Media import - matching options and preferred labels
I have some questions on the media import.
1.) Is matching only possible via identifier?
In Providence and in the caUtils script it seems only to be possible via identifier. The identifiers are auto-generated in our setup and we would ideally need matching on the preferred label or a custom field.
2.) Is it possible to control the setting of the preferred label for the object?
When importing an image with name 123.jpg, the preferred label of the object will be set to 123.jpg. Can this be configured to be set to 123?
3.) Is it possible to control the setting of the preferred label for the media represenation?
When importing an image with name 123.jpg, the preferred label of the media representation will be set to "[BLANK]". Can this be set to a different value?
4.) What exactly is the difference between type "back" and "front" for media representations?
I could not find anything in the Wiki on this topic. If there is a Wiki page, please point me to it.
