The document discusses Facebook's APIs for accessing user data and social graph information. It explains that applications need an OAuth access token to access basic user profile data or more data with explicit permissions. It also describes Facebook Query Language (FQL) and the Open Graph Protocol (OGP) for querying social graph data through the Graph API by injecting RDFa metadata onto web pages to represent them as graph objects.

• Applications can only access some basic data from
user profiles - such as name, gender, and profile
picture - and explicit permissions must be granted to
access additional data.

APIs
• Facebook Query Language
• Open Graph Potocol
• Make any web page an object in a rich social
graph by injection some RDFa metadata into the
page, and the Graph API is a simple and instuitive
mechanism for querying the graph.

data with FQL
• More advanced types of queries or certain
workflows, You can use FQL to be a better fit for the
problem.
