NAME
   Data::Semantic - Common API for data with semantics attached to them

VERSION
   version 1.101620

DESCRIPTION
   There are various distributions on CPAN dealing with data that has
   semantics attached them. For example, an IP address is not just a
   string, but it has a format the can be checked.

   There is Data::Domain. It does not store the values to be tested, it
   just tests them and records messages.

   Then there is Class::Value. It does store the value and it records
   exceptions.

   Both share the same underlying concept of a value that can be tested for
   validity. Data::Semantic provides this underlying mechanism. It does not
   store the value and it does not record the message. All it does is
   validate data and say whether it is good or bad. What Data::Domain or
   Class::Value do with this information is their thing.

   If you have a new type of semantic data, here is how you can handle it.

       if it can be a Regexp::Common pattern:
           make a Regexp::Common pattern
           make a subclass of Data::Semantic::RegexpAdapter
       else:
           make a subclass of Data::Semantic::Base
           if there is a CPAN module for that data type:
               wrap that module in your semantic data class
               forward methods onto the object if possible

       make an adapter class for Class::Value
       make an adapter class for Data::Domain

METHODS
 new
       my $obj = Data::Semantic->new;
       my $obj = Data::Semantic->new(%args);

   Creates and returns a new object. The constructor will accept as
   arguments a list of pairs, from component name to initial value. For
   each pair, the named component is initialized by calling the method of
   the same name with the given value. If called with a single hash
   reference, it is dereferenced and its key/value pairs are set as
   described before.
