The original of that documentation file
is maintained on the
OpenTravelData (OPTD) project,
within the ci-scripts
directory.
OPTD produces (at least) two kinds of (mainly CSV) data files:
opentraveldata
folder,opentraveldata/optd_por_public_all.csv
opentraveldata/optd_airlines.csv
The deployment/release itself is managed through Travis CI,
specified in the .travis.yml
YAML file.
