Hi,

I think I found a good way how this can beed done. I'm not going to lock
something, but make it as 'someone is editing this'. This way it it
possible that two people edit something simultaneous.
The mark and the original content of the resource is stored in datatree.
Before it is saved, the original data from datatree are compared with
the target source. When the two differs it created a patch from the
original data in datatree and the data which the user submitted (using
Text_Diff) and try to patch the target source.

The problem I have, is that I have no php code that can apply a patch.
Anyone know if there is code that does this?

by, Martin
