From 2009 to 2013 I worked as software engineer, lead software architect at Abril in the team that built this platform, we were a team of approximately 40 software engineers.
Abril Mídia is one of the largest media companies in Brazil. In 2011 it published 52 titles and is a leader in 22 out of 26 segments in which it operates. In the digital world, the big challenge Abril faces is deliver a large volume of information that it generates in a high diversity of digital channels, such as websites, mobile sites and TVs. The chosen solution was the building of a distributed platform, named Alexandria, that allows the content to be added and handled by separated information domains, implemented with REST constraints and with a hypermedia API, that is exposed to publishers and end users.
The result of this work became a paper published by Springer in the book "Rest: Advanced Research Topics and Practical Applications" and it was written by Luiz Rocha and me.
I spoke in QCon Conference São Paulo in 2012 about all the technical aspects of Alexandria, you can find links to slides and talk below (in Portuguese).
