Uwe Posted February 4 Report Share Posted February 4 Hello, in the preferences it is set that for RAW files tags are written to the XMP sidecar file. So far so good. But should/must this also apply to the DateTimeOriginal tag, for example? If you have to adjust the timestamp of the RAW file after the XMP sidecar file exists, then Daminion only changes the XMP file. This therefore leads to a difference between the DateTimeOriginal tag in the RAW file and the XMP file! How are other systems/apps/DAM supposed to know which timestamp is correct - DateTimeOriginal of the RAW file or the XMP file? Is the generated difference an error in Daminion? In comparison, IMatch, for example, changes the DateTimeOriginal tag in both the RAW file and the XMP file in the above-mentioned case, but does not write any other metadata to the RAW file, as Daminion does.

Daria Kotilainen Posted February 4 Report Share Posted February 4 Hi Uwe, If you set the tool to write tags in XMP, we follow the settings and modify the XMP only. If you want to modify the RAW file, please change the settings to writee tags to RAW file. Unfortunately, it is either of two. We cannot write both to RAW and XMP. Kind regards, Daria Quote Link to comment Share on other sites More sharing options...
Uwe Posted February 5 Author Report Share Posted February 5 HI, in another forum I asked the same question and got this answer: "There should never be two sources of truth for metadata. Many tags in XMP, EXIF, GPS IPTC are linked and mirror each other. Many "entry-level" applications out there don't bother to synchronize properly, which always causes problems." Of course, Daminion is not an entry-level app. So my question is along the following lines: as a Daminion user, do I have to live with ‘two truths’ regarding the time stamps and how can users to whom I have to send the original photos find out the truth? The way I interpret the XMP sidecar file, it should keep the RAW file as ‘original’, which is not possible with the timestamp. I have only briefly tested (combination RAW+XMP) which timestamp is used for sorting by date taken. I hope I haven't made a mistake! XnView: RAW - Exif:DateTimeOriginal Imatch: RAW - Exif:DatetimeOriginal DxO Photolab: XMP:DateTimeOriginal LuminarNeo: RAW - Exif:DateTimeOriginal W11 Explorer, ignores XMP: RAW - Exif:DateTimeOriginal W11 Photo Viewer: RAW - Exif:DateTimeOriginal I am interested in how other Daminion users deal with this issue. I am looking forward to it and best regards, Uwe Quote Link to comment Share on other sites More sharing options...
