Open Numbers: Crowd-sourced harmonization of global & local statistics
It’s a community for data-crunchers who harmonize statistics to make them more useful for a fact-based worldview. Gapminder moderates the process to make sure people participating know what they are doing.
Dans Open Numbers, chaque jeu de données est structuré suivant le modèle DDF. 4 éléments : DataPoints (“simple data storage”), Entities (“defining single-dimensional data”), Concepts (“giving information about your column headers”), Metadata (“giving information about your data”) => simili SDMX.
Les données sont stockées en csv (mais pas obligatoirement).
Usage final d’Open Numbers : assemblage de jeux de données pour visualisation dans l’outil Gapminder.
Systema Globalis (main dataset used in tools on the official Gapminder website. It contains local & global statistics combined from hundreds of sources)
2017-09-26 Discussion with Jasper Heeffer (Gapminder / Open Numbers)
Gapminder 7 people team, including 2 developers (some things outsourced).
The old Gapminder World graph used Flash and data on Google Spreadsheet. Open Numbers started about 1,5 years ago for the new version of Gapminder Tools.
Data is stored in CSV because it’s easy to work with, that’s what researchers want, to dig in, create their own dataset, etc.
However CSV is not the best to fetch things from, it’s not optimised for queries.
DB.nomics is kind of creating the “data architecture”, with a platform on which you could build other projects on the user-side: vizualisation, reuse, mixing, harmonization, etc.
Users can be individuals but also other websites/platforms
Gapminder could be one of these users, focused on the dataviz, since the architecture (fetching, agregating, etc.) is not their strength. Data.world : similar idea
