import RDF data from vCard format

NAME

RDF::vCard::Importer - import RDF data from vCard format

SYNOPSIS

 use RDF::vCard;
 use RDF::TrineShortcuts qw':all';
 
 my $importer = RDF::vCard::Importer->new;
 print $_
        foreach $importer->import_file('contacts.vcf');
 print rdf_string($importer->model => 'RDFXML');

DESCRIPTION

This module reads vCards and writes RDF.

Constructor

•

new(%options)

Returns a new RDF::vCard::Importer object and initialises it.

The only valid option currently is ua which can be set to an LWP::UserAgent for those rare occasions that the Importer needs to fetch stuff from the Web.

Methods

•

"init"

Reinitialise the importer. Forgets any cards that have already been imported.

•

"model"

Return an RDF::Trine::Model containing data for all cards that have been imported since the importer was last initialised.

•

"import_file($filename, %options)"

Imports vCard data from a file on the file system.

The data is added to the importer's model (and can be retrieved using the "model" method).

This function returns a list of RDF::vCard::Entity objects, so it's also possible to access the data that way.

There is currently only one supported option: "lang" which takes an ISO language code indicating the default language of text within the vCard data.

•

"import_fh($filehandle, %options)"

As per "import_file", but operates on a file handle.

•

"import_string($string, %options)"

As per "import_file", but operates on vCard data in a string.

•

import_url($url)

As per "import_file", but fetches vCard data from a Web address.

Sends an HTTP Accept header of:

  text/directory;profile=vCard,
  text/vcard,
  text/x-vcard,
  text/directory;q=0.1

vCard Input

vCard 3.0 should be supported fairly completely. Some vCard 4.0 constructs will also work.

Much of the heavy lifting is performed by Text::vFile::asData, so this module may be affected by bugs in that distribution.

RDF Output

Output uses the newer of the 2010 revision of the W3C's vCard vocabulary <http://www.w3.org/Submission/vcard-rdf/>. (Note that even though this was revised in 2010, the term URIs include "2006" in them.)

Some extensions from the namespace <http://buzzword.org.uk/rdf/vcardx#> are also output.

The AGENT property is currently omitted from output. This will be added in a later version.
