Welcome to Wikidata, Matthias M.!

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.

Best regards!

Properties for review

I saw that you contribute to the chemistry task force. Do you have time to look at Crystal habit, Twinning, Fracture and Cleavage? (link) --Tobias1984 (talk) 17:15, 19 May 2013 (UTC)

User:Orci is the inorganic expert here. Matthias M. (talk) 18:03, 19 May 2013 (UTC)

Some organic crystals also have macroscopic properties (e.g. aspirin, sugar, ...). I will also ask Orci, thanks. --Tobias1984 (talk) 18:20, 19 May 2013 (UTC)

Creating scripts for properties

Hi Matthias, I'm also a Mattia (in Italian)! I've seen that you've created scripts to automate the insertions of certain properties; I've proposed some property additions, which have already been approved, mainly concerning movies, TV series and anime (and annexes such as character IDs, company IDs and person IDs), but now that are active it would be useful to populate it! I would therefore like to ask you if you could give me some lessons on customising your script for my proposed properties (e.g. TheTVDB movie ID). I'm not a code expert but I'm not a novice either! If you could help me out by telling me which lines I should customise, I could manage on my own (I hope!) for the remaining properties. --Wiccio (talk) 08:43, 10 February 2024 (UTC)

Take my schnittberichte.py as an example. Delete the OGDB functions as TVDB does not seem to link that in the "Other Sites" section. Then customize both the DatabaseEntry and the IMDB section, especially the BeautifulSoup which parses the HTML. You can use ChatGPT to generate the XPath/Regex based on the website source code for you. For testing, keep the IDs to loop through at the bottom small. After bug fixing and refinement, you can increase it. If you get a stable script, and it turns out to be a long-running task with many IDs, take a look at wikitech:Help:Toolforge/Running Pywikibot scripts so you don't have to run it on your own computer the whole time.

Thank you @Matthias M. for the initial information but I think I overestimated myself! I have many gaps on how to proceed! If you'd like to help me, I'll summarise what I've done so far. I installed Python3, then starting from your schnittberichte.py I adapted my thetvdb.py (is the code correct?). Meanwhile on Toolforge I got myself enabled as a maintainer and opened the thetvdbot tool page. Now I should import my python code here, right? I couldn't do it, despite having installed PuTTY and having followed all the steps for creating SSH keys (I can currently log in correctly and enter the tool with the become command). I also didn't understand whether I should proceed with the OAuth request. --Wiccio (talk) 16:25, 19 February 2024 (UTC)

If you are not sure if your code is correct, you have to run it locally and carefully monitor the results. Matthias M. (talk) 17:26, 19 February 2024 (UTC)

indie game (Q2762504)

Your edit of the item have resulted in hundreds of constraint errors Trade (talk) 00:26, 4 March 2024 (UTC)

Should be fixed now. Matthias M. (talk) 20:14, 4 March 2024 (UTC)

Official website

Hi, could you please not remove the official website (P856) for a software project, even if it happens to be the same as their page on GitHub, Sourceforge, Savannah, etc.? Often a software project is present on multiple sites, but there is one that the project considers to be its official presence and is updated regularly, and the others are often out of date. Or they use GitHub as their main presence, but just keep around Sourceforge for the mailing list. Also official website (P856) is used by Wikipedia and others, which often don't show the other identifiers like SourceForge project (P2209), and even if they did there is no way to indicate which of those is considered to be the project's official presence. Thanks. –LiberatorG (talk) 00:10, 14 May 2024 (UTC)

On Wikipedia, it should also use Template:SourceForge (Q11055330) and Template:GitHub (Q14940522) instead of Template:Official website (Q5614958) which is the wrong semantic. Those are project sites, not websites. A project may not have a separate website which is also fine. Matthias M. (talk) 05:12, 14 May 2024 (UTC)

The project site meets the definition of a website. But regardless of what you want to call it, the official web presence for the project is one of the most important properties for a software project, as it is the official source of truth for current information about the project and the go-to place to fact check any claims. How are you suggesting to get this important property if not from official website (P856), considering that many projects exist on multiple sites and often many of them are not kept up to date? The templates that you mention are on Wikipedia; the point of Wikidata is that if something like the official website needs to be updated, that can be done in Wikidata and you don't need to go and edit several Wikipedia articles in languages that you don't understand, or other places that can just pull it from Wikidata. –LiberatorG (talk) 17:17, 14 May 2024 (UTC)

Identifier imports

I have noticed the many identifier imports you have done recently − I tried indexing them at Wikidata:WikiProject_Video_games/Log#May_5, for reference − that’s really great job! Very happy to see that :) (Also happy to see someone else uses maintains linking to (P10568) ;) )

One note regarding the imports: while the source is in the edit summary, would it be possible to also a reference on the statement − using either stated in (P248) or matched by identifier from (P11797)?

(perhaps I mentioned that to you before and you already answered it was not possible, apologies if that’s the case and I don’t recall ^_^')

Thanks again and keep up the great work! Jean-Fred (talk) 18:51, 19 May 2024 (UTC)

Thanks for noticing. I usually don't only use one property to match but all that are available it is just that some like Mobygames are much more abundant and always generate the first hit. Adding a reference is both redundant and bloat. I sometimes see tools referencing with the link itself. The identifier is correct even without the reference. Oftentimes multiple sites link an identifier and then showing a single hit would also be wrong. I just skip when there is already a property. I however state the source in claim creation so it is transparent in the history. You can find a log about my activity in the commit history together with the source code at Wikimedia Gitlab.
