---------------------------------------------

Hi Manuel, could you indicate steps to reproduce the described problems?

To your question "how will I create a MGraph that shouldn't externalize its literals?" That's not currently possible (apart from the hacks you describe), but I think this is a more general issue, there is no support to somehow constrain the TcProvider chosen, triple collcetions are always created ba the one with the highest priority. It might be desirable to be able to tell the TcManager what the requirement are and that the best provider for that purpose is chosen (criteria might be read-performance, write-performance, size, leanification, ...).

> As binary resources are stored as literal values in the graph inserting literals of many MB is not a seldom usage scenario. Inserting such literals however take very long and thus require a very long write-lock on the graph (e.g. on my laptop 9 seconds when uploading a 40MB file with TDB and 3 second with Sesame)
