Does anyone have quality information about a general publisher/developer working relation. In special i would need some links, documents or information from people who have real knowledge of those things (i.e. product owner, code owner, selling income/loss sharing between the two and so on) The information should fit a game engine product description as much as possible. Thanks!

There is no such thing as a "general publisher/developer relationship". Every developer is different, every product is different, every deal is different and hence every relationship is different. There are many different forms of deal that publishers/developers can enter into (far too many to list here).

Developers make games, publishers publish them. They share the revenue is accordance with the contract they negotiated. If you want more specific information you need to ask more specific questions.

For more general information read the articles here http://www.obscure.co.uk/industry.shtml

yes, i understand every deal with its own rules
the link was useful, thank u!
