Overview

That repository features scripts to check the quality of the data files produced by the Open Travel Data (OPTD) project.

Though it is not well maintained, that project should produce a Quality Assurance (QA) dashboard, much like Geonames' one. See the Geonames use case on the Data Quality reference page for more details.

For now, the results of the data quality checks are available on the Transport Search data QA page. For instance, for the 2 June 2021 snapshots:

The corresponding checkers are scripts, maintained in a dedicated checkers/ directory of this repository. Most of them are written in Python, but any other programmation language may be used.

And, hopefully, the QA dashboard will be powered by container images generated thanks to that repository as well.

Travis CI builds are partially covering the tests in https://travis-ci.com/opentraveldata/quality-assurance

Most of the scripts generate CSV data files, which can then be uploaded in databases (classical relational database systems (RDBMS) such as PostgreSQL or ElasticSearch (ES)), or served through standard Web applications. For historical reasons, some scripts may still generate JSON structures on the standard output. In the future, JSON should be used only for metadata, not for the data itself.

The CSV reports are published (thanks to Travis CI) to an OPTD-operated ElasticSearch (ES) cluster. The full details on how to setup that ES cluster, on Proxmox LXC containers, are given in a dedicated elasticsearch tutorial.

For convenience, most of the ES examples are demonstrated both on a local single-node installation (e.g., on a laptop) and on on the above-mentioned cluster.

Quick starter

Through a pre-built Docker image

  • Retrieve the Docker image:
$ docker pull infrahelpers/optd-qa:latest
  • Launch the Docker-powered scripts:
$ docker run --rm -it infrahelpers/optd-qa:latest bash
[build@8ce25cc20a10 opentraveldata-qa (master)] make checkers
[build@8ce25cc20a10 opentraveldata-qa (master)] exit

Installation

With a manually built Docker image

Through a local cloned Git repository (without Docker)

$ mkdir -p ~/dev/geo
$ git clone https://github.com/opentraveldata/quality-assurance.git ~/dev/geo/opentraveldata-qa
$ pushd ~/dev/geo/opentraveldata-qa
$ ./mkLocalDir.sh
$ popd

On the local environment (without Docker)

As detailed in the online guide on how to set up a Python virtual environment, Pyenv and pipenv should be installed, and Python 3.9 installed thanks to Pyenv. Then all the Python scripts will be run thanks to pipenv.

Pyenv and pipenv

  • As a summary of what has been detailed in above-mentioned how-to (and which needs only to be done once and for all):
$ if [ ! -d ${HOME}/.pyenv ]; then pushd ${HOME} && git clone https://github.com/pyenv/pyenv.git $HOME/.pyenv && popd; else pushd ${HOME}/.pyenv && git pull && popd; fi
$ export PYENV_ROOT="${HOME}/.pyenv"; export PATH="${PYENV_ROOT}/.pyenv/shims:${PATH}"; if command -v pyenv 1>/dev/null 2>&1; then eval "$(pyenv init -)"; fi
$ pyenv install 3.9.1 && pyenv global 3.9.1 && pip install -U pip pipenv && pyenv global system
$ pushd ~/dev/geo/opentraveldata-qa
$ pipenv install
$ popd
  • To update the Python dependencies:
$ pushd ~/dev/geo/opentraveldata-qa
$ pipenv update
$ git add Pipfile.lock
$ pipenv lock -r > requirements.txt
$ git add requirements.txt
$ git commit -m "[Python] Upgraded the Python dependencies"
$ git push
$ popd

Launch the Python checkers

  • Use the Makefile to launch all the checkers (previous content may first be removed, for instance if they have been generated another day):
$ rm -f to_be_checked/* && rm -f results/*
$ make
  • Use pipenv to launch specific Python scripts. For instance:
$ pipenv run python checkers/check-por-cmp-optd-unlc.py
$ pipenv run python checkers/check-por-geo-id-in-optd.py
  • Or use a convenient shortcut provided by the Makefile approach:
$ make results/optd-qa-por-optd-not-in-unlc.csv
pipenv run python checkers/check-por-cmp-optd-unlc.py && \
	wc -l results/optd-qa-por-unlc-not-in-optd.csv results/optd-qa-por-optd-not-in-unlc.csv && head -3 results/optd-qa-por-unlc-not-in-optd.csv results/optd-qa-por-optd-not-in-unlc.csv

  • By default, the number of replicas is 1, i.e., the index is replicated once. That is not possible on single-node clusters. Hence, the health of the index will appear in yellow. To fix that issue, from within the browser, with the Kibana application, edit the settings of the optd-qa-por-full-v1 index (http://localhost:5601/app/kibana#/management/elasticsearch/index_management/indices) and set the number_of_replicas parameter to 0 (instead of 1). Save the setiings. The health parameter should now be green. Or, with the command-line:

Todo

As of April 2020, the resulting CSV data files have various formats. Dumping the corresponding content into Elasticsearch (ES) would force to have almost an index per CSV file type, which would slightly defeat the interest of using ES. Rather, it seems better to merge all the CSV file types into a single format, allowing to get a single ES index. Then, every CSF file will be tagged with their respective checking intent. The search and time-series analysis will be much easier. So, the next step is to merge all the formats of the CSF files.

