I was testing metadata driven view and it seems that it is not meant for editing files. Am I correct? Although in this tip and comments I get impression that editing might be ok same way it is in GIT-branches normally. Documentation does not say anything about editing
Well, you can edit files and make changes, but a view branch is not your master branch. If you add a new file, or edit an existing file in a view branch, nothing will update the master branch to add that new file to it.
When you switch back to the master branch, or check out a new view branch, your changes remain in the view branch. They're not lost, because each view branch has its own name, and you can check out the branch again.
Although re-running
git annex viewwill regenerate the view branch, so losing your changes. (The old version of the branch will still be preserved in git's reflog for a while.)I'd say they're mostly for viewing, not editing, but there might be ways to use them for editing given these constraints.
