> Each application needs to understand not only the Solid protocol, but the format you are using for your data too. I don't think we'll be able to avoid that hurdle; we'll need to make sure that the protocol is really simple. But having to know the data format of the app itself is to be expected. If an app "instagram-on-solid" stores data in a certain way, the alternate app will need to understand those schemas as well to be compatible. That's how interop has always worked, even in the pre-internet age when we were exchanging files on disk. > It's been a while, have the applications improved? I haven't looked at apps in a while - but that was indeed moving very slowly.
