Upgrading to RDF.ex 0.10

The only breaking change in this version is that the RDF.Turtle.Encoder no longer supports the encoding of RDF.Datasets. You'll have to aggregate an RDF.Dataset to an RDF.Graph on your own now. So, where you previously could do

RDF.Turtle.to_string(dataset)

you'll now have to do something like this

dataset
|> RDF.Dataset.graphs()
|> Enum.reduce(RDF.graph(), &RDF.Graph.add(&2, &1))
|> RDF.Turtle.to_string()

This change affects the SPARQL.Client, which needs to be upgraded to v0.4 to handle RDF.Datasets on the SPARQL.Client.insert_data/3 and SPARQL.Client.delete_data/3 functions.
