“…Due to the recent appearance of the standard, the literature on W3C WoT is still scarce and limited to few applications and supporting tools. The mapping of real-world IoT devices to W3C WTs have been explored in [16], [17], [18] and [19], respectively for the case of mobile phones, automotive industry and wireless sensor networks. Specifically, in the latter, the authors demonstrate how to deploy WoT-based interoperable sensing applications able to manage heterogeneous sensors equipped with three different wireless access technologies (Wi-Fi, BLE and Zigbee).…”

“…The interoperability support is managed at the application level by defining a standard interface for IoT components (physical or virtual), known as the Thing Description (TD) [15], which formally states the Web Things' (WTs) capabilities or affordances. Despite the recent appearance, some interesting applications of the W3C WoT have been proposed so far on different IoT domains [16] [17] [18] [19] [20]. At the same time, the WoT reference implementation [21] does not support mobility of software components among cloud/edge nodes, since the runtime environment of a WT (called Servient in [21]) must be statically deployed on a device.…”

“…However, this promise depends on achieving semantic interoperability across connected devices. The recently proposed W3C WoT Thing Description ontology [33] takes advantage of the standardized Semantic Sensor Network Ontology 6 to provide the first layer of semantics. However, continuous efforts are necessary to align other well-established ontologies with the WoT.…”

Artificial companions and digital assistants have been investigated for several decades, from research in the autonomous agents and social robots areas to the highly popular voice-enabled digital assistants that are already in widespread use (e.g., Siri and Alexa). Although these companions provide valuable information and services to people, they remain reactive entities that operate in isolated environments waiting to be asked for help. The Web is now emerging as a uniform hypermedia fabric that interconnects everything (e.g., devices, physical objects, abstract concepts, digital services), thereby enabling unprecedented levels of automation and comfort in our professional and private lives. However, this also results in increasingly complex environments that are becoming unintelligible to everyday users. To ameliorate this situation, we envision proactive Digital Companions that take advantage of this new generation of pervasive hypermedia environments to provide assistance and protection to people. In addition to Digital Companions perceiving a person's environment through vision and sound, pervasive hypermedia environments provide them with means to further contextualize the situation by exploiting information from available connected devices, and give them access to rich knowledge bases that allow to derive relevant actions and recommendations.

“…For some services, linked data service descriptions will be made available by the service provider. This might be the case for a physical asset, where a Web of Things 'Thing Description' document could be provided on the asset itself or via a proxy to give a JSON-LD Linked Data description of the device's affordances, or its capabilities and how it is to be used, "in order to increase interoperability between connected devices and develop arbitrarily complex mashups" [21]. Similarly, a dataset might be accompanied by a Linked Data description.…”

Fifth generation (5G) mobile networks will revolutionize edge-based computing by providing fast and reliable network capabilities to remote sensors, devices and microservices. This heralds new opportunities for researchers, allowing remote instrumentation and analytic capabilities to be as accessible as local resources. The increased availability of remote data and services presents new opportunities for collaboration, yet introduces challenges for workflow orchestration, which will need to adapt to consider an increased choice of available services, including those from trusted partners and the wider community. In this paper we outline a workflow approach that provides decentralized discovery and orchestration of verifiably trustable services in support of multi-party operations. We base this work on the adoption of standardised data models and protocols emerging from hypermedia research, which has demonstrated success in using combinations of Linked Data, Web of Things (WoT) and semantic technologies to provide mechanisms for autonomous goal-directed agents to discover, execute and reuse new heterogeneous resources and behaviours in large-scale, dynamic environments. We adopt Verifiable Credentials (VCs) to securely share information amongst peers based on prior service usage in a cryptographically secure and tamperproof way, providing a trust-based framework for ratifying service qualities. Collating these new service description channels and integrating with existing decentralized workflow research based on vector symbolic architecture (VSA) provides an enhanced semantic search space for efficient and trusted service discovery that will be necessary for 5G edge-computing environments.

On Modeling the Physical World as a Collection of Things: The W3C Thing Description Ontology

Abstract: This document presents the Thing Description ontology, an axiomatization of the W3C Thing Description model. It also introduces an alignment with the Semantic Sensor Network ontology and evaluates how this alignment contributes to semantic interoperability in the Web of Things.