POR having no geo-location in OPTD

  • That script spots POR missing geo-location in the OPTD public POR file. It generates a CSV file:

    • results/optd-qa-por-optd-no-geocoord.csv, reporting the POR having no geo-location (geo-coordinates)
  • Note that if a CSV file has a single row, it is the header. So, it can be considered as empty.

OPTD vs IATA

  • That script compares the OPTD-referenced POR having a UN/LOCODE code with the ones referenced by IATA. It has to be noted that the Python script first downloads the iata_airport_list_latest.csv file, which is actually a symbolic link. Then, the Python script downloads the actual data file, say for instance archives/iata_airport_list_20190418.csv. The script then generates a few CSV files:

    • results/optd-qa-por-optd-no-it.csv, exhibiting the POR referenced by OPTD but not by IATA
    • results/optd-qa-por-it-not-optd.csv, exhibiting the POR referenced by IATA but not by OPTD
    • results/optd-qa-por-it-no-valid-in-optd.csv, exhibiting the POR referenced by IATA but no longer valid in OPTD
    • results/optd-qa-por-it-in-optd-as-city-only.csv, exhibiting the POR referenced by OPTD only as cities (whereas they appear in IATA also as transport-/travel-related)
    • results/optd-qa-state-optd-it-diff.csv, exhibiting the POR having different state codes in IATA and OPTD
  • Note that if a CSV file has a single row, it is the header. So, it can be considered as empty.

State codes

  • The checker is the same as above (checkers/check-por-cmp-optd-it.py)

  • Check the number of POR having different state codes, broken down by country:

$ awk -F'^' '{print $8}' results/optd-qa-state-optd-it-diff.csv|sort|uniq -c|sort -nr|head -5
 342 CN
 288 FR
 185 DE
 175 GB
 138 RU$ 
  • Check the number of POR having differrent state codes for a specific country:
$ awk -F'^' '{if ($8 == "CN") {print $8 "^" $7 "^" $12}}' results/optd-qa-state-optd-it-diff.csv|sort|uniq -c|sort -nr|head -5

OPTD vs UN/LOCODE

  • That script compares the OPTD-referenced POR having a UN/LOCODE code with the ones referenced by UN/LOCODE. It generates two CSV files:

    • results/optd-qa-por-optd-not-in-unlc.csv, exhibiting the POR referenced by OPTD but not by UN/LOCODE
    • iresults/optd-qa-por-unlc-not-in-optd.csv, exhibiting the POR referenced by UN/LOCODE but not by OPTD
  • Note that if a CSV file has a single row, it is the header. So, it can be considered as empty.

$ pushd ~/dev/geo/opentraveldata-qa
$ pipenv run checkers/check-por-cmp-optd-unlc.py
$ wc -l results/optd-qa-por-unlc-not-in-optd.csv
10349 results/optd-qa-por-unlc-not-in-optd.csv

-rw-r--r-- 1 user staff 763K Dec 13 18:22 results/optd-qa-por-unlc-not-in-optd.csv
$ popd
  • In order to get the IATA-referenced POR out of UN/LOCODE-referenced ones:
$ pushd ~/dev/geo/opentraveldata-qa
$ awk -F'^' '{if ($2 != "") {print $0}}' results/optd-qa-por-unlc-not-in-optd.csv | wc -l

$ popd

Airlines

Airport Bases / Hubs

$ pushd ~/dev/geo/opentraveldata-qa
$ ./mkLocalDir.sh
$ pipenv run python checkers/check-airline-bases.py
$ wc -l results/optd-qa-airline-bases-not-in-flight-legs.csv

$ popd

If the script does not return anything, then the check (successfully) passes.

Airline networks

  • That script performs, for every airline of the optd_airlines.csv file, some basic statistics on their network, modelled as graph (where POR are nodes and flight segments/legs are edges):
$ pushd ~/dev/geo/opentraveldata-qa
$ pipenv run checkers/check-airline-networks.py
$ wc -l results/optd-qa-airline-network-far-nodes.csv
