Context
=========
In recent years, the combination of Internet of Things (IoT), Semantics and Web of Things (SWoT) has been more and more popular to collect sensing data according to the semantic web stack and build smart services and applications. One momentum is the release of a W3C recommendation for WoT architecture along with a formal specification of Thing Descriptions. The Web of Things (WoT) allows to describe device semantics, bridging the gap between the different domain and service descriptions. Developers can use WoT standards and tools to collect sensing data and control devices for the applications in agriculture, energy, enterprise, finance, healthcare, industry, etc.
At the same time, decentralized infrastructures able to capture and transform data at the edge have gained attraction over centralized ones, due to both the constant attempts to reduce industrial costs and the real necessity to reduce the global carbon emission. Decentralized infrastructures hence represent a step towards the so-called Green Web, especially as they are usually built on small and low-energy consuming devices. However, fulfilling the SWoT promises using such infrastructures poses new challenges as these small devices are constrained in terms of computing capabilities and memory. Moreover for autonomous devices, wireless network communications are also energy-consuming and can hinder their battery life. Deploying SWoT standards on such devices require to control and monitor the consumption of these resources, whereas semantic technologies are known to be verbose and computation intensive.

This first international workshop aims at bridging together research and industry communities working on the different aspects of embedding data semantics and standards-based solutions into edge and/or constrained Internet and Web of Things setups, as well as reducing the carbon footprint of semantic technologies.
The workshop will include a keynote presentation, different types of submission (research, in-use, experience, position, tools and demos), and break-out discussions.

Workshop Objectives
====================
The purpose of the workshop is to provide a venue for scientific presentations, systematic analysis and rigorous evaluation of semantic WoT architectures, ontologies and tools, as well as practical and applied experiences and lessons-learned applied to constrained devices both from academia and industry. The workshop can lead to a contribution to the W3C community group on WoT.

Topics of interest include, but not limited to:
================================================
- Ontologies and models adjustments for solving data and service heterogeneity in constrained networks
- Ontology / vocabulary efficient integration and communication among embedded systems
- Extensions of current State-of-the Art ontologies (M2M, SSN/SOSA, SAREF, etc) for sensing, converting raw data for embedded systems
- Knowledge Graph applications, and use cases
- Libraries for creating knowledge graphs at the edge
- Distributed querying and reasoning in edge computing
- Smart brokers to exchange messages between edge and gateways
- Binary RDF formats to efficiently exchange datasets among smart devices
- Low coding approaches applied to constrained devices
- Architectural considerations for constrained devices
- Experimentations / Efficient evaluation of using semantic technologies in constrained devices (memory storage, processing, carbon footprint, network, etc)
- Automatization of knowledge graph construction methods for embedded systems
- Lessons learned/ Best practices for implementing SWoT applications for embedded systems
- IoT application use cases in various domains: healthcare, smart agriculture, smart, transportation, robotics, industry 4.0, etc.
