Dear Jeremiah,

It looks like property_map is the right name.  Could you please post the entire file so I know which line numbers those errors are referring to?

Sure. Please find that in the attachments.

The output of property_map<...>::type is a property map, not the value type of the property map. Thus, the property map cannot be assigned to a variable of type string. If you want the map's value type, use property_traits::type>::value_type. -- Jeremiah Willcock
