So i thought turning the writer into an inputstream and reading it into dataset
with RDFDataMgr.read would do it's job
InputStream writerStream = new
ByteArrayInputStream(writer.toString().getBytes(StandardCharsets.UTF_8));
RDFDataMgr.read(dataset, writerStream, Lang.NQUADS);
But i get:
Exception in thread "main"

Betreff: Re: Storing ThingDescription in Dataset
It has N-Quads reader and writer, so write the RdfDataset as N-Quads to bytes
or a string, and parse that. Not ideal at scale but it works; JSON-LD isn't
streaming anyway.
