That's good, but is not enough. A metadata support would be useful!

e.g. It's like with photos (JPG) were you would only know it was shoot with a Canon camera, or a music file (MP3) that only stores the application name media player.

Most common file formats support metadata formarts like JPEG with its EXIV, ITPC, XMP and MP3 with ID3 v1 & v2, etc.

So for SQLite4 a very simple key value format would be great, with some predefined key-fields.

You can always embed a "metadata" table in your schema. Not ideal but would probably do the job in a lot of cases.
