# TM::Literal(3pm)

Topic Maps, simple values (literals)

## NAME

TM::Literal - Topic Maps, simple values (literals)

### SYNOPSIS

```
    use TM::Literal;
    my $l = new TM::Literal (42, 'xsd:integer');
    print $l->[0]; # prints 42
    print $l->[1]; # prints http://www.w3.org/2001/XMLSchema#integer
    $l = new TM::Literal (42); # default is xsd:string
```

## DESCRIPTION

This packages will eventually handle all literal handling, i.e. not only a way to create and retrieve information about simple values used inside topic maps, but also all necessary operations such as *integer addition*, *string manipulation*.

This is quite a chore, especially since the data types adopted here are the XML Schema Data Types.
