TriG has been issued as a W3C recommendation, as part of the RDF 1.1 suite. This allows graph names (note the plural!) to be included in a TTL file. What plans to implement this in TopBraid? I can see it will be a big job, because currently TopBraid uses the ontology URI as the graph name internally (and usually expects it to correspond with the file name) so supporting named graphs properly would undermine this, or at least require you to call it 'context' rather than 'graph-name' or something similar ...
