Indonesian property tax object number, or Nomor Objek Pajak Pajak Bumi dan
Bangunan, is a number given to a tax object (a piece of land with its
house/building).

NOP PBB is composed of 18 digits as follow:

 AA.BB.CCC.DDD.EEE-XXXX.Y

AA is the province code from BPS. BB is locality (city/regency a.k.a
kota/kabupaten) code from BPS. CCC is district (kecamatan) code from BPS. DDD is
village (desa/kelurahan) code from BPS. EEE is block code. XXXX is the object
number. Y is a special code (it is most likely not a check digit, since it is
almost always has the value of 0).

The function will return status 200 if syntax is valid and return the parsed
information hash. Otherwise it will return 400.

Currently the length and AA code is checked against valid province code. There
is currently no way to check whether a specific NOP PBB actually exists, because
you would need to query Dirjen Pajak's database for that.

 my $res = validate_nop_pbb(str => '327311000109900990');
 $res->[0] == 200 or die "Invalid NOP PBB!";

 # get structure
 use Data::Dumper;
 print Dumper $res->[2];

 # will print something like
 {
     province => 32,
     locality => 73,
     district => 110,
     village  => '001',
     block    => '099',

=head1 DESCRIPTION

This module provides one function: B<validate_nop_pbb>.

This module has L<Rinci> metadata.

=head1 FUNCTIONS


=head2 validate_nop_pbb

Usage:

 validate_nop_pbb(%args) -> [status, msg, payload, meta]

Validate (and parse) Indonesian property tax number (NOP PBB).

Indonesian property tax object number, or Nomor Objek Pajak Pajak Bumi dan
Bangunan, is a number given to a tax object (a piece of land with its
house/building).

NOP PBB is composed of 18 digits as follow:

 AA.BB.CCC.DDD.EEE-XXXX.Y

AA is the province code from BPS. BB is locality (city/regency a.k.a
kota/kabupaten) code from BPS. CCC is district (kecamatan) code from BPS. DDD is
village (desa/kelurahan) code from BPS. EEE is block code. XXXX is the object
number. Y is a special code (it is most likely not a check digit, since it is
almost always has the value of 0).

The function will return status 200 if syntax is valid and return the parsed
information hash. Otherwise it will return 400.

Currently the length and AA code is checked against valid province code. There
is currently no way to check whether a specific NOP PBB actually exists, because
you would need to query Dirjen Pajak's database for that.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

=over 4

=item * B<str> => I<str>

The input string containing number to check.

=back

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code
(200 means OK, 4xx caller error, 5xx function error). Second element
(msg) is a string containing error message, or 'OK' if status is
200. Third element (payload) is optional, the actual result. Fourth
element (meta) is called result metadata and is optional, a hash
that contains extra information.

Return value:  (hash)
