Is language code like en/ja/zh already defined in Mediawiki?
I tried to add Sites in following formate with addSite.php. This site do appear in Site table. However, there were nothing under site_language column. What's the correct way to insert type="language"?
<site type="mediawiki">
<globalid>enmoegirl</globalid>
<localid type="interwiki">enmoegirl</localid>
<localid type="language">en</localid>
<group>moegirlpedia</group>
<path type="link">https://en.moegirl.org/</path>
</site>
