Yes, I know that there are approaches which use the normal file system.

But what I want is different:

I want a universial "DB for binary files" where I can store binary data and all its metadata.

Then I can use this DB to build a app for picture galleries, music collections and tons of other things.

This DB should also support:

* automatic checksumming so that I can detect data corruption

* Some sort of version history so that I can store multiple versions of a file

* there could be built-in replication which I can use to see the same data (or parts of it) on all my devices
