Second question because i update my program for use Stardog 7

I have an error when i write my code to add a file to stardog database

> starDogConnection.add().io().format().stream(new FileInputStream(path));

I don't understand which value i have to put in format() ?

> RDFFormat.BinaryRDFFormat give me an error : RDFFormat.BinaryRDFFormat cannot be resolved to a variable

Same for RDFFormat
