NAME
XML::Generator::vCard::RDF - generate RDF/XML SAX2 events for vCard 3.0

SYNOPSIS
use XML::SAX::Writer;
use XML::Generator::vCard::RDF;

my $writer = XML::SAX::Writer->new();
my $driver = XML::Generator::vCard::RDF->new(Handler=>$writer);

$driver->parse_files("test.vcf");

DESCRIPTION
Generate RDF/XML SAX2 events for vCard 3.0

DOCUMENT FORMAT
SAX2 events map to the *Representing vCard Objects in RDF/XML* W3C note:

http://www.w3.org/TR/2001/NOTE-vcard-rdf-20010222/

Additionally, an extra description will be added for each unique email
address. Each description will be identified by the value of SHA1 digest
of the address and simply point back to the vCard description.

For example, the test file for this package contains the email address
*[email protected]* which will cause the following description to be
added to the final output :

<rdf:RDF>
<rdf:Description rdf:about = 't/Senzala.vcf'>

</rdf:Description>



<rdf:Description rdf:about='http://xmlns.com/foaf/0.1/mbox_sha1sum#c0e0c54660f33a3ec7f22f902d0e5ead8bd4e4f4'>
<rdfs:seeAlso rdf:resource='t/Senzala.vcf' /></rdf:Description>
</rdf:Description>
</rdf:RDF>

This is done to facilitate merging vCard data with RDF representations
of email messages, using XML::Generator::RFC822::RDF. For example :

<rdf:RDF>

<rdf:Description rdf:about='x-urn:ietf:params:rfc822#5b0c8c9f9b2b782375f515a0b24b3a821a59a34a'>
<rfc822:To rdf:resource='http://xmlns.com/foaf/0.1/mbox_sha1sum#c0e0c54660f33a3ec7f22f902d0e5ead8bd4e4f4' />

</rdf:Description>

<rdf:Description rdf:about='http://xmlns.com/foaf/0.1/mbox_sha1sum#c0e0c54660f33a3ec7f22f902d0e5ead8bd4e4f4'>
<vCard:FN>Senzala Restaurant</vCard:FN>
<vCard:EMAIL>[email protected]</vCard:EMAIL>
</rdf:Description>

</rdf:RDF>

PACKAGE METHODS
__PACKAGE__->new(%args)
This method inherits from *XML::SAX::Base*

OBJECT METHODS
OBJECT METHODS
$pkg->parse_files(@files)
Generate SAX2 events for one, or more, vCard files.

Returns true or false.

$pkg->parse_files(@files)
PRIVATE METHODS
Private methods are documented below in case you need to subclass this
package to tweak its output.

$obj->_render_doc(\@vcards)
$obj->_render_card(Text::vCard)
$obj->_render_fn(Text::vCard)
$obj->_render_n(Text::vCard)
$obj->_render_nickname(Text::vCard)
$obj->_render_photo(Text::vCard)
$obj->_render_bday(Text::vCard)
$obj->_render_adrs(Text::vCard)
$obj->_render_labels(Text::vCard)
$obj->_render_tels(Text::vCard)
$obj->_render_emails(Text::vCard)
$obj->_render_instantmessaging(Text::vCard)
$obj->_render_mailer(Text::vCard)
$obj->_render_tz(Text::vCard)
$obj->_render_geo(Text::vCard)
$obj->_render_org(Text::vCard)
$obj->_render_title(Text::vCard)
$obj->_render_role(Text::vCard)
$obj->_render_logo(Text::vCard)
$obj->_render_categories(Text::vCard)
$obj->_render_note(Text::vCard)
$self->_render_sound(Text::vCard)
$self->_render_url(Text::vCard)
$obj->_render_key(Text::vCard)
$obj->_render_custom(Text::vCard)
By default this method does nothing. It is here to be subclassed.

$obj->_im_services()
Returns a hash ref mapping an instant messaging service type to an XML
element. Default is :

{"aim" => "foaf:aimChatID",
"yahoo" => "foaf:yahooChatID",
"msn" => "foaf:msnChatID",
"jabber" => "foaf:JabberID",
"icq" => "foaf:icqChatId"}

This is called by the *_render_instantmessaging* method.

BUGS
vCards containg binary PHOTO images may cause Perl to segfault on Mac
OSX and come flavours of Linux (but not FreeBSD.) The source of this
problem has been traced, I think, to a regular expression issue in the
Perl Text::ParseWords library. A bug report has been filed.

Please report all other bugs via http://rt.cpan.org
