OpenRaster is an exchange format between layered photo editing programs. It is supported by GIMP, Krita, imagemagick, Scribus, and others. A GIMP project can be exported as OpenRaster, and then opened in Krita for example.
testdata/sample.ora was generated in GIMP, and is the usual cat image, but with a reflection.
Expanding the OpenRaster as a zip reveals a transparent directory structure.
Detection
OpenRaster is zip wrapped with unencrypted mimetype file containing "image/openraster".
