DESCRIPTION
Facebook recently launched the Open Graph API, a bundle of plugins that defines social relationships between objects (movies, music and activities) and the Facebook user profile. Finally, the semantic web becomes mainstream. How open is the Open Graph API? What are the alternatives? What are the implications for privacy and what new, innovative services enabled by semantic metadata web linking will become possible.TRANSCRIPT

adding semantics =
adding meaning
Friday 21 May 2010
the RDF way
Friday 21 May 2010
RDF is a triple model i.e. every piece of knowledge is broken down into ( subject , predicate , object )

de portables has for listener Hendrik
Friday 21 May 2010
(de portables, listener, Hendrik)

in RDF the atoms of knowledge are triples of the
form (subject,predicate,object)

When all likes lead to Facebook, and liking requires a Facebook account, and Facebook gets to hoard all of the metadata and likes around the interactions between people and content, it depletes the ecosystem of potential and chaos — those attributes which make the technology industry so interesting and competitive. It’s one thing for semantic and identity layers to emerge on the web, but it’s something else entirely for the all of the interactions on those layers to be piped through a single provider (and not just because that provider becomes a single point of failure).

a massive personalized recommendation systemwith a lot of target ads

“Authenticated Pagerank”
Friday 21 May 2010
This sounds a lot to me like “Authenticated PageRank” — where everyone that wants to be listed in the index would have to get a Google account first. Sounds kind of smart, right? Except — shucks — there’s just one problem with this model: it’s evil!

The Huffington Post actually compared Facebook’s privacy issues to the BP oil spill. Shameful.
