Portugal Grammar might need some work

[woodbri]

Here are some sample addresses from http://www.upu.int/fileadmin/documentsFiles/activities/addressingUnit/prtEn.pdf
The issue is how to handle sub-locality level 2 and sub-locality and locality.

Portugal has 18 districts which might be considered PROV but they do not explicitly come into play in the addresses. For Navteq data we can extract all the localities which would get tagged as CITY, and then potentially IGNORE the sub-localities.

The issue is not about recognizing them but how to categorize them when we pass them to the geocoder. We currently only CITY, PROV, NATION. We could stuff the CITY (aka: locality) into PROV and then put the sub-locality words into CITY.

Getting more addresses for Portugal and comparing them with real street data will probably make more sense of this.

The current grammar handles these by putting them into the extra field:

[macro]
@locality @postal @citywords @region @country
@locality @postal @citywords @country
@locality @postal @citywords @region
@locality @postal @citywords
@postal @citywords @region @country
@postal @citywords @country
@postal @citywords @region
@postal @citywords

[locality]
@word @locality
@word

[word]
WORD -> EXTRA -> 0.3

[citywords]
@city @citywords
@city
