=head1 NAME
Data::OFAC - A Perl interface to the United States Office of Foreign Assets
Control (OFAC) Specially Designated Nationals List (SDN)
=head1 VERSION
Version 0.80
=cut
our $VERSION = '0.80';
=head1 DESCRIPTION
From OFAC's Website:
As part of its enforcement efforts, OFAC publishes a list of
individuals and companies owned or controlled by, or acting for or on
behalf of, targeted countries. It also lists individuals, groups, and
entities, such as terrorists and narcotics traffickers designated under
programs that are not country-specific. Collectively, such individuals
and companies are called "Specially Designated Nationals" or "SDNs."
Their assets are blocked and U.S. persons are generally prohibited from
dealing with them.
This interface is helpful for insitutions that use Perl, and may have a
need to screen individuals as potential customers.
Note that this module will require occasional internet access if
auto_update is enabled. Auto update contacts OFAC's website to download
the latest SDN list in "CSV" format. These files are used to build a SQLite
database. In order to remain "compliant" reasonably frequent updates are
recommended. For financial institutions, not complying with this carries
heavy penalties. I am not a lawyer, and I cannot recommend your update
frequency. I've set 12 hours as I believe this to be a reasonable update
interval. Again, this module carries no waranty, and cannot be a full
replacement for full compliance with the regulations. YMMV.
=head1 SYNOPSIS
A simple example.
use Data::OFAC;
my $ofac = Data::OFAC->new(
auto_update => 1,
auto_update_frequency => 12,
database_file => '/path/to/sdn.sqlite'
);
my $result = $ofac->checkString($string);
if ( defined $result ) {
print "Hit found:" .
Dumper $result; # varries by hit, but is just a hash.
}
...
=head1 SUBROUTINES/METHODS
=head2 new
Instantiates the base object. Note that the following parameters are
currently supported:
=head3 auto_update [0,1] (Optional)
Tells Data::OFAC whether you desire to update the database. It will check a
table in SQLite to determine the last update date/time and decide if
checking for a new update is warranted. Note that the download is not
particularly large, but the download and subsequent rebuild of the database
could introduce a startup penalty that may be undesirable. (30 seconds on my
quad core MBP) For long running processes, there is no present method for
updating on the fly. Since I run this as part of a larger web service, my
processes cycle frequently enough that I never have this problem. YMMV
0 - disable
1 - enable *default
=head3 auto_update_frequency [int] (Optional)
Sets the desired delay between rechecks. Data::OFAC will recheck at each
start if the auto_update property is set to 1.
Default: 12 (hours)
=head3 database_file [string] (Optional)
Sets the desired location to keep the database file. The default is your
home directory in the ".ofac" directory.
Default: $ENV{HOME}/.ofac/sdn.sqlite or $ENV{USERPROFILE}\.ofac\sdn.sqlite

=head2 checkString
Checks the specified string against all fields.
my $result = $ofac->checkString("String");
=cut
sub checkString {
my $self = shift;
my $string = shift;
my $opts = shift;
my $resultset;
my @columns = qw{sdn_name title};
for (qw {Sdn SdnComment}) {
$resultset->{$_} = $self->{sdn}->search( $_, $string, @columns );
}
@columns = qw{alt_name};
$resultset->{Alt} = $self->{sdn}->search( 'Alt', $string, @columns );
@columns = qw{citystateprovincepostalcode country};
$resultset->{Address}
= $self->{sdn}->search( 'Address', $string, @columns );
return $resultset;
}
=head2 checkAddress
Checks the specified array against the address table. Note the Country must be
spelled out I.E. Nigeria
my $result =
$ofac->checkAddress("City, State, Province, Postal Code", "Country");
=cut
sub checkAddress {
my $self = shift;
my $address = shift;
my $country = shift;
return $self->{sdn}->searchAddress( $address, $country );
}
=head2 checkName
Checks the specified name against the SDN and ALT tables. Note that for the
best match, supply an individual's name in "Lastname, Firstname" format. For
corporations, supply in regular format.
=cut
sub checkName {
my $self = shift;
my $name = shift;
my $resultset;
my @columns = qw{sdn_name title};
for (qw {Sdn SdnComment}) {
$resultset->{$_} = $self->{sdn}->search( $_, $name, @columns );
}
@columns = qw{alt_name};
$resultset->{Alt} = $self->{sdn}->search( 'Alt', $name, @columns );
return $resultset;
}
=head2 checkStatus
Checks for the database status after startup. Returns "dirty" or "clean". Handy
for determining the validity of the data being returned. Dirty just indicates
that the database hasn't been updated recently.
=cut
sub checkStatus {
return $_->{_status};
}
=head2 willUpdate
Checks if the next search call will force a database update. If yes, the call
will return "defined" or 1. Helpful if your application is timing sensitive to
prespin the update before your next search. Note that at this time, updating is
a blocking call.
=cut
sub willUpdate {
( time() - $_->{sdn}->{_lastupdate} )
>= ( $_->{auto_update_frequency} * 60 * 60 )
&& return 1;
return undef;
}
=head2 forceUpdate
Force the update of the database. Will cause a database update to occur. Note
that this call still blocks, but is handy if you want an out-of-band process
to handle the updating.
=cut
sub forceUpdate {
my $self = shift;
return $self->{sdn}->updateDatabase();
}
