NAME

Parse::ACNS - parser for Automated Copyright Notice System (ACNS) XML

SYNOPSIS

    use Parse::ACNS;
    my $data = Parse::ACNS->new->parse( XML::LibXML->load_xml( string => $xml ) );

DESCRIPTION

ACNS stands for Automated Copyright Notice System. It's an open source, royalty free system that universities, ISP's, or anyone that handles large volumes of copyright notices can implement on their network to increase the efficiency and reduce the costs of responding to the notices...

See http://acns.net for more details.

This module parses ACNS XML into a perl data structure. Supports 1.2, 1.1, 1.0, 0.7 and 0.6 revisions of the spec. Parser strictly follows XML Schemas, so throws errors on malformed data.

However, it doesn't extract ACNS XML from email messages.

SOME ACNS BACKGROUND

NBC Universal and UMG released two revisions of the spec (0.6 and 0.7).

Motion Picture Laboratories, Inc. took over and named it ACNS 2.0 and released revisions 1.0, 1.1 and several sub-revisions with letters (1.1f, 1.1j, 1.1p).

Then it was moved once again to http://www.acns.net/spec.html and revision 1.2 was released.

METHODS

new

Constructor, takes list of named arguments.

version - version of the specification

compat

default value, can parse 1.2 to 0.6 XML. Revision 1.2 is backwards compatible with 0.7. Compat schema makes TimeStamp in Infringement/Content/Item optional to make it compatible with 0.6 revision. Everything else new in 1.2 is optional.

1.2, 1.1, 1.0, 0.7 or 0.6

strict parsing of the specified version.

parse

    my $data = Parse::ACNS->new->parse( XML::LibXML->load_xml(...) );

Takes XML::LibXML::Document containing an ACNS XML and returns it as a perl struture. Read XML::LibXML::Parser on parsing from different sources.

Newer versions of the spec describe more messages besides <Infringement>, for example <StatusUpdate>. Top level element is not returned as part of the result, but you always can get it from XML document:

    $xml_doc->documentElement->nodeName;

To simplify implementation of compat version parsing document can be changed. At this moment XML namespace is adjusted on all elements.

Returned data structure follows XML and its Schema, for example:

    {
        'Case' => {
            'ID' => 'A1234567',
            'Status' => ...,
            ...
        },
        'Complainant' => {
            'Email' => 'antipiracy@contentowner.com',
            'Phone' => ...,
            ...
        },
        'Source' => {
            'TimeStamp' => '2003-08-30T12:34:53Z',
            'UserName' => 'guest',
            'Login' => { ... },
            'IP_Address' => ...,
            ...
        }
        'Service_Provider' => { ... }
        'Content' => {
            'Item' => [
                {
                    'TimeStamp' => '2003-08-30T12:34:53Z',
                    'FileName' => '8Mile.mpg',
                    'Hash' => {
                            'Type' => 'SHA1',
                            '_' => 'EKR94KF985873KD930ER4KD94'
                          },
                    ...
                },
                { ... },
                ...
            ]
        },
        'History' => {
            'Notice' => [
                {
                    'ID' => '12321',
                    'TimeStamp' => '2003-08-30T10:23:13Z',
                    '_' => 'freeform text area'
                },
                { ... },
                ...
            ]
        },
        'Notes' => '
            Open area for freeform text notes, filelists, etc...
        '
    }
