The CHOReOS development process reported in this document capitalizes on previous work by the CHOReOS team described in the previous deliverable D2.1. The latter described the CHOReOS software development process by defining the main activities that need to be performed and the artifacts manipulated by these activities without referring to specific technologies, tools, standards, models, etc. This deliverable concretely defines the specific process activities (and their data flow in term of manipulated I/O artifacts) we are implementing to develop CHOReOS choreographies by conforming to the CHOReOS development process model presented in D2.1. In particular, we clearly and concisely specify what standards, notations, languages, technologies and tools we are using to implement the process activities that will be then integrated by the CHOReOS Integrated Development and Run-time Environment (IDRE) being developed in WP5. Furthermore, accounting for the review recommendations, we clarify QoS and data aspects, further defining ULS dimensions and their relationships with the development process activities and CHOReOS case-studies.
