Parsing hydra as RDF graph

Greetings list,

i'm using the https://api-platform.com/ (which is great btw) server side
and the rdflib.js (https://github.com/linkeddata/rdflib.js) client side
playing around with rdf graphs.

When i'm parsing the jsonld as RDF graph i get a lot of blank nodes. Which
may not seem as a problem at first, but the same blank nodes, are assigned
a new id every time they are mentioned. I'm not sure if we can refer to a
blank node the same way we can with a named one.

Have a look at the example here

PS: I'll check rdflib.js also
