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.

Map deletions?Edit

Hi - is there a reason you've just removed a thousand or more detail map (P1621) properties from items? They seem to be appropriate maps... Andrew Gray (talk) 22:36, 1 February 2017 (UTC)

@Andrew Gray: Because it's wrong and duplicate to route map (P15). If you take a look on these items, you will see, that in nearly all cases the same map was already set as P15.
I've talked to B.Zsolt who mass-introduced them today, but he didn't respond. He also set many maps, which were clearly not detail maps, but rather locator maps.--Sascha GPD (talk) 22:42, 1 February 2017 (UTC)
Ah, that makes sense! No problem. I hadn't noticed the other links on the items I checked. I'd also looked at the list of map properties on Property talk:P1621 to see if they were appropriate and "detail map" seemed the most appropriate of the ones listed... but for some reason it doesn't list "route map". Agree they fit better under P15. Andrew Gray (talk) 22:57, 1 February 2017 (UTC)
@Andrew Gray: For railway lines in Germany-Austria-Switzerland (where the most productive railway cartographers come from) we used 100 % route map. Generally I wouldn't object to change it completely to e.g. detail map, but this should not be done automatically, because there is a significant difference between detail and locator maps.--Sascha GPD (talk) 23:12, 1 February 2017 (UTC)
Map type Example
Route map / Detail map   Includes stations, rich background (some features)
Locator map   Outline of the whole region or country, uniform background (only borders)

Thank you, I understand. Sorry, I made lot of work for you... :S --B.Zsolt (talk) 00:17, 2 February 2017 (UTC)

@B.Zsolt: I respect your work, you are doing nearly everything around railway lines here.
I like the railway maps very much, but with manual work it will take years until every article has one. What do you think about speeding up the creation of railway maps? Most railway lines already have relations at OpenStreetMap (example) and it should be possible to automatically create maps from this.--Sascha GPD (talk) 10:05, 2 February 2017 (UTC)
