Program Metadata to TAG translation

(1/1)

StarGeek:
One problem that pops up sometimes is when is talking about what one program calls a metadata tag and what are the actual tags that are written.  I attempted to go though all of the metadata in my copy of Lightroom (v. 4.4) and make a translation between the two.  If anyone notices any errors or if a different version of Lightroom does things differently, let me know or post below and I'll add it in.

At some point, I'll try to do the same with some other programs I have access too. 

Let me know if anyone has any suggestions as well.

In Lightroom, ISO Country Code must consist of two or three ASCII letters, or three ASCII numerals.
The IPTC standard states that Country-PrimaryLocationCode should have a length of three.
While writing to Country-PrimaryLocationCode, ExifTool will respond with an error if the length is not three, but this limit can be overwritten with the -m optionIPTC:Country-PrimaryLocationCode

2016-01-08: First draft, info for Lightroom v. 4.4

SK:
Hi StarGeek,
First off! Great job in collating all the info!

Is there a USE CASE for groups like

* Workflow
* Models
* Artworks or ObjectsI am not familiar with LR, Is it possible to explain how these are used in LR (examples)?

There must be otherwise someone went to a lot of work for nothing.  Some (all?) of these are detailed in the IPTC-PhotoMetadata spec pdf.  For example, JobID is defined as
"Number or identifier for the purpose of improved workflow handling. This is a user created
identifier related to the job for which the item is supplied."

I can only guess at the case uses for these items as I'm simply an amateur and these seem orientated toward a professional studio or business.  For the casual user, they probably aren't of any use.

Just as an example, here's what the Workflow section in LR 4.4 looks like.  It's showing the tags I preloaded on an image in order to identify what tags are read.
