Re: [dotNetRDF-Support] dotNetRDF and Sesame REST service. Mime type exception

[Rob V. <rv...@do...>]

Tomasz

This looks like a simple typo on our part since the MIME type should be
"application/n-triples" - note the missing hyphen in your error message.
This will be fixed in default shortly and will be incorporated in our next
release

Thanks for reporting this,

Rob
