If you want metadata to be preserved - put it in a documented metadata format: EXIF (but only documented tags), IPTC, or XMP.
Photoshop throws away undocumented tags for a reason: they cause big problems when they get out of sync with the image data. (think: smoking printer -- yeah, it really happened)

Subject: Writing custom TIFF tags to Photoshop saving TIFFs(withPhotoshop) Re: [Tiff]
I had similar needs, and have written an enhancement for the tiffset utility that allows you to do this. I have uploaded the corresponding patch to bugzilla. You should be able to download it from there if desired and rebuild tiffset. Hopefully this will soon be included in a standard logTIFF release.
Subject: [Tiff] Writing custom TIFF tags to Photoshop saving TIFFs (withPhotoshop)
I'm thinking of introducing custom TIFF tags into my TIFF images produced within Photoshop, and I'd like Photoshop to save the TIFF images *with* the custom TIFF tags.
Would someone please give me pointers (i.e. general direction) on how I would go about doing this?
