ome-ngff

Next-generation file format (NGFF) specifications for storing bioimaging data in the cloud.

Editing

Specifications are written in markdown, or technically bikeshed -- a markdown document, with special extensions understood by the bikeshed tool. The bikeshed tool is run on-commit via the spec-prod github action, generating the familiar "spec looking" ReSpec format. ReSpec is just html with a javascript ReSpec library.

Specification files end with the .bs file extension. The github action runs on commit to automatically convert to respec/html, via bikeshed.
