Hello, welcome back to the Ruby Advent Calendar 2017. Let’s continue the series on Day 22 with datapak - Work with Tabular Data Packages (.CSV Files w/ datapackage.json) Using In-Memory SQLite (w/ ActiveRecord). All about open data, frictionless data, tabular data packages, core (open tabular) datasets and much more. Happy reading & querying. Cheers. PS: You’re more than welcome to send in your articles (about your library / gem of choice) too!
