VOStack open-source Software Stack for the virtualization of IoT devices
A Virtual Object (VO) is considered as a virtual counterpart of an IoT device. It provides abstractions for managing any type of IoT device while augmenting the supported functionalities through a multi-layer software stack, called as VOStack. The VOStack is an open-source software stack that supports interaction with both physical IoT devices and edge/cloud computing orchestration platforms. It has three main architectural layers namely: the Physical Convergence Layer, the Edge/Cloud Convergence Layer, and the Backend Logic Layer. The Physical Convergence Layer is responsible to tackle the major challenges of connecting the IoT devices with the computing continuum infrastructure. The Backend Logic Layer is responsible for augmenting the functionalities and capabilities of IoT devices. The Edge/Cloud Convergence Layer is responsible for bringing the VO closer to the application and orchestration layer. The implementation of VOStack is aligned with the specifications provided by the W3C Web of Things (WoT) Working Group. The VOStack is implemented in the framework of the NEPHELE Horizon Europe project.

Synergetic Meta-Orchestrator for Distributed Applications
The Synergetic Meta-Orchestrator (SMO) supports the efficient deployment and orchestration of distributed application graphs over computing and network resources in the computing continuum. It takes deployment requests via the dashboard, formulates deployment plans based on infrastructure status and user-defined requirements, and continuously monitors the system to trigger optimizations when necessary. The SMO interacts with the multi-cluster resource manager and the network resource manager to ensure efficient resource utilization. The SMO is implemented in the framework of the NEPHELE Horizon Europe project.GitLab repository: https://gitlab.eclipse.org/eclipse-research-labs/nephele-project/smo
Fusion
FUSION aims to design and implement an open-source observability and analytics framework that integrates diverse signals (i.e., metrics, traces, and logs). The framework supports efficient collection and analysis of heterogeneous data and exposes the results through open Application Programming Interfaces (APIs). By applying various analysis pipelines to the fused data, FUSION delivers advanced analytics, supports mitigation strategies, and enhances orchestration mechanisms. The developed framework leverages open-source tools (e.g., OpenTelemetry, Prometheus, Grafana, Elasticsearch) and is published under a permissive free software licence. It incorporates the foundational tasks of setting up data collection mechanisms to handle heterogeneous data from diverse sources in accordance with the OpenTelemetry standard, aggregating this data into a unified schema, and implementing APIs to facilitate seamless data integration. It includes prototype AI-based analytics functions and components such as anomaly detection, and root cause analysis. Future development will focus on building advanced reporting/visualization tools.Licence: Creative Commons Attribution Share Alike 4.0 International GitLab repository: https://gitlab.com/netmode/fusion
SustainGraph
SustainGraph is a open-source Knowledge Graph (KG) that considers in a holistic way the tracking of the progress towards the Sustainable Development Goals (SDG). It monitors SDG targets and the evolution of indicators at national and regional levels, along with their relationship with specified policies and the implementation of case studies across Europe. SustainGraph is considered as the basis for the systemic representation of knowledge related to the SDGs, enabling the collection and homogeneous representation of data along with their semantics and overcoming data management barriers (e.g., existence of multiple data silos, absence of semantic alignment of data coming from different disciplines). In addition to tracking the evolution towards the achievement of the targets posed in the SDGs, one of the main objectives of SustainGraph is to enable the development of participatory modeling and analysis processes (e.g., socio-environmental models), taking advantage of the semantic alignment of the represented terms and the knowledge produced through the analysis of the information that is made available. SustainGraph is developed within the framework of the ARSINOE H2020 project.

SDGDetector
SDGDetector is an open-source Python library designed to classify and analyze text data in alignment with the United Nations Sustainable Development Goals (SDGs). It provides a flexible and efficient framework for associating textual content—such as reports, national strategies, or policy documents—with one or more of the 17 SDGs, helping researchers, policymakers, and developers better understand how language reflects global development priorities. At its core, SDGDetector offers two powerful approaches for SDG classification. It supports both a pretrained fine-tuned model for accurate, context-aware SDG classification, and a keyword-based method that uses curated term lists to associate text with relevant SDGs. These approaches can be used independently or combined for more robust and interpretable results. SDGDetector is developed within the framework of the ARSINOE H2020 project. This library is available on PyPI.License: CC BY-NC 4.0 GitLab repository: https://gitlab.com/netmode/sdg-detector
CyVer
CyVer is a open-source Python library designed to validate Cypher queries against a given Knowledge Graph schema in Neo4j. It ensures that queries are not only syntactically correct but also semantically valid with respect to the underlying graph structure, including labels, relationships, and property access. This is particularly essential when Cypher queries are generated by LLMs, where hallucinations or schema mismatches are common. CyVer helps catch and correct such issues early, making it a critical component in systems that rely on AI-generated queries. Whether you’re building intelligent graph interfaces or deploying LLM-driven data access tools, CyVer adds a vital layer of reliability and safety. Cyver is developed within the framework of the ARSINOE H2020 project. This library is available on PyPI. License: CC BY-NC 4.0 GitLab repository: https://gitlab.com/netmode/CyVer
k8s-RL-autoscaler
k8s RL autoscaler is an open-source software project that offers autoscaling mechanisms for serverless applications that are powered by Reinforcement Learning (RL) techniques. A set of RL environments and agents have been implemented (based on Q-learning, DynaQ+ and Deep Q-learning algorithms) for driving autoscaling mechanisms, able to autonomously manage dynamic workloads with Quality of Service (QoS) guarantees, while opting for efficient usage of resources. The produced environments and agents are evaluated in real and simulated environments, taking advantage of the Kubeless open-source serverless platform. A simulation environment has been also developed to support extensive training of RL agents to overcome time-related limitations of real environments. The k8s-RL-autoscaler has been extended towards a multi-agent setting for managing autoscaling mechanisms within an application graph, based on the application of Multi-agent Reinforcement Learning (MARL) techniques. The extended version is called as k8s-marl-autoscaler.

Intent Lifecycle Management Simulation Kit
The Intent Lifecycle Management Simulation Kit manages the intent lifecycle during the deployment of distributed application graphs over multi-cluster/multi-provider infrastructure. Three control loops are defined supporting actions from the intent translation and validation to the intent provision and management across distributed resources, and the intent assessment, reporting, and feedback. The first control loop supports semantic and syntactic validation of the intent description of an application graph. The second control loop manages the intent during application provision, leading to proactive and reactive reconfigurations. The third control loop manages reporting information and provides recommendations for intent refinement. The Intent Lifecycle Management Simulation Kitis implemented in the framework of the 6GREEN Horizon Europe project.GitLab repository: https://gitlab.com/netmode/intent-lifecycle-management
