prov.read(source, format=None)

Convenience function returning a ProvDocument instance.

It does a lazy format detection by simply using try/except for all known formats. The deserializers should fail fairly early when data of the wrong type is passed to them thus the try/except is likely cheap. One could of course also do some more advanced format auto-detection but I am not sure that is necessary.

The downside is that no proper error messages will be produced, use the format parameter to get the actual traceback.
