Metadata not editable for a readonly file storage
this might be correct sometimes1, but I have the usage:
readonly image-server inside TYPO3 (images are stored via FTP by graphic department), as this is a linux mount, nobody having access to the TYPO3 server can modify anything on that server.
But editors should be able to set default-values for alt, title, description, ... for the images, so they could build up a library of files with metadata.
Now they only can set these data in a usage overwriting the empty default values, which can lead to incoherent data.
as the metadata is stored in the database it is independent of writablity of the file-storage.
 possible feature:
the file-storage record may hold another flag, whether editors should be able to set metadata globaly so the file-storage is readonly else.
