We presented Battlefield REST at API Days Mediterranea 2014 held in Barcelona. The purpose that we seeked with this talk was to show our internal thinking process: Starting with why we chose to focus on APIs, why we selected the technology stack we did and the technical decisions we have made at the implementation levels and how these are hindering or boosting our ability to meet our goals. I must confess I prepared a 1 hour talk, enough to discuss each point in detail. Eventually I only had 25 min to present, so I left many topics that I’d like to have discussed aside. In any case, my fault. During the following days, I’ll be posting articles in english diving in all the topics of the presentation. I hope this server to redeem my sin.
