Here is an example excerpt to use graph properties and access it.

enum my_graph_name_t { my_graph_name = 3333 };

typedef property<my_graph_name_t, std::string> GP;
typedef adjacency_list<boost::vecS, boost::vecS, boost::directedS,
                       no_plugin, no_plugin, GP> Graph_With_GraphProperty;

//....

template <class Graph>
void foo(Graph& g) {
 typedef typename graph_property<Graph, my_graph_name_t>::type NameType;
 NameType& g_name = get_property(g, graph_name);
 //...
}
