So what actually distinguishes one raster format from another? Metadata. We get philosophical about what metadata even is, examine how TIFF and Zarr each represent it, tour the various ways geospatial coordinate information is encoded across formats, ask where metadata should live, and make the case that formal, versioned conventions are what truly enable interoperability.
