I am interested in a correct way to show search engine that the link is a translation of some content to another language.
For example: you have some article written in German. So this is original post, but this post was also translated into English, Japanese and French. How should I semantically format these links?
Looking at wikipedia, I see that they are doing it with
<a href="..." title="..." lang="fr" hreflang="fr">Français</a>. Also I assume that Wiki is doing this in the right way, but I want to know for sure is this the correct way? Also I do not see there how should I specify that German is the original article and everything else is a translation.
