1) What is the user liking
Based off of the most popular categories for Facebook Pages.
▪ Activities
▪ Businesses
▪ Groups
▪ Organizations
▪ People
▪ Places
▪ Products and Entertainment
▪ Websites
2) A clean page title
Search Engine Optimization has caused all sorts of stuff to
be crammed into the <title> tag.
▪ “The Semantic Web & THE POWER OF PULL | Blog Archive | The Facebook
Open Graph, Part I”
▪ “A New Data Model – Facebook Developer Blog”
▪ “W3C Track @ WWW2010, Raleigh, NC, USA ; 29-30 April 2010”
▪ “Open Graph Protocol | Google Groups”
4) A canonical URL
We wanted to use link-rel canonical.
▪ Major publishers were concerned that adding link-rel canonical would
negatively impact their ranking within search engines.
A simple example
What’s desired?
5 A short description
7 Location information
8 Contact information
5) A short description
A simple schema.
▪ Not respecting Don’t Repeat Yourself.
▪ Optimized for a consistent schema versus reuse of existing meta tags.
▪ One namespace. One prefix.
▪ One HTML tag attribute (“property”)
What we didn’t want
But tried.
Too complex!
7) Location information
▪ Couldn’t find a – simple – location markup specification.
▪ Reused the property names from the Microformat hCard
▪ Fully expect this information to be expressed within the page body
versus the head.
▪ RDFa gives us a consistent syntax for both cases.
