Dataformat editor should be smarter
Currently, the dataformat editor relies on a CodeMirror widget that allows the user to input a JSON descriptor of the dataformat.
The dataformat is checked for conformance.
It would be nicer if the editor would, instead of providing a JSON text editor, would work like a wizard in which the user would go selecting (among possible options), existing dataformats in order to compose a new format. This would reduce development time and increase easeness of use.
