Hi folks, I am using the BGL and now I want to serialize the graph. Serialization of the vertices and edges works fine, but how do I serialize the vertex|edge properties? My properties and graph definition are the following: <code> struct vertex_cId_t { typedef vertex_property_tag kind; }; struct vertex_cType_t { typedef vertex_property_tag kind; }; struct vertex_cShape_t { typedef vertex_property_tag kind; }; struct edge_cType_t { typedef vertex_property_tag kind; }; struct edge_cColor_t { typedef vertex_property_tag kind; }; namespace boost { BOOST_INSTALL_PROPERTY(vertex, cId); BOOST_INSTALL_PROPERTY(vertex, cType); BOOST_INSTALL_PROPERTY(vertex, cShape); BOOST_INSTALL_PROPERTY(edge, cType); BOOST_INSTALL_PROPERTY(edge, cColor); } typedef property CVertexId; typedef property CVertexShape; typedef property CVertexAttribute; typedef property CEdgeColor; typedef property CEdgeAttribute; typedef adjacency_list Graph; </code> How must the serialize functions for CVertexAttribute and CEdgeAttribute look like? Thanks in advance. David
