Hi Mike,

please see Table 1 the last part on PropertyGraph on
http://www.boost.org/doc/libs/1_43_0/libs/graph/doc/graph_concepts.html

You need first to get the property_map, which is the central concept to 
graph-/vertex-/edge-properties.

You might try something like:
(get(graph_properties, g))[g].bobo

Hope that helps.

Best,

Cedric
