As a developer, I would like to know about the approach you take to retrieve and handle Wiktionary data for your online dictionary (pronunciation, conjugation table, etc). 

In addition, are there any of Livio projects' source code available on GitHub?

In order to retrieve pronunciation, conjugation table, flex forms and so on, we process the wiktionary using a parser that is designed for that specific wiktionary. Due to different format used by each wiktionary, we had to design one parser specific for en.wiktionary.org, another parser for fr.wiktionary.org and so on.
