Hey folks :)
When using data from Wikidata on Wikipedia and other sister projects there is currently a limitation in place which hinders some use cases. Data can only be accessed from the corresponding item. So for example the article about Berlin can only get data from the item about Berlin but not from the item about Germany. This had technical reasons. On Monday we will remove this limitation on the first wikis. This will be Dutch Wikipedia and French Wikisource. (More will follow over the next weeks. We hope to have it rolled out nearly everywhere by the end of June.) We invite you to play around with this new feature if you are one of the people who have been waiting for this for a long time. If you have technical issues/questions with this you can come to https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team
A note of caution: Please be careful with how many items you use for a single page. If it is too many page loading might get slow. We will have to see how the feature behaves in production to see where we need to tweak and how.
How to use it once it is enabled: * Parser function: {{#property:capital|from=Q183}} to get the capital from the item about Germany * Lua: see https://www.mediawiki.org/wiki/Extension:Wikibase_Client/Lua
Cheers Lydia, who is very happy this is finally getting out
