Domain Objects and Microservices for Systems Development: a roadmap

This paper discusses a roadmap to investigate Domain Objects being an adequate formalism to capture the peculiarity of microservice architecture, and to support Software development since the early stages. It provides a survey of both Microservices and Domain Objects, and it discusses plans and reflections on how to investigate whether a modeling approach suited to adaptable service-based components can also be applied with success to the microservice scenario

What’s in an Agreement? An Analysis and an Extension of WS-Agreement

Non-functional properties of services and service compositions are of paramount importance for the success of web services. The negotiation of non-functional properties between web service provider and consumer can be agreed a priori by specifying an agreement. WS-Agreement is a recently proposed and emerging protocol for the specification of agreements in the context of web services. Though, WS-Agreement only specifies the XML syntax and the intended meaning of each tag, which naturally leads to posing the question of “What’s in an Agreement?” We answer this question by providing a formal definition of an agreement and analyzing the possible evolution of agreements and their terms. From our analysis we identify ways in which to make an agreement more robust and long lived by proposing two extensions to the specification and supporting environment
