Welcome to Wikidata, Wolbo!
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.

Short URL link edit
If a SPARQL query is run you can create a "Short URL to result". Is the link persistent or time-limited? If I make a small change to the query will it create a new short URL?--Wolbo (talk) 13:15, 6 February 2021 (UTC)
- Persistent. The short URL links to the query URL as it was at the time you caused the creation of the short URL. Changes made to the query after causing the short URL to be created, will not be found if the short URL is used. Neither is a new short URL created automatically in such circumstances, unless you go through the process of causing a new short URL to be created. --Tagishsimon (talk) 13:20, 6 February 2021 (UTC)
- That's good to know, thanks. Two follow-up questions. It seems the variable part of the URL is only the three characters after https://w.wiki/ eg https://w.wiki/y2U. With all those queries run (must surely be millions) how does the URL link stay unique? Also it seems the URL link defaults to the table view of the query result. Is it possible to create a direct URL link to e.g. the timeline or map view of a query? --Wolbo (talk) 13:45, 6 February 2021 (UTC)
- As to the first, short URLs are created (in WDQS) only when the user selects Link / Short URL to result. As to the second, you can create a short URL for any wikimedia URL at https://meta.wikimedia.org/wiki/Special:UrlShortener - and there is more info on the service at https://meta.wikimedia.org/wiki/Wikimedia_URL_Shortener ... so you could copy the URL of a WDQS query such that you're taken to the WDQS UI or - I presume - to a timeline or other specific visualiation. I think the salient difference is the embed.html part of the URL - which takes you to the result, versus no embed.html which takes you to the WDQS UI.

- Thanks again, will have a look. One of the nice aspects of wiki is that if you don't know something there is always someone else who does.--Wolbo (talk) 14:13, 6 February 2021 (UTC)
- Wolbo, For the other part of your question, you can change the target by using the #defaultView... code in the query itself; eg this query (result) will default to showing images, while this one (result) will show the normal table view. Andrew Gray (talk) 22:30, 9 February 2021 (UTC)
- Andrew Gray, that's also useful as well as easy. Thanks.--Wolbo (talk) 17:31, 13 February 2021 (UTC)
