Hi

nice modeling. Is the annotated data model in the direction of defining
also a parsing model?


for the
EXAMPLE 2
name,street,city,country,street1,city1,country1

i would suggest instead using something like:
name,street_1,city_1,country_1,street_2,city_2,country_2

for the rewrites, as it permits to deduce the original column name and order
