Questions about metadata and databases
 
|
I want to be absolutely sure my metadata is always updated in the
image files. So, if I go to:- Settings->Configure Digikam->Metadata ... and tick all the boxes at the top ('Image Tags', 'Caption and Title', etc.) does this mean that Digikam always writes these to the image file? What are the odd looking graphics next to the text "Write this Information to the Metadata"? On my systems there's a tiny blue circle with a very thin box next to it and, underneath that an even tinier blue spot and a line next to it. Are the 'Read from Sidecar Files' and 'Write to Sidecar Files' in addition to writing to the image files or instead? I.e. do I have to leave both of these boxes unticked if I want the data in the image files? Finally, what format(s) does Digikam use to write the Metadata? At the bottom of the Metadata settings it has links which describe EXIF, IPTC and XMP but it doesn't say which ones it uses. -- Chris Green · _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

I just checked the 'time stamp' and 'caption' boxes and added a title to
one of my images. That title and time stamp appeared in the metadata under the IPTC tab. Hope that helps a little. I'm no expert. As for the odd graphics, I think it just is related to the entire check list. In other words, it's just showing that the items you check will all get written to the meta data. That dialog is asking which items you want to write to the meta data in list form. I may be wrong, but that's my opinion and I'm sticking to it. I have never used the Read/Write to/from sidecar feature, so can't help you on that one.

However the configuration options are not very clear in how they work which is really why I asked the question.

The tick boxes all look perfectly sensible but the odd things alongside "Write this information to the Metadata" worry me. Even odder, I just made the configuration settings window bigger and now there are *three* of the blue dot and white oblong graphics alongside the text! > I have never used the Read/Write to/from sidecar feature, so can't help > you on that one. > I'm not aiming to use these options either. There's a bit that worries me *there* though, in the same box as the Read/Write sidecar files tick boxes is a box saying "Update file timestamp when files are modified", does this only apply to sidecar files or does it apply to writing metadata to the image files? > > [hidden email] wrote: > > [hidden email] wrote: > >> I want to be absolutely sure my metadata is always updated in the > >> image files. > >> > >> So, if I go to:- > >> > >> Settings->Configure Digikam->Metadata > >> > >> ... and tick all the boxes at the top ('Image Tags', 'Caption and > >> Title', etc.) does this mean that Digikam always writes these to the > >> image file? > >> > >> What are the odd looking graphics next to the text "Write this > >> Information to the Metadata"?

If you look a bit below the "Write This Information to the Metadata" title, You'll see a line "Reading and Writing Metadata" with a folder icon in front of it. By analogy, the three blue dots and white bars are the icon for a list, in front of the first title... _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

However - why is there an icon for a 'list' there and the icon for a 'folder' next to the sidecar options? I don't really follow the meaning. -- Chris Green · _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
