A developing paradigm in the area of Software Engineering is that of Model Driven Development where models are used to express operations that are thereafter interpreted and executed through the use of an execution engine. The high level of abstraction within these models present inherent challenges in guaranteeing operation that respect policies and other constraints during execution. Additionally, the domain specificity necessarily present within these execution engines make them rigid and not suited for repurposing across different domains. We propose to address these issues through the use of a middleware architecture that is responsible for the service delivery aspect of the execution engine. Our architecture will provide a separation of domain specific and domain independent concerns, resulting in a set of domain specific artifacts which possess domain knowledge, and a generalized execution platform that inherits its operations from the domain artifacts. Our design facilitates the realization of user intent through the generation, validation and execution of adaptation models at runtime constrained by policies. We show the viability of this approach in the User-Centric Communication Middleware, a layer of the Communication Virtual Machine, which is responsible for enforcing communication requirements.

“…user or management) models from detailed ones (e.g. software models), as is the case with, for example, the Workflow Communication Modeling Language WF-CML [59] in its definition of communication-specific abstractions of workflows concepts. An analogous problem results from the poor interweaving of different BPMN diagram types, in particular that no consistency criteria are imposed for them, for example collaboration versus choreography versus process diagrams.…”

We investigate three approaches describing models of business processes: the OMG standard BPMN in its recent version 2.0, the workflow patterns of the Workflow Pattern Initiative and their reference implementation YAWL. We show how the three approaches fail to provide practitioners with a suitable means precisely and faithfully to capture business scenarios and to analyze, communicate and manage the resulting models. On the positive side, we distill from the discussion six criteria which can help to recognize practical and reliable tool-supported business process description and modeling systems.

“…To date in our research group there has been one i-DMSL and DSVM that has been completely developed, CML [65] and CVM [19], respectively. Currently there is another i-DSML and DSVM for the microgrid energy management domain under development by Allison et al [2,3], Microgrid Modeling Language (MGridML), and Microgrid Virtual Machine (MGridVM), respectively.…”

“…CVM provides a runtime environment for the modeling and realization of user-centric communication services (see Figure 2.3). Models are specified using CML, which contain representations of concepts relevant in the user-centric communication domain [65]. we utilize the Event Condition Action (ECA) policy model [49], where events are control script commands being realized or events from the underlying layer being responded to, conditions are state information retrievable directly from the middleware or through an external monitor, and actions are accompanying actions that must be performed when realizing the initially requested command or the action association with the event being responded to.…”

A Middleware to Support Services Delivery in a Domain-Specific Virtual Machine

The increasing use of model-driven software development has renewed emphasis on using domain-specific models during application development. More specifically, there has been emphasis on using domain-specific modeling languages (DSMLs) to capture user-specified requirements when creating applications. The current approach to realizing these applications is to translate DSML models into source code using several model-to-model and model-to-code transformations. This approach is still dependent on the underlying source code representation and only raises the level of abstraction during development. Experience has shown that developers will many times be required to manually modify the generated source code, which can be error-prone and time consuming.An alternative to the aforementioned approach involves using an interpreted domain-specific modeling language (i-DSML) whose models can be directly executed using a Domain Specific Virtual Machine (DSVM). Direct execution of i-DSML models require a semantically rich platform that reduces the gap between the application models and the underlying services required to realize the application. One layer in this platform is the domain-specific middleware that is responsible for the management and delivery of services in the specific domain.In this dissertation, we investigated the problem of designing the domain-specific middleware of the DSVM to facilitate the bifurcation of the semantics of the dovi main and the model of execution (MoE) while supporting runtime adaptation and validation. We approached our investigation by seeking solutions to the following sub-problems: (1) How can the domain-specific knowledge (DSK) semantics be separated from the MoE for a given domain? (2) How do we define a generic model of execution (GMoE) of the middleware so that it is adaptable and realizes DSK operations to support delivery of services? (3) How do we validate the realization of DSK operations at runtime?Our research into the domain-specific middleware was done using an i-DSML for the user-centric communication domain, Communication Modeling Language (CML), and for microgrid energy management domain, Microgrid Modeling Language (MGridML). We have successfully developed a methodology to separate the DSK and GMoE of the middleware of a DSVM that supports specialization for a given domain, and is able to perform adaptation and validation at runtime.
