Last year I started playing around with the Solid platform, introduced by Tim Berners-Lee. In order to get more familiar with the different concepts and technologies used, I created a proof-of-concept app: a browser chess game. The main concept of the Solid platform is the use of Solid PODs, which provide personal online data storage. The idea of Solid is that a user has one or more PODs to store their data and different apps are able to interact with these PODs, but these apps can only read and write the data to which the user has granted them access. So, instead of having to store all data of all users on a single server per app, users now store and control (!) their own data, leading to a decentralized approach. The focus of this blog post is on the interaction between the app and the Solid PODs.
