As an editor on [[ https://wikisource.org | multilingual Wikisource ]] I want to have language links to the language-specific Wikisource editions show up in the right-hand sidebar of a page where available on Wikidata on order to make that content discoverable.
**Problem:**
Wikisource has a special setup. There are language specific versions at https://de.wikisource.org etc and then one multilingual one at https://wikisource.org. We did work to make it possible to add sitelinks for multilingual Wikisource on Wikidata. But the sitelinks on Wikidata are not yet used to generate language links in the sidebar of a multilingual Wikisource page.
**Example:**
* https://wikisource.org/wiki/Wikisource:News has no sitelinks to various language-specific Wikisource editions even though the Wikidata Item at https://www.wikidata.org/wiki/Q79790 has them.
**Screenshots/mockups:**
On Wikidata:
{F34476915}
{F34476913}
On multilingual Wikisource:
{F34476917}
**BDD**
GIVEN a Wikidata Item with sitelinks to multilingual Wikisource and at least one language-specific Wikisource edition
WHEN viewing the multilingual Wikisource page
THEN the language link to the language-specific Wikisource edition is shown in the sidebar of the page on multilingual Wikisource
**Acceptance criteria:**
* Language links to language-specific Wikisource versions are shown in the sidebar of multilingual Wikisource where available in the corresponding Wikidata Item
**Original report:**
It seems that no one asked for interlanguage links in T138332, even though it’s one of the main reasons to have Wikidata connection. Please display interlanguage links based on Wikisource sitelinks on multilingual Wikisource (i.e. the English interlanguage link on multilingual Wikisource should point to `enwikisource`, the German interlanguage link on multilingual Wikisource should point to `dewikisource`, and so on).
