then you are not going to be stuck to standards that are today supported by so many tools and standard libraries. It's like wanting your PNG's alpha channel saved seperately in XML - just not going to happen. not as a standard at least. > These image files are precious, and I don't want even the slightest risk of > buggy software ruining them, or one software making changes to them that well, then use software with a good track record. > them the original file, not one with my (potentially) personal tags. what kind of personal tags? if you tag your home-made porn and then share it, the tags are the least of your worries, and if you tag your in-laws with derogatory remarks, well then... :-) what in your tags can be more personal than the image (which is worth a thousand tags)? > My hope was that all metadata will be kept in a one simple file, holding a > map from an image checksum to its metadata. By using image checksums (e.g., not workable. my images are 3meg JPEGs to 12 meg raw files to 30-50meg PSD files. I can't do an MD5 each time I want to look up the metadata, that would be insane. it's cool to keep the md5 if the file moves or changes names, but not for full time. > md5) and not filenames, I will be able to move images on the filesystems or > between machines without losing track of the metadata I recorded for them. unless you hide it in a file "fork" like on a mac or in NT, your only way of copying a file with its metadata is a directory per image (with the metadata, thumbnail and whatnot) or in-line metadata. I don't see any problems with that. > In my (pipe) dreams, there will be a standard metadata-map format (of the > type I described above), that all applications will know how to parse and/or > edit. well, that's one of the many lovely features shared in the Adobe creative suite (and it can be kept in their mySQL backend "VersionCue"), but I'll be amazed to see all gnome, kde and other apps accept such a standard as well -- Are you talking to me?
