How to create a quality example?

If you have encountered an issue and you would like to make that observation public to other participants then please have a look at the help page on "How to create a quality example".

Localization and multilingual content

This wiki uses "French" as its global content language (site language) for the purpose of testing different solutions in connection with localization and multilingual content aspects.

If you are adding examples where numbers contain . as decimal yet French expects , as separator, the simple solution is to let the individual page know that you are writing in English (or any other language, see the Berlin page for more information on how to change the page content language).

Sample pages

Athens, Berlin, Capelle aan den IJssel, London, Lorem ipsum, Lorem ipsum Export, Recurring events, Subobject, Transclusion/Embedded demonstrate the usage of in-text annotations for most user-defined properties.
John Doe shows to usage of imported vocabularies.
Export collects pages that can be exported via Special:Export
