How MetadataAI™ Reads and Writes All Metadata Types — Seamlessly

MetadataAI Doesn’t Just Read Your Metadata — It Understands It

In last week’s kickoff to Series A, we broke down the differences between Exif, IPTC, and XMP metadata — and why they matter. Today, we’re going deeper, tackling the technical heart of MetadataAI™: 

How it reads, writes, and synchronizes metadata across all three standards — safely, reliably, and intelligently.

For photographers, editors, archivists, and developers alike, this is one of the most important (and underappreciated) challenges in metadata management. It’s one thing to read metadata — most tools can do that. But it’s another thing entirely to write metadata safely, and to do so in a way that works across all major systems and standards.

The Problem: Metadata Is a Mess

Let’s start with the real-world situation:

  • You tag your photos in Lightroom, Capture One or PhotoMechanic…
  • Then export them with “metadata preserved”…
  • However, later you find that only the XMP fields were updated, while the IPTC fields are empty, and Exif still displays your old description.
  • You upload to a stock site, and it pulls… the wrong caption. Or none at all.

Sound familiar?

This happens because different programs and systems prioritize different metadata fields — and most tools only update one standard at a time.

The MetadataAI™ Solution: Intelligent Multi-Standard Syncing

MetadataAI doesn’t treat Exif, IPTC, and XMP as separate silos. It treats them as an interdependent ecosystem — and updates each accordingly.

Here’s what that means:

It Reads All Metadata

  • Exif: Camera info, timestamps, GPS, image dimensions, etc.
  • IPTC: Captions, credits, copyright, keywords, usage rights
  • XMP: Extended IPTC, Adobe fields, AI-generated tags, custom namespaces
You see exactly what’s in each field — whether it was added by a camera, a human editor, or an AI model — and can compare and reconcile differences directly in the app. 

It Writes Metadata the Right Way

When you edit or generate metadata with MetadataAI, it doesn’t blindly overwrite a single field. It:

  • Updates multiple corresponding fields when appropriate (e.g. XMP:Description, IPTC:Caption, Exif:ImageDescription)
  • Preserves existing metadata when not being updated
  • Respects embedded vs. sidecar workflows, depending on file type
  • Handles UTF-8 encoding properly so special characters won’t break on import

Use Case Example: Editorial Workflow for a Wire Service

Let’s say a photo editor at a newswire needs to prepare 200 images for same-day distribution. With just a few metadata configurations in place, any output metadata fields are customizable:

  1. The editor reviews and tweaks the caption.
  2. When saved, MetadataAI automatically writes:
    • IPTC:Caption-Abstract
    • XMP-dc:Description
    • Exif:ImageDescription These fields are synchronized to match — ensuring compatibility across legacy CMS systems, DAMs, and social platforms.
  3. The wire partner downloads the image with all new associated metadata and loads it into their own system — which, without asking, reads IPTC:Caption. It’s there, intact, and matches the AI caption the editor approved.

The AI captioning model in MetadataAI generates a caption like:

“Protesters gather outside city hall following a council vote on housing reform.”

That’s metadata trust in action.


Under the Hood: How MetadataAI Uses ExifTool and Composite Tags

At the engine level, MetadataAI leverages ExifTool — but it doesn’t stop there. MetadataAI also uses ExifTool composite tags. These are smart “meta-tags” that automatically handle cross-field logic for you.

Example:

  • When you write to MWG:Description, ExifTool understands how to write to all the relevant fields across Exif, IPTC, and XMP standards — according to best practices outlined by the Metadata Working Group (MWG).

This ensures:

  • Field values are aligned and redundant in a good way (for system compatibility)
  • Files remain standards-compliant for archiving, licensing, and publishing
  • There’s no “metadata drift” between different applications

Why This Matters for Your Workflow

Whether you’re:

  • A photojournalist delivering images under deadline
  • A photo library maintaining legacy metadata integrity
  • A digital asset manager creating AI workflows for images
  • A developer building automations for tagging

…you need a tool that understands and protects the metadata triangle: Exif, IPTC, and XMP. 

Tools that ignore one side of the triangle lead to:

  • Broken search indexing
  • Lost copyright or creator info
  • Errors in image licensing or syndication
  • Lost time

MetadataAI prevents those problems with metadata you can trust — across platforms, ecosystems, and stakeholders.
