NAME

  Data::Type - robust and extensible data- and valuetype system

VERSION

  0.02.01 (Wed Dec 1 21:33:51 2004)

DESCRIPTION

  This module delivers an easy, generic and unified interface to type
  related CPAN modules. They all have one common purpose: reporting if data
  has some "characteristics". And this module wraps that with a clean api.

SYNOPSIS

    use Data::Type qw(:is +ALL);

    is STD::EMAIL or warn;

    warn if isnt STD::CREDITCARD( 'MASTERCARD', 'VISA' );

    try
    {
      valid( '9999-12-31 23:59:59', DB::DATETIME );
    }
    catch Data::Type::Exception with
    {
      print $e->to_string foreach @_;
    };

EXAMPLES

  Visit the Data::Type::Docs::Howto to explore how to use this module for
  DBI, CGI, Getopt and more scenarios.

INSTALLATION

  I highly recommend to use CPAN for one-stop-shop installation:

  perl -MCPAN -e "install Data::Type"

SUPPORTED TYPES

  All types are grouped and though belong to a collection. The collection is
  identified by a short id. All members are living in a namespace that is
  prefixed with it (uppercased).

  Standard Collection ('STD')
     This is a heterogenous collection of datatypes which is loaded by
     default. It contains various issues from CPAN modules (i.e. business,
     creditcard, email, markup, regexps and etc.) and some everyday things.
     See Data::Type::Collection::Std.

  W3C/XML-Schema Collection ('W3C')
     A nearly 1-to-1 use of XML::Schema datatypes. It is nearly complete and
     works off the shelf. Please visit the XMLSchema
     <http://www.w3.org/TR/xmlschema-2/> homepage for sophisticated
     documentation. See Data::Type::Collection::W3C.

  Database Collection ('DB')
     Common database table types (VARCHAR, TINYTEXT, TIMESTAMP, etc.). See
     Data::Type::Collection::DB.

  Biological Collection ('BIO')
     Everything that is related to biological matters (DNA, RNA, etc.). See
     Data::Type::Collection::Bio.

  Chemistry Collection ('CHEM')
     Everything that is related to chemical matters (Atoms, etc.). See
     Data::Type::Collection::Chem.

  Perl5 Collection ('PERL')
     Reserved and undecided. See Data::Type::Collection::Perl.

  Perl6 Apocalypse Collection ('PERL6')
     Placeholder for the Apocalypse and Synopsis 6 suggested datatypes for
     perl6. See Data::Type::Collection::Perl6.

  [Note] "ALL" is a an alias for all available collections at once.

PREREQUISITES

  Following modules get automatically installed via the CPAN module. See
  INSTALLATION above. Data::Type has a mechanism for delayed loading of
  modules. This means modules are loaded only when the used types require
  them, not all at once.
