The growing popularity of public APIs and technologies such as web hooks is changing online services drastically. It is easier now than ever to interconnect services and access them as a third party. The next logical step is to use intelligent agents to provide a better user experience across services, connecting services with smart automatic behaviors or actions. In other words, it is time to start using agents in the so-called Evented Web. For this to happen, agent platforms need to seamlessly integrate external sources such as web services. As a solution, this paper introduces an event-based architecture for agent systems. This architecture has been designed in accordance with the new tendencies in web programming and with a Linked Data approach. The use of Linked Data and a specific vocabulary for events allows a smarter and more complex use of events. Two use cases have been implemented to illustrate the validity and usefulness of the architecture.
