Oh i'm alone here ;)
Ok for my last question i found myself the answer. Pffff ! Dia is very 
good but the doc is very light :)
for my problem i use "object_prop_by_name" like this :

dObj = (DiaObject *)list->data;
type = object_get_type(object_get_displayname(dObj));
if(!strcmp(type->name,IVR_BAY_BOUNDARY)){
	dia_assert_file(FALSE,"Boundary object found\n");
	/* test boundary begin */
	/*
	   get propertie
	   see lib/properties.h
	   see lib/prop_intypes.h
	   StringProperty : string_data
	   EnumProperty : enum_data
	*/
	prop = object_prop_by_name(dObj, "value");
	val = ((EnumProperty *)prop)->enum_data;
	if(val == BAY_BOUNDARY_BEGIN){
		/* ... */
	}
		
It's work... that's cool ! I like dia :)
It's time for me to finish my plugin.

Thanks for you attention ;)

Hum when my lib an plugin will be ready who i contact for a possible 
addition in dia ??
