LISSU: Continuous Monitoring of SOA Communication with Constraint-Based Validation

Abstract Service-oriented architectures (SOA) are becoming more widespread in the context of Industry 4.0, and their interface descriptions enable modular scalable communication systems. Since syntactic checks such as data types solved nowadays, purpose this work is to add semantic validation based on idea Semantic Web Services. This paper proposes Lightweight Services for Units (LISSU) integrates promising concepts from into SOA. We complement existing with ones (e.g. units), extend one-time initial continuous monitoring, include expressive constrain-based validations. LISSU can be integrated any SOA significantly increases predictability communications. Before components communicate, it semantics via ontology URIs automatically converts units if possible. Continuous monitoring at runtime extracts sent messages guarantees flawless quality constraint-based A real-world demonstrator setup manufacturing domain proves effectiveness practicality. present LISSU, which setups. It enables a wide range validations before during communication, thereby increasing communication.
