 # What is a FAIR-IO
-A FAIR-IO bundle combines the necessary acquisition and provenance metadata together with multi-resolution, chunked binary data in a single cloud-compatible format for simplified sharing and re-use.
+A FAIR-IO (FAIR Image Object) bundle combines acquisition and provenance metadata together with multi-resolution, chunked binary pixel data in a single cloud-compatible format for simplified sharing and re-use. As such, FAIR-IO implements
+a FAIR Digital Object (FDO, DOI:10.5281/zenodo.7824714) as illustrated below.
