Young risk taker.: [ruby] myOpenID and OpenID Attributes Exchange, myOpenID isn't supported Type URI described in http://axschema.org/

JanRain's myOpenID is popular OpenID provider, supports SSL, SREG, some persona, authentication with Information Card, OpenID Attributes Exchange (but only some attributes), Pavatar and so on. JanRain also offers ruby-openid that implements OpenID 2.0 with Ruby.

myOpenID supports only some attributes that can be exchange with OpenID Attribute Exchange, but you should care about Type URI, because myOpenID doesn't support Type URI described on "http://www.axschema.org/types/". You should specify Type URI with "http://schema.openid.net/" instead.

Sample code that fetch some attributes from myOpenID is as follows. At first, you need to initialize your persona. My persona for work is "Rakuto Furutani".

ConsumerController#start in /path/to/rails_openid/app/controller/consumer_controller.rb

ax_req     = OpenID::AX::FetchRequest.new
requested_attrs = [ ['http://schema.openid.net/namePerson', 'name', true],
                   ['http://schema.openid.net/namePerson/friendly', 'nickname'],
                   ['http://schema.openid.net/contact/email', 'email', true],
                   ['http://schema.openid.net/contact/web/default', 'web_default'],

                   ['http://schema.openid.net/pref/language', 'language']]

requested_attrs.each {|a| ax_req.add(OpenID::AX::AttrInfo.new(a[0], a[1], a[2] || false))}
oidreq.add_extension(ax_req)
oidreq.return_to_args['did_ax'] = 'y'
pp oidreq
end

Conclusion about myOpenID

Supports only some attributes that can be exchanged with AX.
Doesn't support openid.ax.update_url yet.
Doesn't support Type URI described in axschema, you should specify Type URI with "http://schema.openid.net/" namespace.
