I have to write metadatas from database to images (jpeg, tiff, bmp, psd, eps, ...).

Is there a referencial which can i use to know which metadatas i am allowed to write in which image format?

Thanks for your help

Unfortunately there is no documentation to tell you which tags you can write to which file formats (with about 4000 possible tags and 51 file formats supported by ExifTool, such a document would be prohibitively lengthy).

However, a reasonable solution may be to use XMP tags (see the
https://exiftool.org/TagNames/XMP.html" target="_blank">XMP Tags documentation).
XMP information can be written to many different file formats (JPG, TIFF, PNG,
PS, PSD, DNG...), and is becoming a popular technique for storing meta information.
