Hmm, I don't have a clue what exactly you mean.
By "binary attribute" do you mean an EAttribute with an own EDataType?
How is a file related to this?
I fear you'll have to explain it in more detail.

Simon,
If the data is "attached" to the model (at client side) through the use
of an EDataType it gets serialized to a String. Your (generated)
EPackage has control over the exact format. Although this might not be
the perfect way to handle huge amounts of binary data I don't see an
alternative if you insist on accessing it by EMF means.
Of course you could use plain Net4j to develop an own protocol that
optimizes the handling of huge data blocks / streams. But how would that
be connected to EMF / Ecore?
Cheers
