Welcome to Wikidata, Christian Ferrer!

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.

Your Commons categoriesEdit

While I will honor your requests to delete your own Commons category items for lack of notability, you should have a chat with James and find out what he has been up to with regard to Commons categories. Mahir256 (talk) 03:33, 1 July 2018 (UTC)

  • I created those categories because I find in that (Commons category=Wikimedia Category) something logical. However I have been aware, since the creation of those item, that they are not notable because they only links to a category on Commons, as per Wikidata:Notability. Although I still find that logical and simpler (Commons category=Wikimedia Category), I try to fix my mistakes, by "mistakes" I mean the creation of not notables items as per the current policy. Sorry if my mistakes give you a little work, there will still be some similar deletion requests but approximately no more than 10 or 20, because my participation here is limited.

    • It's no problem at all. James has been creating items for individual Commons categories en masse lately, so you may find his opinions on things useful. Mahir256 (talk) 04:41, 1 July 2018 (UTC)
      • @Mahir256, Christian Ferrer: From my perspective, I think there are a couple of principles driving where we currently are at:
      (i) It is useful that as many categories on Commons as possible to link to something here, because that enables interwiki links; a wikidata infobox; a translation of what the category "means" into the language of Wikidata, precisely what is going to be needed to start populating Structured Data on Commons file information; and because the link will remove the category from SQL queries etc looking for Commons categories that might be linkable, but have not yet been linked.
      (ii) But it is preferred not to create more items here than are needed, to achieve the above. So the preference is against creating a new category item here, if the sitelink could go straight to a main-item here (currently the situation for about 1.35 million linked Commons categories). But on the other hand, if there is already a category item here (because it links to other wikis), then link the Commons category to that (making sure there is a category's main topic (P301) / topic's main category (P910) linking the category-item to the main-item. And similarly, create a category item here, if it impossible to link the Commons category to the main item because there is a Commons gallery taking priority for that sitelink.
      Yes, in some ways perhaps always linking (Commons category=Wikimedia Category) might have been simpler and logical, as you suggest (it did seem so at one point to the Community), but it would require creating perhaps 2 million additional redundant items, which is 2 million more things to go wrong, an additional burden for both creation and maintenance, without generating any obvious gain, which is why I think it did make sense for the Community to move away from this 'full parallelism' model, to a position where this mechanism is available if required, but discouraged otherwise.
      Hope that seen in these terms the result seems at least reasonably coherent, best wishes, Jheald (talk) 16:16, 2 July 2018 (UTC)
"Commons gallery taking priority for that sitelink" : the issue is there. Galleries should be listed as properties, and categories should take priority for the sitelinks. Christian Ferrer (talk) 17:45, 2 July 2018 (UTC)
That is an idea that has been suggested, most recently by User:Ghouston. The trouble is that that would break the interwiki links back from the gallery to Wikipedias. It also becomes inconsistent, because sometimes one specifically does want the Commons category to link to a category-item, eg to include interwiki links to Wikis or sister projects that have the category but not the article (especially Wikisource). And it's further away from the model that was originally adopted, so a bigger step to gain consensus for. On the whole, I think what we have come to probably as well as anything is going to, and it is what the community currently understands as the consensus. Jheald (talk) 18:05, 2 July 2018 (UTC)

Merging itemsEdit

Hallo Christian Ferrer,
When you (want to) merge items, you may want to use the merge.js gadget from help page about merging. It helps with merging, gives the option to always keep the lower number (which is older, so preferable in most cases) and removes the need to file a request on Wikidata:Requests for deletions.

Fossiles de la collection de Louis AgassizEdit


Je te contacte car je me suis appuyée sur un élément que tu avais créé pour tenter de faire une entrée correcte concernant un fossile, il s'agit de Q73376253. J'essaye d'entrer toutes les données le concernant qui ont été partagées sur Commons par le Muséum d'histoire naturelle de Neuchâtel, qui héberge la collection à laquelle appartient ce fossile.

Je me demandais si tu estimes que l'entrée est correcte, et éventuellement, si tu savais comment ajouter la stratigraphie?

Merci d'avance!--Flor WMCH (talk) 13:58, 3 November 2019 (UTC)

Pour ce dernier point, j'ai posé la question dans Wikidata talk:WikiProject Taxonomy, mais pas sur que j'ai une réponse précise.. Christian Ferrer (talk) 15:11, 3 November 2019 (UTC)
Merci pour ces modifications/précisions, et de m'avoir signalé le WikiProject Taxonomy. Je vais voir s'il y a des réponses pour tenter de faire des entrées claires.--Flor WMCH (talk) 10:25, 4 November 2019 (UTC)
