ruby-data-uri 0.1.0-2 (amd64 binary) in ubuntu focal

 Data URIs allow resources to be embedded inside a URI. The URI::Data class
 provides support for parsing these URIs using the normal URI.parse method.
 .
 This was written to support embedding binary data inside JSON messages in a
 relatively reasonable way. If you find some other use for it, please drop a
 line to the upstream.
