- How wikidata and wiktionary databases will be synchronized?

New entity types will be created in Wikidata database, with new ids (ex. L for lexemes). A Wiktionary will have the possibility to include data from Wikidata in their pages (the complete entity or only some chosen statements, as the community decides)

The pdf mentions 4 new entity types: Lexeme, Statement, Form, Embedded (?). Curious, was the existing data model not flexible enough?

Will these new entities be restricted to the usage in a lexicographical context, i.e. Wiktionary? How will they fit into the existing data model, will there be links from existing Wikidata items to the new entities? (i.e. how will Wikidata benefit from the new data?)

- Will editing wiktionary change?

Yes, changes will happen, but we're working on making editing Wiktionary easier. Soon as we can provide some mockups, we will share them with you for collecting feedbacks.

Making contributing to Wiktionary easier will be a huge help. Right now the learning curve is extremely steep, and turning away potential contributors.

One thing to keep in mind is that Wiktionary is more than just the content in the page namespace. A big part of what you see is actually generated dynamically, for example transliteration, pronunciation and grammatical forms (conjugations, plurals etc).

I imagine in an integrated Wikidata/Wiktionary world "content" and code lives in various places, and we'll have a range of automated processes to copy things back and forth, and to automatically create new entries derived from existing ones?
