Fotoidy

Fotoidy is a term used in discussions of digital photography to describe an open metadata framework and image container intended to improve attribution, provenance, and long-term accessibility of photographic works. The name combines “photo” with “idy,” a shorthand for identity, highlighting its emphasis on identity-related data accompanying an image.

Overview: Fotoidy specifies a modular container that pairs image data with structured metadata. The metadata model supports persistent identifiers, provenance chains (photographer, date, location, processing history), licensing terms, rights management, and subject or scene tagging. The framework aims for interoperability by adopting widely supported formats such as JSON-LD for metadata and allows both embedded metadata and external sidecar files.

Technical characteristics: It is designed as an extensible schema with optional features such as cryptographic hashes for integrity, edit versioning, and mechanisms to verify authenticity.

History and development: The concept emerged in digital heritage circles in the early 2020s in response to attribution and provenance concerns. A collaborative draft specification and reference implementations have been released by a loose consortium, with gradual adoption among archives, museums, and large platforms.

Impact and reception: Proponents argue it improves attribution, searchability, and licensing clarity; critics raise privacy concerns and the potential for metadata to be misused for surveillance, especially when location data are included.
