This is probably a strange one as it is not directly about ExifTool, but bare with me.
I am currently writing EXIF functionality using libexif and have done all the standard tags which I test using exifTool. I am now onto to some non standard tags that I am going to put in as maker notes.
Are there any guidelines as to how best to insert the maker notes so that exifTool will be able to process it automatically? I see a few complaints about how certain programs/camera manufacturers write their maker notes and I am trying to avoid falling into the same traps.
I recommend writing an 8-byte signature followed by a standard TIFF header and the maker notes TIFF format with offsets relative to the start of the TIFF header. ExifTool will be able to read this with the -u option if the byte order is the same as the rest of the EXIF.
Doing it this way make it relocatable, so it won't get messed up by other editors.

Grand. Will do.
