This section describes the metadata reading and writing process.
- 
          Read Exif, IPTC and XMP from the file.
        
- 
          
            Display this "raw" data in the
            Exif Window
            .
          
        
- 
          Read XMP sidecar or Geeqie private metadata file. This data will override the XMP data read from the file.
        
- 
          
            Synchronise XMP data with Exif and IPTC data. This process corresponds to the section "Reconciling metadata properties" as described in the
            XMP Specification
            .
            
- 
                detect which of Exif and Xmp.exif is newer and copy the data in the appropriate direction
              
- 
                detect which of IPTC and XMP is newer and copy the data in the appropriate direction
              
 
- 
          
            Use this "processed" data within Geeqie, with the exception of in the
            Exif Window
          
        
 
- 
          
            Metadata is written to a single file or group of files as specified in the
            Metadata
            tab of main Preferences.
          
        
- 
          Modifying the keywords, comment, orientation, etc. does not ask for confirmation, but immediately modifies the metadata in memory and adds the file to "write queue"
        
- 
          
            Writing of the queued changes is triggered either
            manually
            or as defined in
            Metadata. It is possible to review the changes and exclude selected files.
          
        
 
- 
          
            Exif and IPTC are updated from XMP (for example
            Exif.Image.Orientation
            is updated from
            Xmp.exif.orientation
            ). See
            XMP
            and
            IPTC4XMP
            specifications for the list of corresponding tags.
          
        
- 
          
            Try to write metadata in the order specified in the
            Metadata writing process
            section of Preferences.
          
        
- 
          After the first successful write attempt delete old metadata files in all possible locations.
        
 
 
      File types with allowed sidecars are listed in the
      Files Options
      tab of the main Preferences.
