing 3D images. One possible way:

  • open a wikipedia article of a chemical coumpund (search in the bar for 1-nitro, 2-methyl, 1-ethyl, 1,2-di and so on);
  • check those without 3D representation;
  • click on the other existing image (usually 2D representation in the infobox);
  • go on such image file on Wikimedia Commons through the blue botton at the lower right corner;
  • access the commons category (categories are on the last line of the Commons file, at the bottom of the page);
  • check if a 3D image exists in such category;
  • if it does not, please write here that it is missing.

molecules with a specific commons category - group 1[edit]

They also have an article on English Wikipedia

molecules with a specific commons category - group 2[edit]

They also have an article on German Wikipedia

done by User:GalleniChiara
that was probably my mistake, it's already connected.--Alexmar983 (talk) 20:28, 17 April 2019 (UTC)
you linked to the wrong one fixed but it's not your fault, in the item the English translation was in faxt missing.--Alexmar983 (talk) 20:15, 17 April 2019 (UTC)

molecules with a specific commons category - group 3[edit]

They have article on Italian Wikipedia

molecules with a specific commons category - group 4[edit]

They have no article on any Wikipedia

that was my mistake, it seems the 3D exists--Alexmar983 (talk) 19:52, 7 April 2019 (UTC)
not categorized--Alexmar983 (talk) 19:52, 7 April 2019 (UTC)

Uploaded images[edit]


Wikidata Infoboxes[edit]

If we have time we show how to insert Wikidata Infoboxes with additional information to these categories. For this task you will edit on both commons and wikidata.


Examples for the class:



  • add {{Wikidata Infobox}} in the commons category source code
  • please fill the summary line (campo oggetto) if you can
  • the infobox appears and it's empty before adding the link on wikidata
  • search for the wikidata item through the article on wikipedia or through the search bar on wikidata.
  • please on the search bar don't put "category:X" but "X".
  • please look carefully at the item you want to link, read the first line after the language description table, where the key property "instance of" appears. Is it "chemical compound"? For example
d:Q54261715 and d:Q2567814, do you see the difference?
d:Q414101 and d:Q42389878, do you see the difference?
  • add the link to commons on the wikidata item in the section at the end of the page. Put "commons" on the right and "category:X" on the box of the left.

For this task, we assigned one user to each molecule.

group 1[edit]

Newly created categories during the first lesson (see first section). The creators can do this task directly on their previous work.

already  Done by me as an example, sorry --Alexmar983 (talk) 12:28, 1 March 2019 (UTC)
inserted on wikidata, not the infobox.--Alexmar983 (talk) 18:22, 11 April 2019 (UTC)
done by User:Edoardo.cerutti02--Alexmar983 (talk) 18:24, 11 April 2019 (UTC)
done as IP.--Alexmar983 (talk) 18:24, 11 April 2019 (UTC)
not done.--Alexmar983 (talk) 20:24, 17 April 2019 (UTC)

group 2[edit]

Other categories presented for the second (and third) lesson:

dona as IP.--Alexmar983 (talk) 23:47, 13 April 2019 (UTC)
you linked to d:Q28027821 which is the item of "category:estranes". This is a link of all the categories including derivatives. You should have searched "estrane" instead of "category:estrane" on the search bar You link "category:X" but on the bar you search for X.

group 3[edit]

Are you not on the list of students yet? have you already performed the task and you'd like to do more? Please take a look at these entries:

group 4[edit]

Would you like to do another one? help yourself!

group 5[edit]

For the third lesson, with only on-line supervision (March, 6th). Please find here more exercise if you need them.

you created a totally new item. I merged it with the actual correct item.--Alexmar983 (talk) 21:56, 9 March 2019 (UTC)
you created a totally new item. I merged it with the actual correct item.--Alexmar983 (talk) 21:57, 9 March 2019 (UTC)

Wikidata welcome message[edit]

For the third lesson, AFTER all users have created a link commons-wikidata (previous exercise) please insert the welcome message on wikidata talk page.

For example User_talk:Sanna_Diego is the page for discussion here on English Wikipedia. Welcome messages contains key information for new users and some tutorials.

If you take a look I left you all a message on your talk page here, but you have not used yet. So you will now leave one on wikidata too.

You will all leave a message in a talk page of another user. The current link goes to the non existing page, as you can see the ":d:" stands for the link to wikidata, the link apperas blue and not red because it's a link to another platform. Only links to empty page on the same platform appears red. these pages are in any case empty and they still need to be created.

Click on "create" (at the left of the search bar in the right corner). The code to copy and paste in the blank page is this one:


Paste it in the blank page, than "publish change".

Next time I am there we will discuss what the code means.--Alexmar983 (talk) 13:29, 6 March 2019 (UTC)

not done, the talk page is still red.
