DCAT-AP.de to CSV

requirements

  1. php >= 5.6
  2. composer https://getcomposer.org/

install

  1. Clone / Download Repository
  2. Run composer install

usage

To start the console run: php start.php

commands

get:packages

Downloads all available package meta data from https://open.nrw/api/3/action/current_package_list_with_resources

get:packages -m 5

Same as above, but limited to max. 5 packages

get:packages -h

Display all options for get:packages (there is also a limit and offset option)

Main package information is written to

  • output/packages.csv

Group and tag information is available in

  • output/groups.csv
  • output/tags.csv

limitations

Currently, it is only possible to comsume data from Open.NRW as the link to the CKAN API is hardcoded.
