How would you feel playing Pacman on a single, straight line of dots ?

Boring,right ?

Multichannel content distribution is the real Pacman

21/05/2011Nicolas Pastorino - DPC11

Pre-requisites to multichannel distribution

Separation of layout and content at the content source level

Do not compromise on user experience 2

“The Superman Effect” Aral Balkan, DPC11

“There is a lot of effort going into improving customer experience. It is key to get consistency across different channels so their experience does not vary” Jim Daviesni

Have a single source of content 3

“Publishers usually can't afford a dedicated editorial team per channel”

"Multichannel media consumers have higher levels of engagement than those present in only one channel.

The more one watches TV, listens to the radio, spends time online, etc., the more advertising they consume.

This shows that multichannel content distribution will also have an important impact on the publishers revenue structure. It will evolve to become a competitive, critical, enabling technology for marketing communications."

Having a REST ?

A touch more of

insight will help...

“Media companies as well as consumer brands must recognize that adding mobile to the multichannel mix does not mean creating a mini-channel. Those building mobile strategies should recognize that:

• Mobile is not just about shrinking the desktop experience,

• The user environment is an element of the mobile experience,

• Mobile users are not simply a subset of online users – some are new.”

REpresentational State Transfer

REST is a set of principles that define how Web standards, such as HTTP and URIs, are supposed to be used.

• Give every “thing” an ID• Link things together• Use standard methods• Resources with multiple representations• Communicate statelessly

Key goals of REST include:

• Scalability of component interactions• Generality of interfaces• Independent deployment of components• Intermediary components to reduce latency, enforce security and encapsulate legacy systems

// ezpRestVersionedRoute( $route, $version ) // $version == 1 should be the same as if the only the $route had been present new ezpRestVersionedRoute( new ezpMvcRailsRoute( '/foo', 'myController', 'myActionOne' ), 1 ), new ezpRestVersionedRoute( new ezpMvcRailsRoute( '/foo', 'myController', 'myActionOneBetter' ), 2 ),
