The 2013 edition of the ISO 3166 series has been the last one published as paper standard, with the descriptive text, and the codes together.
At the end of 2013, the split had happened: ISO 3166 codes have been moved to the database format (de facto merging three contents together), with access from ISO Online Browsing Platform, while the descriptive text has been awaiting updates.
ISO 3166-1:2020 edition of the ISO 3166 series includes an update of the descriptive text (description of the codes) from 2013, for each of three parts. It takes into account the stricter database rules imposed on the code itself, as opposed to paper documents.
ISO 3166-1:2020 has been the very first ISO achievement of the concept of “standard as a database”, implemented in the end of 2013. The ISO OBP (Open Browsing Platform) is an application to visualize ISO3166 codes on the web interface, the data being stored in the unseen database.
ISO 3166-1:2020, for each of its three parts – three codes – is formed of two components: documented description of its content, and its related content inside a database.
