About:
Exempi is a C++ library that provides a robust API for parsing, editing, and saving XMP (Extensible Metadata Platform) metadata embedded within digital media files. It serves as a powerful backend for applications needing to manage rich metadata without relying on Adobe's proprietary SDK. Its main value proposition is offering a stable, open-source solution for complex metadata workflows across various file formats.

Key Features:

Support for reading and writing XMP packets
Handles multiple file formats including JPEG, TIFF, and PNG
Provides a C++ API for integration into applications
Implements the full XMP 2.1 specification

Use Cases:

Embedding copyright and licensing info into images
Automating metadata extraction for digital asset management systems
Developing custom image processing tools that preserve metadata

Alternatives:

exiv2 – Exiv2 is a more general-purpose metadata library that supports Exif, IPTC, and XMP, whereas Exempi focuses specifically on robust XMP implementation.
