Before we dive into this...

Jaggeree

History lesson

Jaggeree

Facebook Connect is 2 years old this year... although Connect is now Facebook for Websites

What sort of things can you make?

Jaggeree

WISHYMOM/

Why are we doing stuff with Connect/Facebook for Websites...

All about users, and lots of them. Not just users, but people who have curated “real”
identities. Solves a major problem which is that the data you get in from registration forms is
often useless. The most common ZIP codes in US data are 12345 and 90210 which means a
larger than expected number of people from Schenectedy and Beverly Hills

There’s also an over representation of Afghanistan.

Second reason for using something like connect is social proof.

It’s always more tempting to eat at a restaurant with a queue, rather than an empty one.
Especially if that queue contains our friends or people we know of and trust

Connect surfaces activity constantly in newsfeeds and activity streams, we can harness that
for our apps

Jaggeree

So, what is it?

At it’s basis, it’s a method for logging into Facebook and sharing the success of the login
with the site supporting Connect.

Jaggeree

It’s more than that though as it gives you an access token which allows you to do more such
as post things to the newsfeed

Jaggeree

like this...

Jaggeree

One nice thing about Connect is that it can all be prototyped client side and if your page
markup is clean and semantic, you can prototype or power live implementations just using
the Connect libraries, your existing markup and something like JQuery

Jaggeree

There also used to be things like fan boxes that you could embed into your pages.

JAGGEREE/

Then the world changed a bit last week in San Francisco at F8

FACTORYJOE/

Jaggeree

Chris Messina of Google summed it up quite well with this bit of Photoshop trickery.
Facebook made something which suggested that all roads on the web led to them.

JAGGEREE/

Jaggeree

They launched something called Open Graph, where it was a mixture of the content graphs
within websites which are often at best hidden and at worst absent and the social graph,
creating an interest graph.

Jaggeree

This new focus is clear on the developer homepage, with the focus being on Add Facebook to
my site

Jaggeree

And connect is now relaunched as Facebook for websites

Jaggeree

So what is this Open Graph and where will we most likely see it...

There are a collection of simple social plugins, the one you’re most like to see or implement
is called Like which is a button which is accompanied by something

Jaggeree

called the Open Graph Protocol, a standard being proposed by Facebook which for the ﬁrst
time brings a proposal for simple semantic metadata that describes pages in a standardised
format

Jaggeree

here’s a chunk of Open Graph metadata

Jaggeree

The good news is that on the whole, it’s not just Facebook that can read the metadata. Here
I’ve built a tiny app which essentially reads the meta tags and acts as a sort of generic
metadata API

Jaggeree

There’s also a social plugin called the like box which is the new replacement for the Fan box

Jaggeree

And there’s a version of the Like control which allows you to add comments. This is useful for
situations such as one where there is an article decrying the election of someone from the
BNP being elected somewhere and allows you to provide your context around a headline such
as “BNP wins seat in election” rather than just saying you like it.

Not all publishers as we saw in the Huffington Post example provide a description text.

Jaggeree

There are also activity and recommendation boxed which are powered from shares and likes.
These are things you can place on your site

Jaggeree

For instance you can show most recent activity. Since many of the new Facebook for Websites
controls can display information about a user’s social and interest graph just from the
presence of a Facebook cookie, rather than people declaratively logging in this gives instant
personalisation

Jaggeree

There’s also a recommendations box which is the longer term version of the activity box.
This is about likes over all time.

Jaggeree

So how would you get all those lovely users and their details to use. This is a lot of the old
Facebook Connect type stuff in here, it’s pretty much a drop in replacement apart from a
slightly different structure to the Javascript.

Jaggeree

Here’s a chunk of PHP showing how you can hook the Facebook cookie for your site out and
use the IDs and access tokens contained within them to get more information about the
logged in user.

Jaggeree

One useful social proof style mechanism is to use the Login with Faces control. This takes the
login button and shows you pictures of friends who already use the service.

Jaggeree

Or you can use a facepile which does a similar thing without the login button.

Jaggeree

When you perform the login, instead of the complicated assent form with a mix of
permissions you now have a simple one size ﬁts all request for permission box. This makes it
far easier for the developer who now doesn’t have to have all sorts of fallback methods for
people who don’t want to share speciﬁc permissions. The downside is people who don’t want
to give those permissions will just not hit Allow.

