OpenID 3.0, XRDS-Simple and Portable Contacts

[Pfefferle]

Based on the "OpenID Relying Party with Portable Contacts Demo" by
JanRain (http://portablecontactsdemo.janrain.com/) I've hacked
together a little Portable Contacts Delegation plugin. To run the Demo
(http://portablecontactsdemo.janrain.com/) with your WordPress
installation, you also need the OpenID 3.0 and XRDS-Simple 1.0
WordPress Plugin.

You can try the code here: http://notizblog.org/wp-content/uploads/portablecontacts_0.1.zip

I have also extended http://OpenID.org so that it also works with your demo
for all users registered.

Works very nicely :) Great sample.

Now we just need to turn your blog into a Portable Contacts provider....!

Anyone?

FYI, for info on implementing support for PoCo, check out Plaxo's documentation:

http://www.plaxo.com/api/portablecontacts

We could literally reuse all the data from the Friends plugin... and the Extended Profile plugin. Since PoCo is based on vcard, it shouldn't be hard to make this happen.

Was confused by the "OpenID 3.0" until I realized you meant the OpenID
plugin for WordPress version 3.0, not protocol version. :)

That's correct. Thought imaging OpenID 3.0 would be rather interesting... clearly it'd start by merging in a finalized version of the OAuth-OpenID extension:

Sorry for the confusing headline :)

If no one else, I am very interested in working on a fully featured
portable contacts provider/client for wordpress.

I wonder if it’s possible to work on a full featured provider for a
vanilla LAMP stack? Beyond that, I'm also interested in building a
WordPress portable contacts client.

Totally. I think that's kind of what Shindig is... but focusing on basic services -- and on interop and service discovery would be awesome.

I can imagine being able to spin up your own contact server that you simply point to from your XRDS-Simple profile -- completely self-contained -- so we can continue to rev it as it's own project -- meanwhile leveraging people's contacts as they store them in their personal Highrise-like store.

Also, this tool might be of some interest -- I should ping the developer and see if he'd be able to make this tool act as a local server that would be able to act as a PoCo front end to the Apple Address Book for local testing:

I never saw Shindig before. Looks interesting—and it has the REST API
baked in. And since you can run it on PHP, maybe the service discovery
part could be ported from the WordPress plugin? Not experienced in
this at all, so I’m just wondering.

The benefit of running your own contact server is not limited to
ownership of data, but also the ability to update the information
within rapidly + dynamically (either using a plugin, or as a built-in
feature.)

A hypothetical use case: I may be on Twitter, Plurk, Jaiku, Pownce,
and fifty other social networks—but which one is the *best* way to
contact me? I built a quick and dirty diagram explaining how one might
do this:

I’m working on providing something like this on my blog, Unfortunately functional oAuth support on .Net is limited (some libraries but they are only partially finished) so I am having to start from there. I hope to have something this weekend.

[Chris Messina]

Yeah, that's kind of what we call the "message broker" or "contact broker" -- very similar to what's built into Cisco phone networks, where, based on a number of factors, your phone number follows you from your cell phone to your office line to your home phone, depending on where you are.

You could imagine the same kind of thing based on where you've recently checked in.

What we're really talking about, though, is presence, and that's a slightly different surface of the same problem/opportunity space.

We couldn't use rel-contact, since that's reserved in XFN (though HTML5 apparently was going to use rel-contact for contact information for the current page -- similar to your "rel-reachme" idea). This may be a moot issue if we're able to indicate to a parser or consumer that the information provided is current and will expire in, say, a couple hours... that way whatever information is on your profile is the most up to date and most accurate (another argument for decentralization over data hoarding).

Chris

In this case, running my own personal contact server means that I can
rapidly feed and update the "I am best reached at..." information. So,
if I stopped being on Twitter and start on Plurk, my personal identity
page would be updated to reflect that.

Usually "best reached at" is *highly* dependant on what your are trying
to communicate and why.

Started to get an error on this now (few people tried it successfully last
week).
