<p class="MsoNormal">I was thinking that given the configuration option “use a compatible file name for writing sidecar files”, and digiKam creating files using the extensions (.on1 & .xmp) that ON1 uses, that the sidecars would be interchangeable. The internal
structure of the files even appears to be similar between what digiKam creates and ON1 creates (to an end-user, perhaps not a developer/programmer).</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Unfortunately it seems that contradictory metadata is written. As you may see in the Dropbox files jpeg metadata is overwritten by raw metadata in what are suppose to be jpeg blocks. Or, metadata is not updated without applying a very unintuitive
process. Raw photo metadata can therefore be embedded in jpeg photos.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Perhaps there could be more detailed explanation by digiKam what was meant by “Use a compatible file name….” since the way I thought it worked does not appear to be correct, or I’m not using it correctly. Or maybe ON1 has advanced the structure
of their sidecar files beyond what digiKam has programmed. </p>

<p class="MsoNormal">Ok, this is a bit complex, so I am not sure if I'll miss something.<br>
<br>
Basically you want to be able to interoperate between ON1 photo editor, and<br>
Digikam, and only using sidecar files.<br>
<br>
As far as I know, .on1 sidecars are exclusive to the ON1 photo editor, so I<br>
don't think Digikam is able to read or produce them. Apparently, .on1 files<br>
not only include metadata (like keywords and dates) but also information<br>
about the editions done on the photo. So if you edit some keywords in<br>
digikam, store them in a .xmp, and then ON1 reads only from the .on1 file,<br>
it won't see any changes.<br>
<br>
I am not sure about the correct blocks that jpg and RAW photos should or<br>
should not. I know that digikam uses a bunch of redundant keyword tags in<br>
order to be compatible with lots of other picture managers, and usually that<br>
shouldn't be a problem, so I wouldn't be worried if you see a JPG and RW2<br>
tag block (as long as there isn't contradictory information).<br>
<br>
Moreover, the information of the XMP sidecar can also be embedded in the JPG<br>
picture itself (but not the RAW, usually), so digikam and other softwares<br>
can read that information without the need of a xmp sidecar. If there is<br>
contradictory information between both, I am not sure to which one Digikam<br>
will give priority. <br>
<br>
Can you attach us an example of a picture and its sidecars (.xmp and .on1)<br>
so I can see and try for myself?<br>
<br>
