Web::ID - implementation of WebID (a.k.a. FOAF+SSL)
my $webid = Web::ID->new(certificate => $pem_encoded_x509); if ($webid->valid) { say "Authenticated as: ", $webid->uri; }
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.
new
Standard Moose-style constructor.
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.
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:
$predicate
my $name = $webid->get('foaf:name', 'rdfs:label'); my @mboxes = $webid->get('foaf:mbox');

Web::ID::FAQ.
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 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.
