NAME

Web::ID - implementation of WebID (a.k.a. FOAF+SSL)

SYNOPSIS

 my $webid = Web::ID->new(certificate => $pem_encoded_x509);
 if ($webid->valid)
 {
   say "Authenticated as: ", $webid->uri;
 }

DESCRIPTION

WebID is a simple authentication protocol based on TLS (Transaction Layer Security, better known as Secure Socket Layer, SSL) and the Semantic Web. This module provides a Perl implementation for authenticating clients using WebID.

For more information see the Web::ID::FAQ document.

Bundled with this module are Plack::Middleware::Auth::WebID, a plugin for Plack to perform WebID authentication on HTTPS connections; and Web::ID::Certificate::Generator, a module that allows you to generate WebID-enabled certificates that can be installed into web browsers.

Constructor

new

Standard Moose-style constructor.

Attributes

certificate

A Web::ID::Certificate object representing and x509 certificate, though a PEM-encoded string will be coerced.

This is usually the only attribute you want to pass to the constructor. Allow the others to be built automatically.

first_valid_san

Probably fairly uninteresting. This is the first subjectAltName value found in the certificate that could be successfully authenticated using Web::ID. An Web::ID::SAN object.

uri

The URI associated with the first valid SAN. A URI object.

This is a URI you can use to identify the person, organisation or robotic poodle holding the certificate.

profile

Data about the certificate holder. An RDF::Trine::Model object. Their FOAF file (probably).

valid

Boolean.

Methods

node

Returns the same as uri, but as an RDF::Trine::Node object.

get(@predicates)

Queries the profile for triples of the form:

  $self->node $predicate $x .

And returns literal and URI values for $x, as strings.

$predicate should be an RDF::Trine::Node, or a string. If a string, it will be expanded using RDF::Trine::NamespaceMap, so you can do stuff like:

  my $name   = $webid->get('foaf:name', 'rdfs:label');
  my @mboxes = $webid->get('foaf:mbox');

BUGS

Web::ID::Certificate, Plack::Middleware::Auth::WebID.

RDF::ACL provides an access control system that complements WebID.

CGI::Auth::FOAF_SSL is the spiritual ancestor of this module though they share very little code, and have quite different APIs.

THANKS

Thanks to Kjetil Kjernsmo (cpan:KJETILK) for persuading me to port my old CGI-specific implementaton of this to Plack.

Thanks Kjetil Kjernsmo (again), Florian Ragwitz (cpan:FLORA), and Jonas Smedegaard for help with testing and advice on dependencies.

Thanks to Henry Story, Melvin Carvalho, Simon Reinhardt, Bruno Harbulot, Ian Jacobi and many others for developing WebID from a poorly thought out idea to a clever, yet simple and practical authentication protocol.

Thanks to Gregory Williams (cpan:GWILLIAMS), Tatsuhiko Miyagawa (cpan:MIYAGAWA) and the Moose Cabal for providing really good platforms (RDF::Trine, Plack and Moose respectively) to build this on.