Jaggeree

One things that has been talked about a lot is using the users existing social graph to
personalise the site, pulling together lists of content such as music tracks your friends like
within the core of your site. You’ve been able to do this for a while now, so this isn’t really
anything new.

Jaggeree

one other control which may be of some use to those of you working with live events and
media is the live stream. this is being heavily used in the run up to the General Election.

Jaggeree

Measurement and analytics of all of this is very possible, here’s some sample graphs from
Insight. The lower one shows activity from Connect methods (feed story publication and
interaction with it after being published)

Jaggeree

Here’s an example of a Graph API call for the likes of a page from the Washington Post,
showing the Open Graph information about the story and the information about the likes
(still logged as fan count).

Jaggeree

Here’s a similar Graph API query for a page in The Guardian which shows the likes/shares...

These sorts of queries can be very useful for building counters of popularity for your content.

Some publishers block this information though unless you are authenticated.

Jaggeree

So what have people done with these news APIs so far

Jaggeree

This is an example from Time magazine with the recommendations box

Jaggeree

and a like button integrated within a social distribution panel

Jaggeree

this was a lovely thing I found

http://likebutton.me/

Jaggeree

One big change to the Connect and the generic APIs is that you can now cache data fro
greater than 24 hours. This is a major bonus to publishers. This information can be kept up
to date by subscribing for speciﬁc updates which are then posted to you using a webhooks
compliant mechanism

Jaggeree

So, what about things other than websites. Well you can do connect on Desktop clients and
Adobe Air and Flash/Flex apps

Let’s talk for a little while about one really important aspect which is Connect for phones, or
what is now Facebook for Mobiles.

This is an example of a Playﬁsh game as an iPhone app with Facebook Connect to allow you
to compete against your friends and reconcile your mobile scores in online score tables.

Jaggeree

There’s a client library for Facebook for the iPhone which you can use from Objective C in
XCode

Jaggeree

There’s also a development environment for the iPhone called PhoneGap which allows you to
make iPhone apps, either as prototypes or the real things using HTML, Javascript and CSS,
compiling them in to a native app and giving you access to the underlying APIs of the phone.

Jaggeree

People have now built ways that you can use the Facebook library for the iPhone from within
PhoneGap.

Jaggeree

Another lightweight app development environment that can build cross platform apps is
Titanium Developer which uses native Javascript APIs as a domain speciﬁc language which is
cross compiled to a Native App. It’s currently slightly unclear whether this breaks terms of
service for iPhone OS4. However it’s a very impressive way of making apps quickly.

Jaggeree

And it has a set of libraries speciﬁcally for Facebook

Jaggeree

Finally there is a community contributed port of the Connect for iPhone to the Android
platform. In addition there are native web clients which use the conventional Facebook for
Websites controls.

JAGGEREE/

Jaggeree

One more thing. We’ve talked about Facebook extending into the wider web. It’s clear they’re
also interested in the physical world. There is talk of them buying Foursquare and also of
having their own geoplatform. One interesting thing at F8 was the small RFID chips they gave
every attendee to checkin at sessions...

JAGGEREE/

Jaggeree

Which would allow status updates and an automated Like of a session. Imagine if they could
bring this into the real world...

@anywhere from Twitter

Jaggeree

What else is there out there, well there are distributed identity plays such as JanRain’s RPX
and Google Friend Connect which allow you to use different forms of identity such as
MySpaceID, Yahoo logins, OpenID and Gmail accounts to name a few to login.

There’s also the recently released (week before F8) @anywhere from Twitter

Jaggeree

Which allows you to login to apps using your Twitter credentials

Jaggeree

and those applications can do Graph API like queries to ﬁnd out more about users using
simple JavaScript controls like hover cards, follow and retweet buttons

Jaggeree

and allow you to post messages from deep within sites you’ve connected with

Jaggeree

you can read a bit about some prototypes of this we made at The Guardian.

Get users quick
Social proof of user actions
Social sharing of content
Social augmentation/personalisation of content
Can now cache data for more than 24 hours

Jaggeree

So why do this...
