boost.graph external properties question.

HI,
I'm starting a project that uses boost.graph and I'm trying to decide if
I should use internal or external properties.
My code that implements external properties is like, for example:
typedef boost::graph_traits <GraphT>::vertex_descriptor Vertex;
typedef std::map

No, it is not guaranteed that vertex descriptors from different graphs are distinct. In fact, they will very often be the same: when using adjacency_list with VertexListS = vecS, vertex descriptors are always integers between 0 and num_vertices(g).
That is, can I instanciate 2 GraphT objects and populate both, but maintain only one VertexData container?
Not unless you want to make the key type std::pair
