Thanks for your answer. It works so far, but I have some more problems/
questions.

Isn't the metadata normally written after page edit? Couldn't I achieve
that my additional data is saved then as well, because otherwise I'll
have an additional file access (by p_set_metadata) which I'd like to
avoid (cause of the performance).

Second problem is that I use the 'IO_WIKIPAGE_WRITE' event to save my
metadata (if it has changed). But this event is only triggered when
there have been changes to the wiki/ page text. In case that only my
metadata has been changed, it won't be saved. Any solution, other than
making any pseudo editing?
