Abstract

A framework is proposed for assembling software systems from distributed heterogeneous components. For the successful deployment of such a software system, it is necessary that its realization not only meet the functional requirements, but also non-functional requirements such as Quality of Service (QoS) criteria. The approach involves: a) the creation of a meta-model for components, called the Unified Meta Model (UMM), and an associated hierarchical format for indicating the contracts and constraints of the components, b) resource discovery components, called "headhunters," that locate components according to a software developer's request, c)
automatic generation of glue and wrappers, based on a designer's specifications, for achieving interoperability, d) guidelines for specifying and verifying the quality of components and their compositions, e) a formal mechanism for precisely describing the meta-model, f) a methodology for component-based software design, and g) validation of this framework by creating proof-of-concept prototypes. A formal specification based on Two-Level Grammar is used to represent these notions in a tightly integrated way so that QoS becomes a part of generative domain models.
