If you read TriG into model, it takes the default graph only.
The TriG has a named graphs in it. bdg:T1642 { ... }
Remove the name and it should work.
The Turtle does not have a name (so it is the same as Trig+default graph)

Hi Martynas !
The method you are pointing me to effectively works and I can use it to solve
the issue for now. However, the RDFDataMgr documentation says (about read
methods/operations):
read -- Read data from a location into a Model, Dataset, etc. The methods in
this class treat all types of Model in the same way. For behavior specific to a
subtype of Model, use the methods of that specific class.
Therefore, both

should work.
I am wondering why they don't: Am I using them wrongly or is this just a bug ?

I think you want to read a Dataset:

Hi all,
I need to build Models or Graphs from strings being a trig serialization
of a rdf resource.
I tried to do using Model.read or RDFDataMgr but both produce empty models
or graphs.
When I do the same operation with Turtle serialization, it works just fine.
What do you think ?
Run the following code to see that by yourself:
