Connecting Plasma to service-oriented programming with JOLIE

Speaker: Fabrizio Montesi

Today, Plasma provides the means for presentation and data de-coupling, under the form of plasmoids and data engines. Applications can already share information by means of D-Bus, giving the feeling of a harmonic desktop workspace.

This harmony is not present at the network level, where applications often rely on ad hoc communication mechanisms. Service-oriented Computing (SOC) is a solution, but how can we bring it to Plasma?

In this presentation we will see how we can use JOLIE, a language born from the academic SOC research, for allowing Plasma to communicate with web services transparently. A joint work of the Plasma and JOLIE teams, the Plasma::Service <-> JOLIE MetaService architecture enables Plasma to exploit SOC in an elegant and abstract way, independently from the underlying communication mechanisms. As a case study, we will analyze an example for a distributed presentation viewing system.
