[Digikam-users] database on laptop and server/NAS

Gilles, Ben,

thanks for the quick answers! Let me summarize, what I understood, to make sure I got everything:

1. There seems to be no way currently to move additional meta data from one DB into another with methods provided out of digikam.

2. The (external) srcipt Ben proposes, needs a unique key to identify the pictures for synchronization between the two instances of digikam. He mentioned either a unique filename or a hash (not sure, probably stored within the DB and not visible to he normal user?)

3. Gilles mentioned a new DLNA export, that solves parts of my problem, showing (parts of) the collection on a TV or the iPad. What is a very promising outlook.

Unfortunately I am not able to write the script, Ben proposes, and the DNLA streaming does not help me to import the parts of the collection, I am working with, when on the road, coming back home. Remember, because of the screen size of the laptop, I would appreciate still being able to do some image fine tuning (plus geo tagging and so on) on a desktop.

Just an end user's thought: Would it be possible to expand the "Export/Import to/form another computer" function by a checkbox "include meta data", that writes/reads an "album side cart" for digikam-to-digikam transfer?
