Finder Tags vs Photo Keywords: IPTC, XMP and Catalog Tags
Finder tags and photo keywords are different kinds of information. A Finder tag helps organize a file in your Mac workflow. Photo keywords describe an image in a metadata system used by photography and publishing tools.
Adding a Finder tag with Little Tagger does not write that word into the photo's IPTC or XMP metadata.
The same word can live in different places
You could use "Portrait" as a Finder tag and as a photo keyword. The spelling is the same, but the storage and the apps reading it are different.
That is why a label visible in one application may not appear in another. Before choosing a tagging tool, decide where you need the information to be read.
| Term | What it refers to | A useful question |
|---|---|---|
| Finder tag | A macOS file-organization label | Can I find this file in my Mac workflow? |
| IPTC field | A defined photo-metadata property, such as Keywords or Creator | What information about the image needs to travel with it? |
| XMP | A way to represent and exchange metadata, stored in a file or a sidecar | Where is the metadata written? |
| Catalog keyword | A keyword managed by a photo application's catalog | Has the app also written it into the exported or accompanying metadata? |
The IPTC Photo Metadata Standard defines descriptive properties. Adobe's metadata overview explains XMP and sidecar storage.
IPTC and XMP are not rival sets of color tags. They describe different parts of how photo information is defined and stored.
Use Finder tags for your working context
A project can contain more than photographs. There may be a brief, a contact sheet, design exports, a licence document and an invoice.
Finder tags let you connect those different file types with names such as "Harbour Shoot", "Needs Review" or "Client Ready".
Little Tagger can apply those tags through reusable presets and workflows. The same project tag can connect a PDF brief and an image export without editing the contents of either file.
This fits the photography and design workflow: keep the project structure and add information about what the files mean to your work.
Use photo metadata for the image handoff
A recipient might need a description, creator credit or subject keywords. Put those in the metadata fields and format that their workflow expects, using an appropriate photography tool.
A Finder tag named "Licensed" is not a licence document. A tag named "Copyright" does not fill in a copyright notice. Keep the underlying records and use the right fields for the information you need to communicate.
You can use both kinds of metadata for different purposes. For example, keep "Needs Review" as an internal Finder tag while maintaining image keywords in your photo application.
A catalog does not settle what an export contains
Some applications store information in their own catalog until it is written to a file or exported with the relevant settings. Check the behavior of the application and format you actually use.
Adobe notes that Lightroom metadata must be saved to XMP for Bridge to recognize those changes in its metadata interoperability guide.
Seeing a keyword in a catalog is therefore not enough to prove that a recipient will receive it. Inspect the resulting file or sidecar.
Test a sample through your actual process
Use a disposable copy of an image and give the two metadata layers distinct names, such as "Finder Test" and "Photo Keyword Test".
Export it using your normal settings. Copy, upload or send it through the same route you use for delivery. Open the result in the receiving application and check each layer separately.
Repeat the check for the file formats you rely on. Do not assume that exporting, archiving and synchronizing all preserve the same metadata in the same way.
This is a practical test to run, not a claim that every transfer route has been verified here.
Does Little Tagger replace Bridge or Lightroom keyword tools?
No. Little Tagger works with Finder tags. Use photo-metadata tools for IPTC fields, XMP workflows and catalog keyword management.
Can I keep the same vocabulary in both places?
You can choose matching names, but that does not create synchronization. Treat the two layers separately unless your exact workflow has a verified method for connecting them.
Use the right label for the right job
For image metadata that another photography workflow must read, use the appropriate photo tool. For project, status and reference tags around files already on your Mac, Little Tagger can help you repeat the work without changing the file contents.
