File Abstraction Layer

There has to be a defined way of notifying other components when a file changes. This involves moving it, deleting it, changing its contents and maybe other things.

Some questions that have to be decided upon:

1. Who triggers the notification?
   • The driver, the repository, the object itself?
2. What information should be given?
   • Which file changed, which action happened, what parts changed?
3. Should we also have a kind of pre-notification before something is changed? So the process could be interrupted before anything happened?
   • This would allow for e.g. access or license checks to forbid publishing restricted files
