what would make you think i'm talking about protege 3? in my first mail i indeed said that this is about latest protege owl 4.1.
i'm curious why you would think that i was talking about the older one?

why is a backend not relevant? because it is easier to import/export?

you see me at a loss while reading those last two paragraphs - i dont see any difference between the two options.
yes, my file is not an OWL file - it only embeds several OWL snippets that form different ontologies when stitched together.
yes i need to seperate the OWL content from the other content (done with javacc)
i dont need to provide access to the non-OWL content - protege should only be used to edit the OWL parts of the file
and i already thought of storing the extra non-OWL content as part of the OWL passed to protege - as an annotation or something. this would then be used to reconstruct the original file structure when saving.

so what is the difference in "implementing my own file format" (first paragraph) and "encode extra non-OWL content in the OWL" - of course i have to do bothe anyways as the original format is not pure OWL to begin with but only contains it?

why do you talk about a protege 3 project/import/export plugin? aren't there protege owl 4 project/import/export plugins?

thank you for bearing with me for so long - i guess that there is some concept that i did not yet grasp to make the matter clear for me yet.
