The solution is to use sidecar XMP files. XMP is a standard for metadata
that is established by Adobe and encompass EXIF, IPTC and DublinCore in
a RDF (XML) container. It specifies writing metadata to various types of
files including JPEG, PNG and TIFF, and it has a pure XML form that can
be used for sidecar files.
Sidecar files are files that are stored next to the one they relate to.
Like img_1234.cr2 has img_1234.xmp as a sidecar file.
Sidecar files is the method chosen by various proprietary digital photo
management software including Adobe Lightroom.
