Workflow automation is taking over software development systems, helping businesses increase efficiency, accelerate production, and adapt quickly to market changes. Combined with agile principles, it has given birth to the DevOps paradigm. However, practitioners often face an important issue known as vendor lock-in caused by the cost of tool replacement or migration to different platforms. This issue could be addressed by standardising service interfaces to facilitate their integration. Linked Data is an attractive choice for implementing such a standard without sacrificing versatility. Following this approach, the Open Services for Lifecycle Collaboration (OSLC) proposal aims to build an environment where services can interoperate using standard models. Therefore, this article proposes an extension of the existing OSLC specification, based on the Event-Condition-Action (ECA) model, for event-based interoperable automation. This extension enables a new path in the field of semantic automation for OSLC services, which allows the self-interaction of services among them and with human users. The article presents the key concepts of the proposed model and exemplifies its application in an automation scenario with two real-life services. The validation of the proposal has been carried out using established ontology evaluation methods, such as coverage and similarity metrics and competency questions. Full article

Product lifecycle management (PLM) as a holistic process encompasses the idea generation for a product, its conception, and its production, as well as its operating phase. Numerous tools and data models are used throughout this process. In recent years, industry and academia have developed integration concepts to realize efficient PLM across all domains and phases. However, the solutions available in practice need specific interfaces and tend to be vendor dependent. The Asset Administration Shell (AAS) aims to be a standardized digital representation of an asset (e.g., a product). In accordance with its objective, it has the potential to integrate all data generated during the PLM process into one data model and to provide a universally valid interface for all PLM phases. However, to date, there is no holistic concept that demonstrates this potential. The goal of this research work is to develop and validate such an AAS-based concept. This article demonstrates the application of the AAS in an order-controlled production process, including the semi-automatic generation of PLM-related AAS data. Furthermore, it discusses the potential of the AAS as a standard interface providing a smooth data integration throughout the PLM process. Full article

In the field of model-based design of Cyber–Physical Systems (CPS), seamless traceability of the process, from requirements to models to simulation results, is becoming increasingly important. It can be used to support several activities such as variant handling, impact analysis, component reuse, software maintenance and evolution, verification, and validation. Despite the fact that the relevance of traceability in the model-based design of CPSs is well known, current tools that support traceability management are inadequate in practice. The lack of comprehensive whole-lifecycle systems engineering support in a single tool is one of the main causes of such ineffective traceability management, where traceability relationships between artifacts are still manually generated and maintained. This paper aims at presenting an approach and a prototype for automatically generating and maintaining the appropriate traceability links between heterogeneous artifacts ranging from requirement models, through design models, down to simulation and verification results throughout the product life cycle in model-based design of CPSs. A use case study is presented to validate and illustrate the proposed method and prototype. Full article
