Tried Docker version,

$ docker run -i -t --rm seebi/rdf.sh desc foaf:Person
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "desc": executable file not found in $PATH: unknown.

Please try

docker run -i -t --rm seebi/rdf.sh rdf desc foaf:Person

this should work
