I shall use JRiver to stream / render media content (photo / video) to the wide screen TV. For managing the media files – for example, tagging keywords, updating the EXIF, IPTC, XMP meta data embedded within the photo JPG files, I want to keep on using my existing Digital Asset Management DAM software. I have no doubt that JRiver can pick up the meta data upon importing the photo JPG files and capture their meta data into its media library. If I change the meta data in these imported photo JPG files using my DAM software outside JRiver, how can I trigger JRiver to update its media library to reflect the meta data changes of these imported photo JPG files?? I have over 20,000 photo JPG files. Will JRiver need to scan all of them to identify which one has been changed?? My photo JPG files are kept in multiple folders. Can I instruct JRiver just to scan one of the folder instead of all 20,000 photo JPG files??
