I would like that too, but that can get weird in a hurry. Mainly because various programs don't call fields by the exact same name; i.e. what is "Byline title" in XNViewMP, it's "Author's Title" in IrfanView, it's "Job Title" in Lightroom and ACDSee, and "Creator's Job Title" in PhotoMechanic; and it's missing entirely from MC. One looks up and down 5 times for each program to see if the data doesn't pop up under some other name, and then do the whole exercise again some 70 times for all the other fields and... I tried. I felt like throwing things at the monitor after 30 minutes. I've seen some comparisons online but they were from 2007 or something, not actual anymore.
Anyways. There are resources out there. I don't know if this helps Matt & team, to feed the entire IPTC standard into some implementation/validation/automation but the latest specs are here in JSON and YAML formats. Main page here. I totally get it that very few people will need exotic stuff like "ISO Country code" or "Featured Org. Code" fields, although supporting the whole standard may be an extra selling point for MC; if you can use the data I linked to bulk-implement these (can you tell I'm not a coder? :) ) - awesome; if not, any efforts to add any more useful metadata are greatly appreciated.
Of much fun is THIS image they provide, that actually has all the IPTC fields populated (Core and Extensions) and can help see how thorough the IPTC metadata implementation is in your fav viewer/DAM/etc. Lightroom and PhotoMechanic dwarf everybody regarding fields recognized.
JimH:
We will continue to work on this. It might help if you can suggest a few IPTC tags we should read.
It's amusing to be advised to support "standards". We invented our image tagging because we could find no standards when we began supporting images. That was 2007 or a little earlier, around the same time that Lightroom appeared.
Correction. Our image support dates back at least to 2004 with MC11.

Perhaps JRiver could start off with a more modest goal: produce and maintain a table of all its built-in image tags, showing the standard metadata mappings (from XMP, IPTC, Exif, ...) performed by MC (the relationship to tags in popular image processing programs would be an added bonus, but I would not expect it from JRiver). A good start would be a clear, updated tabular version of the information in the Wiki page Photo Tagging (https://wiki.jriver.com/index.php/Photo_Tagging). For dates, a table could indicate how MC internally maps imported OS dates upon a file read, and indicate any MC or OS dates which change after an image file save.
For an analogous example, here is how the program Mp3tag documents its mapping of multiple Audio metadata formats:
https://docs.mp3tag.de/mapping/
https://docs.mp3tag.de/mapping-table/
6/11/2023 Updated for clarity.
Matt:
We're writing a new EXIF framework now. The current one is not able to write tags if they're not there. It will be a few weeks but expect full read and write support. Thanks again for the help.

This should start to be available in a few days.
