“Default is social”, notes from the f8, FaceBook conference

Policy changes:

Single permissions dialog
Data retention policy changes

Platform changes:

1. Social Plug-ins (tested on this blog)

o a way to provide personalized experience with “Like” button in the core, work on any site
o works via iframe, single line of HTML code
o activity stream plug-in (newsfeed filtered for events only related to the site)
o recommendations plug-in, personalized recommendation experience for users about any product or service
o log-in plug-in that shows friends who are already there
o FB chat plug-in
o “Like” button in the center with hope to serve 1 Billion “likes” within 24 hrs after roll-out

2. Open Graph protocol

o Semantic markers (my understanding is that is another name for microformats)
o Design to represent any object on the web – books, celebrates, movies, etc
o Objects has the same properties as FB pages

3. Graph API

o Complete re-architecture of current platform/API/SDK
o No need for SDK code
o Graph.facebook.com/ID/connection_name – is a universal way to access/search for objects, people, or connections
o RealTime callbacks (WOW! Finally! App will be notified what users do/change/ when they do that)
o OAUTH (2.0) (like it!)

Facebook Friends Connect

Is a way to extend external sites to provide: FB identity FB friends (relationship) Feed to FB Demo app at http://www.somethingtoputhere.com/therunaround User experience: login: js login method requiresession(): detects state of usr-FB relationship, log-in into FB if needed.

Posting to FaceBook feed using Graph API

Graph API was announced at F8 with a promise to dramatically simplify the FB API. I checked the read access over the new interface during the presentations and to my big surprise it worked flawlessly and from the first time. When I tried https://graph.facebook.com/facebook , JSON-formatted info about the FaceBook page was returned (as expected). Then I tried OAuth 2.0 way of accessing the API to post a message to the feed. And to my even bigger surprise it worked too! Here is what you need to do to access Graph API over OAuth: 1. Create a FB app, store app properties to a file: $appkey = '7925873fbfb5347e571744515a9d2804' ; $appsecret = 'THE SECRET' ; $canvas = 'http://apps.facebook.com/graphapi/' ; 2. Create a page that will prompt user the access permission (I am prompting for the publish_stream and offline_access permissions at the same time) //http://apps.facebook.com/graphapi/ require 'settings.php' ; $url = "https://graph.face

Ripple Baby Steps
