OpenRaster (.ora) is an multi-layer interchange format for opensource graphics applications. It is the native file format for Mypaint and is well supported by both Krita and the gimp. It is basically a zip file containing an xml document and png images. Dolphin has a preview plugin for this format. It would be nice if this was supported in Digikam in the same way that gimp xcf is supported in digikam (and be a lot easier to support). Krita kra is another zip,xml based format that would be nice to have some level of support for. Neither of these are high priority but they should be in the bug tracker for sake of completeness Reproducible: Always
ok I may have been a little hasty here, It seems that I can get these file types to work up to the point of displaying thumbnails and being able to tag them etc -- editing is not so critical writing out sidecar files would be nice though - what might be better long term may be to embed the sidecar file inside the the zip archive.
more research http://en.wikipedia.org/wiki/OpenRaster it seems that openraster can store xmp and exif data in the file itself. sounds like I should be handing this bug report down to the libraries that digikam uses to handle this, which are they again?
>sounds like I should be handing this bug report down to the libraries that digikam uses to handle this, which are they again? Yes, Exiv2 shared library (http://www.exiv2.org) Note : Thumbnails are managed by KDE kioslave. So it's KDELibs stuff, especially with non native file format supported by digiKam Gilles Caulier
What's the status about .ora and .kri thumbnailer? Is any Kioslave developer taking this suggestion into account from 2012? GNome has yet that thumbnailer ... http://www.davidrevoy.com/article/194/gnome-files-thumnailer-for-ora-and-kra-images.html Will KDE user have it too soon? Thank you
I fork to KDELibs this entry to know the status of .ora and .kra support through kimgio. Gilles Caulier
Thank you Gilles ;)
The OpenRaster specification was expanded so complaint versions should include both a thumbnail size preview /Thumbnails/thumbnail.png as well as a full sized preview mergedimage.png http://www.freedesktop.org/wiki/Specifications/OpenRaster/Draft/FileLayout/ the change was deliberately intended to viewer support easier.
Good news!
Note. Ora files are just displayed well in digiKam 6.0.0 with KImageformats 5.42. Kra files are not yet recognized. Gilles Caulier
Do .kra files show when Krita is actually installed? I had the impression Krita installs a thumbnailer.
As i remember, I tested with and without Krita installed. .ora work in both cases. .kra do not work at all. I don't check if the Krita thumbnailers package is installed. I will check it. But in all cases, i expect to see the .kra thumbnails working without Krita installed on the system, as for .ora files. Gilles Caulier
I do not see any Krita thumbnailer .so installed in Krita package. I take a look in source code, some thumbnailer classes exits but not shared. Perhaps it's present in Calligra ? Gilles Caulier

Raphael has report 2 other files which are now closed in digiKam side with 7.0.0 release: bug #372568 bug #412374 Gilles Caulier
Digikam git can't export to .ora format. This essential function is not available in Digikam editor. Conditions: Digikam git Arch Linux system kimageformats5 5.112.0-1 (kf5) qt5-imageformats 5.15.11+kde+r12-1
The ORA format can only be read with the KImageFormats plugins. A write function is not implemented. Submit a wish as bug report to the KimageFormats plugins for writing support of the ORA format. Maik
Also note that the ORA format is not supported by Exiv2 or ExifTool (ExifTool only recognizes that it is a ZIP container). Maik
