Ontology-based patterns for the integration of business processes and enterprise application architectures
Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge
the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture
descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of
software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data.
Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an
ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their
applicability in business process-driven application integration is demonstrated
Heterogeneous component interactions: Sensors integration into multimedia applications
Resource-constrained embedded and mobile devices are becoming increasingly
common. Since few years, some mobile and ubiquitous devices such as wireless
sensor, able to be aware of their physical environment, appeared. Such devices
enable proposing applications which adapt to user's need according the context
evolution. It implies the collaboration of sensors and software components
which differ on their nature and their communication mechanisms. This paper
proposes a unified component model in order to easily design applications based
on software components and sensors without taking care of their nature. Then it
presents a state of the art of communication problems linked to heterogeneous
components and proposes an interaction mechanism which ensures information
exchanges between wireless sensors and software components
Quality-aware model-driven service engineering
Service engineering and service-oriented architecture as an integration and platform technology is a recent approach to software systems integration. Quality aspects
ranging from interoperability to maintainability to performance are of central importance for the integration of heterogeneous, distributed service-based systems. Architecture models can substantially influence quality attributes of the implemented software systems. Besides the benefits of explicit architectures on maintainability and reuse, architectural constraints such as styles, reference architectures and architectural patterns can influence observable software properties such as performance. Empirical performance evaluation is a process of measuring and evaluating the performance of implemented software. We present an approach for addressing the quality of services and service-based systems at the model-level in the context of model-driven service engineering. The focus on architecture-level models is a consequence of the black-box
character of services
Ontology-based modelling of architectural styles
The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as architectural styles, structural and behavioural modelling, into a coherent framework. Architectural styles are often neglected in software architectures. We propose an ontological approach for architectural style modelling based on description logic as an abstract, meta-level modelling instrument. We introduce a framework for style definition and style combination. The application of the
ontological framework in the form of an integration into existing architectural description notations is illustrated

Towards an aspect weaving BPEL engine
This position paper proposes the use of dynamic aspects and
the visitor design pattern to obtain a highly configurable and
extensible BPEL engine. Using these two techniques, the
core of this infrastructural software can be customised to
meet new requirements and add features such as debugging,
execution monitoring, or changing to another Web Service
selection policy. Additionally, it can easily be extended to
cope with customer-specific BPEL extensions. We propose
the use of dynamic aspects not only on the engine itself
but also on the workflow in order to tackle the problems of
Web Service hot deployment and hot fixes to long running
processes. In this way, composing aWeb Service "on-the-fly"
means weaving its choreography interface into the workflow
Pattern-based software architecture for service-oriented software systems
Service-oriented architecture is a recent conceptual framework for service-oriented software platforms. Architectures are of great importance for the evolution of
software systems. We present a modelling and transformation technique for service-centric distributed software systems. Architectural configurations, expressed through hierarchical architectural patterns, form the core of a specification and transformation technique. Patterns on different levels of abstraction form transformation invariants that structure and constrain the transformation
process. We explore the role that patterns can play in architecture transformations in terms of functional properties, but also non-functional quality aspects
MODEL DRIVEN SOFTWARE PRODUCT LINE ENGINEERING: SYSTEM VARIABILITY VIEW AND PROCESS IMPLICATIONS
La Ingeniería de Líneas de Productos Software -Software Product Line Engineerings
(SPLEs) en inglés- es una técnica de desarrollo de software que busca aplicar
los principios de la fabricación industrial para la obtención de aplicaciones informáticas:
esto es, una Línea de productos Software -Software Product Line (SPL)-
se emplea para producir una familia de productos con características comunes, cuyos
miembros, sin embargo, pueden tener características diferenciales. Identificar
a priori estas características comunes y diferenciales permite maximizar la reutilización,
reduciendo el tiempo y el coste del desarrollo. Describir estas relaciones
con la suficiente expresividad se vuelve un aspecto fundamental para conseguir el
éxito.
La Ingeniería Dirigida por Modelos -Model Driven Engineering (MDE) en
inglés- se ha revelado en los últimos años como un paradigma que permite tratar
con artefactos software con un alto nivel de abstracción de forma efectiva. Gracias
a ello, las SPLs puede aprovecharse en granmedida de los estándares y herramientas
que han surgido dentro de la comunidad de MDE.
No obstante, aún no se ha conseguido una buena integración entre SPLE y MDE,
y como consecuencia, los mecanismos para la gestión de la variabilidad no son suficientemente expresivos. De esta manera, no es posible integrar la variabilidad de
forma eficiente en procesos complejos de desarrollo de software donde las diferentes
vistas de un sistema, las transformaciones de modelos y la generación de código
juegan un papel fundamental.
Esta tesis presenta MULTIPLE, un marco de trabajo y una herramienta que persiguen
integrar de forma precisa y eficiente los mecanismos de gestión de variabilidad
propios de las SPLs dentro de los procesos de MDE. MULTIPLE proporciona
lenguajes específicos de dominio para especificar diferentes vistas de los sistemas
software. Entre ellas se hace especial hincapié en la vista de variabilidad ya que es
determinante para la especificación de SPLs.Gómez Llana, A. (2012). MODEL DRIVEN SOFTWARE PRODUCT LINE ENGINEERING: SYSTEM VARIABILITY VIEW AND PROCESS IMPLICATIONS [Tesis doctoral no publicada]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/15075Palanci
A SPEMOntology for Software Processes Reusing
Reusing the best practices and know-how capitalized from existing software process models is a promising solution to model high quality software processes. This paper presents a part of AoSP (Architecture oriented Software Process) for software processes reuse based on software architectures. The solution is proposed after the study of existing works on software process reusing. AoSP approach deals with the engineering "for" and "by" reusing software processes, it exploits the progress of two research fields that promote reusing in order to improve the software process reusing: domain ontologies and software architectures. AoSP exploits a domain ontology to reuse software process know-how, it allows retrieving, describing and deploring software process architectures. This article details the engineering "for" reusing SPs step of AoSP, it explains how the software process architectures are described and discusses the software process ontology conceptualization and software process knowledge acquisition
