VERSION
version 3.0101
SYNOPSIS
use File::Sticker::Reader;
my $obj = File::Sticker::Reader->new(%args);
my $meta = $obj->read_meta($filename);
DESCRIPTION
This will read meta-data from files in various formats, and standardize it to a common nomenclature, such as "tags" for things called tags, or Keywords or Subject etc.
The standard nomenclature is:
- url
-
The source URL of this file (ref 'dublincore.source')
- creator
-
The author or artist who created this. (ref 'dublincore.creator')
- title
-
The title of the item. (ref 'dublincore.title')
- description
-
The description of the item. (ref 'dublincore.description')
-
The item's tags. (ref 'Keywords').
Other fields will be called whatever the user has pre-configured.

METHODS
new
Create a new object, setting global values for the object.
my $obj = File::Sticker::Reader->new();
init
Initialize the object. Set which fields you are interested in ('wanted_fields').
$reader->init(wanted_fields=>{title=>'TEXT',count=>'NUMBER',tags=>'MULTI'});
name
The name of the reader; this is basically the last component of the module name. This works as either a class function or a method.
$name = $self->name();
$name = File::Sticker::Reader::name($class);
priority
The priority of this reader. Readers with higher priority get tried first. This is useful where there may be more than one possible meta-data format for a file, such as EXIF versus XATTR.
This works as either a class function or a method.
This must be overridden by the specific writer class.
$priority = $self->priority();
$priority = File::Sticker::Reader::priority($class);
allow
If this reader can be used for the given file, and the wanted_fields then this returns true. Returns TRUE if there are no wanted_fields.
if ($reader->allow($file))
{
....
}
allowed_file
If this reader can be used for the given file, then this returns true. This must be overridden by the specific reader class.
if ($reader->allowed_file($file))
{
....
}
known_fields
Returns the fields which this reader knows about.
This must be overridden by the specific reader class.
my $known_fields = $reader->known_fields();
read_meta
Read the meta-data from the given file.
This must be overridden by the specific reader class.
my $meta = $reader->read_meta($filename);
