[Digikam-users] Re: Digikam not writing metadata (caption/tag/rating)

[Peter Shute]

Does this mean it will begin to write the metadata immediately, but the user will not have to wait for it to finish? That sounds better than doing it all at the end, especially for laptop users who may want to shut the machine down.

I forget to said that i see some Marcel work about this subject. He
has factored a lot of code about metadata engine from digiKam. The
goal is to be able to process metadata sync in a separate process
using multi-threading, without to block GUI and using another
processor.

Not all is complete of course, but it will be available during 2.X
serie, i think...
