Yes, and it's almost what we need. I think it's just too ossified to adapt to the few remaining shortcomings. Here's a couple: * Doesn't specify a federated authentication/authorization mechanism to allow self-hosted instances to work with each other. This includes things like how to have an app delegate permissions to other apps, ie for things like launcher apps which can open external apps and give them access to only specific files. * Doesn't specify a way to implement image thumbnails/previews, which is necessary for any sort of remote file explorer or gallery app.
