<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">As reported in my previous messages (Digikam-users Digest, Vol 186, Issues 10 & 13), my problem was that "Reread Metadata from File" did not appear to be working when I attempted to synchronize keyword tags with a foreign program. In my case the foreign program is F-Stop Gallery, an Android app running on a Chromebook, with digiKam 7.1.0 also running on the Chromebook in Linux. The tags were actually being read successfully from F-Stop and were visible in the digiKam Tag Manager but crucially they were not visible under Captions > Tags in the Right Sidebar (which I wrongly referred to as the Tag Manager in my last message). I am using Captions > Tags in the Right Sidebar to add and delete tags from individual images.</div><div class="gmail_default" style="font-family:verdana,sans-serif"></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">After much trial and error, I have now established reliable keyword tag synchronization between F-Stop and digiKam. F-Stop uses Xmp.dc.subject for keyword tags and everything works fine when I move this field to the top of the list of metadata namespaces in Settings> Metadata> Advanced> Tags. There is a note in Settings> Metadata> Advanced> Tags saying that "Sequence is important when reading metadata" but the documentation doesn't provide any tips to help find the right order.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Based on my experience, "Reread Metadata from File" works reliably when the metadata namespace used by the foreign program is moved to the top of the list
(in my example Xmp.dc.subject). Of course the field to be moved would depend on the foreign program. My hypothesis is that in order to synchronize keyword tags effectively with Lightroom, for example, the field Xmp.lr.hierarchicalSubject should be moved to the top of the list.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Can anyone confirm whether this hypothesis is reasonable or alternatively provide any other guidance on the principles behind sequencing the fields in Settings> Metadata> Advanced> Tags? Keyword tags are very widely used so if any guidance can be provided it would be helpful to many users.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">regards,</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Fred</div></div>
