 | Component-based software engineering provides developers the opportunity to assemble entire systems from components. When applied to Distributed Real-Time and Embedded (DRE) systems, which components to assemble and how to assemble them are determined not only from functional correctness criteria but also assurance of the system's quality of service (QoS). This paper presents a grammatical QoS-driven approach to optimizing component assembly by reducing the search space of assembly alternatives through the ... |

| Software systems are usually designed and documented with the aid of visual modeling notations. Visual modeling notations keep evolving over the years in tandem with visual modeling tools, and the tight binding in between impedes the exchanging of modeling assets, which causes a spatial isolation of the models. Another problem with legacy software models is that they are isolated temporally in the early phases of the software engineering life cycle ... |

|
| We present an approach towards automatic component assembly based on aspect-oriented generative domain modeling. It involves the lifecycle covering the component specification generation, and subsequent assembly of implementation components to produce the final software system. Aspect-oriented techniques are applied to capture the crosscutting concerns that emerge during the assembly process. Subsequently, those concerns are woven to generate glue/wrapper code for assembling heterogeneous components to construct a single integrated system. |

|
| Web Services (WS) has emerged as a new component-based software development paradigm in a network-centric environment based on the Service Oriented Architecture (SOA), the open standard description language XML and transportation protocol HTML. Therefore, legacy software systems can incorporate WS technology in order to be reused and integrated in a distributed environment across heterogeneous platforms. While WS is gaining its momentum toward wide adoption in the software industry, there are ... |

| Component-based software composition offers a development paradigm with reduced time-to-market and cost while achieving enhanced productivity, quality and maintainability. Existent work on the composition paradigm are of a static composition paradigm, which is not sufficient in distributed environment, in which both constituent components and assembled distributed system are subject to dynamic adaptation. This paper presents two types of dynamic composition for distributed components: assertive and autonomous over .NET based Web ... |

| The advancement of internet technology enables legacy software systems to be reused across geographical boundaries. Web Services (WS) have emerged as a new component-based software development paradigm in a network-centric environment based on the Service Oriented Architecture (SOA), the open standard description language XML and transportation protocol HTML. Therefore, legacy software systems can incorporate WS technology in order to be reused and integrated in a distributed environment across heterogeneous platforms. ... |

| Web Services (WS) technology is becoming pervasive in the development of distributed systems and is an appealing vehicle for service presentation and horizontal integration. On the other hand, Model Integrated Computing (MIC) offers a means of system integration in the vertical direction by using domain-specific modeling, and then synthesizing the software system from the high-level model using a model-specific generator. This paper presents a meta-modeling approach to WS to explore ... |

| Feature modeling is a popular domain analysis method for describing the commonality and variability among the domain products. The current formalisms of feature modeling do not have enough support for automated domain product configuration and validation. We have developed a theory of feature modeling: a feature model is analogous to a definition of a language; a particular feature composition instance (domain product) is analogous to a program written in that ... |

| UniFrame is a framework to help organizations to build interoperable distributed computing systems. Using UniFrame, a new system is built by assembling predeveloped heterogeneous and distributed software components. UniFrame solves the heterogeneity problem by explicitly modeling the domain knowledge of various technology domains (component model domains, programming language domains, operating system platform domains, etc.), from which the Interoperation Generative Domain Model (IGDM) straddling the technology domains can be constructed. The ... |

| Component-Based Software Development (CBSD) offers a cost-effective means of software production with reduced time-to-market. Integration of heterogeneous components poses a non-trivial challenge in realizing this vision, which is further complicated in a distributed environment as a result of blurred functional and non-functional aspect representation and management. We propose a two-level approach, i.e., to apply aspect-oriented component modeling/specification to handle the problem. |

| The UniFrame approach to component-based software development assumes that concrete components are developed from a meta-model, called the Unified Meta-component Model, according to standardized domain models. Implicit in this development is the existence of a Platform In dependent Model (PIM) that is transformed into a Platform Specific Model (PSM) under the principles of Model-Driven Architecture (MDA). This position paper advocates natural language as the starting point for developing the meta-model ... |

| Feature modeling is commonly used to capture the commonalities and variabilities of systems in a domain during Domain Analysis. The outputs of feature modeling are reusable assets (i.e., components, patterns, domain-specific language, etc.) that can be fed into the application engineering phase for ultimate software products. But current practice lacks an automatic approach for seamless generation of reusable assets from feature models. This paper presents an algorithm for generating sets ... |

| Web Services offer a platform independent solution for system integration in a distributed environment. But Web Services are weak in representing the business semantics of application domains. This paper presents a model-driven approach for specifying domain-specific component models in an effort to complement the current Web Services technology in terms of enriching the semantics representation. Web Services Description Language (WSDL) can then be generated automatically from the models with generators. ... |
