To celebrate the 10th Anniversary of WordPress, an intermediate version 2.8.9 is released with essentially an improved class for multilingual child theme like here demonstrated. A powerful toolbox for web designer of theme.
Tests with 3.6-beta3 are good and 2.9 will be shipped with WP 3.6 RC.
This 2013 child theme uses an improved class including features to help authors during translation.
Today, by default, if you create a french post as translation from an english, all the categories are copied to the new post ready to receive the translation.
According content rules, it is sometimes possible to copy also the post-format and more. The seven options are:
Post Format: here, it is a copy but with a filter, the developer can change the rules
Post Parent: In this case, you must be sure that the current post has a parent AND the parent has his own translation because it will the ID of this translated parent that will be copied… CMS design requires 😉 !!!
Order: reserved for hierarchical post as page,
Featured image: Linked translated post will have the same featured image, (try to find the translated media).
These new options are visible since Appareance/Xili-Options/ menu, screenshot below:
