What it is
Darkbox: the homepage
Darkbox is an open specification for project files designed to keep people's work understandable and recoverable beyond the lifetime of the program that created it. Each file is a ZIP archive containing SQLite databases, a JSON manifest and documentation needed to interpret its contents.
The format bundles documentation for the container, SQLite file format and application data travels with every project. It defines common packaging and metadata, while each application keeps its own filename extension and describes its schemas, resources, versions and migrations in its own profile included in the archive.
The accompanying Rust CLI performs offline verification and inspection without requiring network connection or the original application. It bundles SQLite and references for its supported versions, and provides JSON reports for scripts and pipelines.
