       User::Identity - maintains info about a physical person


          is a User::Identity::Item


        use User::Identity;
        my $me = User::Identity->new
         ( 'john'
         , firstname => 'John'
         , surname   => 'Doe'
        print $me->fullName  # prints "John Doe"
        print $me;           # same


       The "User::Identity" object is created to maintain a set of informational objects which
       are related to one user.  The "User::Identity" module tries to be smart providing
       defaults, conversions and often required combinations.

       The identities are not implementing any kind of storage, and can therefore be created by
       any simple or complex Perl program.  This way, it is more flexible than an XML file to
       store the data.  For instance, you can decide to store the data with Data::Dumper,
       Storable, DBI, AddressBook or whatever.  Extension to simplify this task are still to be

       If you need more kinds of user information, then please contact the module author.



           When an "User::Identity" is used as string, it is automatically translated into the
           fullName() of the user involved.


            my $me = User::Identity->new(...)
            print $me;          # same as  print $me->fullName
            print "I am $me\n"; # also stringification


       User::Identity->new([NAME], OPTIONS)

           Create a new user identity, which will contain all data related to a single physical
           human being.  Most user data can only be specified at object construction, because
           they should never change.  A NAME may be specified as first argument, but also as
           option, one way or the other is required.

           Calcuted from the datge of birth to the current moment, as integer.  On the birthday,
           the number is incremented already.


           Returns the date in standardized format: YYYYMMDD, easy to sort and select.  This may
           return "undef", even if the dateOfBirth() contains a value, simply because the format
           is not understood. Month or day may contain '00' to indicate that those values are not


           The user's prefered character set, which defaults to the value of LC_CTYPE environment


           The courtesy is used to address people in a very formal way.  Values are like "Mr.",
           "Mrs.", "Sir", "Frau", "Heer", "de heer", "mevrouw".  This often provides a way to
           find the gender of someone addressed.


           Returns the date of birth, as specified during instantiation.


           See "Attributes" in User::Identity::Item


           Returns the first name of the user.  If it is not defined explicitly, it is derived
           from the nickname, and than capitalized if needed.


           Returns a formal name for the user.  If not defined as instantiation parameter (see
           new()), it is constructed from other available information, which may result in an
           incorrect or an incomplete name.  The result is built from "courtesy initials prefix
           surname title".


           If this is not specified as value during object construction, it is guessed based on
           other known values like "firstname prefix surname".  If a surname is provided without
           firstname, the nickname is taken as firstname.  When a firstname is provided without
           surname, the nickname is taken as surname.  If both are not provided, then the
           nickname is used as fullname.


           Returns the specified gender of the person, as specified during instantiation, which
           could be like 'Male', 'm', 'homme', 'man'.  There is no smart behavior on this: the
           exact specified value is returned. Methods isMale(), isFemale(), and courtesy() are


           The initials, which may be derived from the first letters of the firstname.


           See isMale(): return true if we are sure the user is a woman.


           Returns true if we are sure that the user is male.  This is specified as gender at
           instantiation, or derived from the courtesy value.  Methods isMale and isFemale are
           not complementatory: they can both return false for the same user, in which case the
           gender is undertermined.


           Can contain a list or a single language name, as defined by the RFC Examples are 'en',
           'en-GB', 'nl-BE'.  The default language  is 'en' (English).


           See "Attributes" in User::Identity::Item


           Returns the user's nickname, which could be used as username, e-mail alias, or such.
           When no nickname was explicitly specified, the name is used.


           The words which are between the firstname (or initials) and the surname.


           Returns the surname of person, or "undef" if that is not known.


           The titles, degrees in education or of other kind.  If these are complex, you may need
           to specify the formal name of the users as well, because smart formatting probably

       Error: Cannot load collection module for $type ($class).

           Either the specified $type does not exist, or that module named $class returns
           compilation errors.  If the type as specified in the warning is not the name of a
           package, you specified a nickname which was not defined.  Maybe you forgot the
           'require' the package which defines the nickname.

       Error: Creation of a collection via $class failed.

           If you add a collection, it must either by a collection object or a list of options
           which can be used to create a collection object.  In the latter case, the type of
           collection must be specified.
