This paper develops a Rewriting Logic framework for the automatic specification and verification of Web applications that considers the critical aspects of concurrent Web interactions, browser navigation features (e.g., forward/backward navigation, page refresh, and new window/tab opening), and Web script evaluation. By encompassing the main features of the most popular Web scripting languages (e.g., PHP, ASP, and Java Servlets), our scripting language is powerful enough to model the dynamics of complex Web applications, where the interactions among Web servers and Web browsers are formalized through a landmark communicating protocol that abstracts HTTP. We provide a detailed characterization of browser actions via rewrite rules and show how our models can be naturally model-checked by using the Linear Temporal Logic of Rewriting (LTLR), which is a Linear Temporal Logic that is specifically designed for model-checking rewrite theories. The framework has been completely implemented in Maude, and we report on some successful experiments that we conducted using the Maude LTLR model-checker.

In the distributed development of modern IT systems, contracts play a vital role in ensuring interoperability of components and adherence to specifications. The design of embedded systems, however, is made more complex by the heterogeneous nature of components, which are often described using different models and interaction mechanisms. Composing such components is generally not well-defined, making design and verification difficult. Several denotational frameworks have been proposed to handle heterogeneity using a variety of approaches. However, the application of heterogeneous modeling frameworks to contract-based design has not yet been investigated.In this work, we develop an operational model with precise heterogeneous denotational semantics, based on tag machines, that can represent heterogeneous composition, and provide conditions under which composition can be captured soundly and completely. The operational framework is implemented in a prototype tool which we use for experimental evaluation. We then construct a full contract model and introduce heterogeneous composition, refinement, dominance, and compatibility between contracts, altogether enabling a formalized and rigorous design process for heterogeneous systems. Besides, we also develop a generic algebraic method to synthesize or refine a set of contracts so that their composition satisfies a given contract.

“…In particular, all aspects of concurrent and real-time behaviour which are relevant to the system being developed must be accurately described and preserved through model transformations. To this end, the use of a meta-model based on the Ravenscar profile [1] has proven to be a very useful concept, enabling static timing analysis methods to be applied to high-level system models [4] In this paper, we describe an architecture that eases the automatic development of High-integrity Distributed Real-Time (HDRT) systems from their design to their implementation and schedulability analysis. The approach adapts and integrates a set of timing analysis tools into an MDE toolset for hard real-time systems.…”

Building High-integrity Distributed Real-Time (HDRT) systems requires a rigorous methodology to assist in the design and development of verifiable software. This paper describes an approach based on the Model-Driven Engineering (MDE) paradigm to ease the automatic generation of HDRT applications from high-level system models. Since those applications must be amenable to stringent timing analysis, such as the determination of worst-case execution time or schedulability analysis, we present the integration of a set of timing analysis tools with a toolset for MDE. In addition, this paper explores a new approach to integrating the real-time endto-end flow model with the automatic generation of Ravenscarcompliant source code in distribution middleware.
