What is the meaning of the dot (.) in Japanese dictionaries?
This is the first dictionary I've seen use this particular notation, but it
appears to be a delimiter between the part of the word composed by the kanji
reading and the [okurigana](https://en.wikipedia.org/wiki/Okurigana).

See how for both of the words on the example page you gave, the dot appears
immediately before the okurigana begin.

> 表{あらわ}すー＞あらわ.す
>
> 表{あらわ}れるー＞あらわ.れる

Searching for another word,
[焼ける](http://tangorin.com/general/%E7%84%BC%E3%81%91%E3%82%8B), gives me the
same results.

> 焼{や}ける -> や.ける
