Welcome to Wikidata, Speravir!

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.

P2580Edit

User:Jura1 changed the definitions and broken links to the site. Please, get id back, all was worked well Arachn0 (talk) 21:07, 16 March 2019 (UTC)

I made some changes according to my own research. — Speravir (talk– 23:02, 16 March 2019 (UTC)

User:Arachn0 is correct, everything was fine and all IDs and links worked correctly. Whether an ID is valid/invalid has nothing to do with the format. VIAF IDs also come in different formats, but are all stored in one property. The property now links to a pirate site from the USA, which copied content copyrighted by the Baltic Historic Commission. They don't have content for each of the BBLD IDs. Jura1 also replaced valid BBLD IDs with invalid BBLD IDs breaking links in the German, Russian and maybe other Wikipedias that rely on P2580.
