Converting a Cube to XMP: A Step-by-Step Guide

• Cause: The CUBE was a 1D LUT (only brightness, no color) or an identity LUT.
• Fix: Test the CUBE in DaVinci Resolve or Lattice to verify it actually contains a color transformation.

• Construct XML with Adobe’s namespace.
• Insert base64 blob into <crs:LUT1>.

Convert Cube to XMP: A Practical Guide

Introduction

In modern data and digital asset management workflows, you may encounter a niche but important requirement: converting a Cube (e.g., OLAP cube schema, data cube, or semantic cube definition) into XMP (Extensible Metadata Platform) format. While these two structures serve different primary purposes — cubes for analytical data modeling, XMP for metadata embedding in media/files — the conversion can be useful for: Converting a Cube to XMP: A Step-by-Step Guide

2. Input Format: .cube

• Standard format for 3D LUTs.
• Defines a 3D grid of RGB output values.
• Typically 17x17x17, 33x33x33, or 65x65x65.
• Simple text format with header lines:

  TITLE "My LUT"
  LUT_3D_SIZE 33
  DOMAIN_MIN 0.0 0.0 0.0
  DOMAIN_MAX 1.0 1.0 1.0

XMP (Extensible Metadata Platform): An ISO standard (ISO 16684-1:2019) metadata framework that allows for the embedding and exchange of metadata across different systems and applications. XMP is widely used in various industries, including photography, design, and document management, to describe and manage metadata associated with digital assets.
