zip is fine and is probably slightly better for cross-platform support 
so I'd just stick with that.

PDF is listed (at the top) and svg is also listed further down. 
Latex/Tex would obviously definitely count as open so no problems there. 
Intaglio looks to be a mac osx drawing programme. As it looks to be 
proprietary I suggest not using its own format but exporting whatever 
material you made in it to an open format (png/svg/...).

In terms of compressing them you really just want to compress them 
together into a single bundle using 'zip'.
