RDF::vCard::Importer(3) import RDF data from vCard format


use RDF::vCard;
use RDF::TrineShortcuts qw':all';

my $importer = RDF::vCard::Importer->new;

foreach $importer->import_file('contacts.vcf');
print rdf_string($importer->model => 'RDFXML');


This module reads vCards and writes RDF.


  • "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.


  • "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:


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.
