We created OPDS with the following things in mind:
Today, every user expect to instantly browse, search and download content right from their device.
Too often though, this ease of use comes at a huge cost: your own freedom to move from one platform to another.
You're not allowed to get anything in or out of these fences, and you don't actually own your content.
In the physical world, we're used to acquire content from multiple places.
Purchasing is not the only option, we can also borrow or get a subscription.
With OPDS, you can access content from any source, on any device.
Any developer can create a client, any content provider can do distribution.
It's the best of both worlds: easy to use, yet open and decentralized.
