Program Metadata to TAG translation

[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.

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

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

Is there a USE CASE for groups like

• Workflow
• Models
• Artworks or Objects

I am not familiar with LR, Is it possible to explain how these are used in LR (examples)?

Is there a USE CASE for groups like

• Workflow
• Models
• Artworks or Objects

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.

It's not pretty, but here is the data for Flickr

• ¹ No field name shown, sometimes there is an icon
• ² GPS map locations are shown based upon GPS privacy settings at time of upload

   
• If IPTC:Keywords and XMP-dc:Subject do not exist, then Tags is populated with all of the listed combined tags.
• If the "Show Exif" link is clicked, all tags extracted by Exiftool are shown, as Flickr uses Exiftool to extract metadata.

I've been working on Videos in Lightroom and i wanted to add that they have a Video Metadata section, weird as it is since you can't edit tags on Videos in LR. Anyways it starts off with information i gathers from a scan of the video, stuff like;
Duration
Trimmed Duration
Video Frame Rate
Video Alpha Mode
Video Dimentions
Audio Channel Type
Audio Sample Rate
Audio Sample Type

It then proceeds with metadata of the video file, it seems that this information was mostly gathered from this webpage;
https://community.adobe.com/t5/lightroom-classic-discussions/lr-4-changes-to-photo-get-metadata/m-p/4066165

Just after some basic tests it seems most of those are coming from the;
XMP xmpDM Tags
such as;
Director of Photography -> [XMP-xmpDM] DirectorPhotography
Day of Shoot -> [XMP-xmpDM] ShotDay

But also some of my entries are coming from [ItemList] which i thought was more Quicktime tags. Anyways i thought i would add this to the knowledge of LightRoom. I'll try experimenting a bit more to see if i can track down some more of these tags.

I went through the tags today and indeed they are the XMP xmpDM Tags
a bit more can be found about Adobe use of them here;
https://developer.adobe.com/xmp/docs/XMPNamespaces/xmpDM/

So these are the values i found, they may contain errors and not complete so use at your own risk;
