Solid changes the current model where users have to hand over personal data to digital giants in exchange for perceived value. As we’ve all discovered, this hasn’t been in our best interests. Solid is how we evolve the web in order to restore balance — by giving every one of us complete control over data, personal or not, in a revolutionary way. Tim Berners-Lee
You own your data, and choose apps to manage it
Within the Solid ecosystem, you decide where you store your data. Photos you take, comments you write, contacts in your address book, calendar events, how many miles you run each day from your fitness tracker… they’re all stored in your Solid POD. This Solid POD can be in your house or workplace, or with an online Solid POD provider of your choice. Since you own your data, you’re free to move it at any time, without interruption of service.
You give people and your apps permission to read or write to parts of your Solid POD. So whenever you’re opening up a new app, you don’t have to fill out your details ever again: they are read from your POD with your permission. Things saved through one app are available in another: you never have to sync, because your data stays with you.
This approach protects your privacy and is also great for developers: they can build cool apps without harvesting massive amounts of data first. Anyone can create an app that leverages what is already there.
Your pod is your personal storage space
Store anything you want in your own Solid POD. PODs are like secure USB sticks for the Web, that you can access from anywhere. When you give others access to parts of your POD, they can react to your photos and share their memories with you. You decide which things apps and people can see.
Think of your Solid POD as your own private website, except that your data interoperates with all your apps, which means you have your own personal API to go along with it. When you post comments or videos online, your friends can view them with whatever app they like, such as an album viewer or a social feed. It’s your data, that can be shaped in any way or form.
