In today’s increasingly data-driven world, the ability to connect and manage data efficiently is invaluable to organizations, especially small and medium-sized enterprises (SMEs) that may lack extensive IT infrastructure. Core Building Block Connector, also known as Prometheus-X Data Space Connector (PDC), is designed to address these challenges by enabling seamless data connectivity and boosting data sharing capabilities across multiple domains. This tool not only simplifies data management but also ensures compliance with strict data protection standards such as the GDPR, making it an indispensable tool for any business looking to remain competitive and compliant in the digital age.


Data Accessibility with the Prometheus-X Catalog Service: Since the first quarter of 2023, an innovative initiative is set to transform how organizations access and manage data across the expansive Prometheus-X network. Visions, a key member of Prometheus-X, has led the development of a pioneering catalog service, with the first version that has just launched.


The digital age has changed the way companies manage and share data. Streamlined processes and compliance are more important than ever. In this context, the core Building Block “Contract” service plays an essential role. This tool is part of a comprehensive suite designed to simplify and secure the complexities of data management and sharing, particularly within large data spaces. As organizations become increasingly reliant on big data, the need for efficient and secure data sharing agreements becomes more pressing.


The capacity to manage and share data responsibly is essential for preserving user trust and ensuring compliance with global data protection regulations. Core Building Block Consent serves as a fundamental component in this landscape, offering a robust framework for managing data permissions within the digital space. As part of a larger data exchange ecosystem, this building block is not just a tool, but a foundational element that empowers users and strengthens the integrity of data transactions.

Empowering Data Sovereignty with the Consent/Contracts Negotiating Agent

The Consent/Contracts Negotiating Agent represents a significant advancement in managing the complexity of data consent and contractual agreements within diverse dataspace ecosystems. This innovative technological framework is specifically designed to streamline the setting of consent preferences, automate responses to consent requests, and facilitate the management of contractual agreements between individuals and organizations. With features that are aligned with modern data standards and legal requirements, the tool not only simplifies the management of consent but also ensures personal data is utilized in a manner that respects user preferences and compliance mandates.

Decentralized AI Training: Entering a New Era with Prometheus X

In our digital age, data protection is not just a priority, it is a right. Prometheus X’s decentralized AI training approach redefines AI development by prioritizing confidentiality while democratizing access. This method not only ensures data privacy, but also paves the way for innovation in areas such as healthcare and education. By keeping data at the source, Prometheus X improves model accuracy and diversity, promoting a more equitable technology landscape. Join us as we explore this innovative initiative, where every step forward is a step towards a more inclusive and secure digital future.

Pioneering AI Processing via Edge Computing

Against a backdrop of increasing privacy concerns and the growing need for efficient data management, Prometheus-X is introducing AI processing through edge computing. This groundbreaking initiative places processing power right at the edge of the data, preserving privacy and improving operational efficiency within a distributed infrastructure. By placing processing functions close to the source — using Functions as a Service (FaaS) and Container as a Service (CaaS) — this approach minimizes data transfer, optimizes resource utilization and protects sensitive information. This strategy not only supports data integrity, but also contributes to the different requirements and promotes a scalable and sustainable approach to data processing. Dive into the intricacies of this transformative technology and discover its profound impact on areas such as education, where it enables secure, decentralized learning and the development of skills essential for today’s dynamic job market. Join us on the journey to a smarter and safer digital future.

Trustworthy AI Assessment: Ensuring Transparency and Trust

In the dynamic world of AI, LORIA and AffectLog’s Trustworthy AI Assessment initiative is central to fostering trust and transparency. This program integrates two sophisticated platforms — LORIA’s audit platform for data and algorithms and AffectLog’s risk assessment tools and services. Together, they provide a robust framework for the ethical evaluation and monitoring of AI algorithms.

These platforms improve the transparency, fairness, and safety of AI technologies, which are critical for stakeholders in the education, healthcare and technology sectors.

By providing detailed insights and safety assessments, they set new standards for AI trustworthiness and facilitate ethical AI use. Discover how these platforms and services can change the landscape of AI trustworthiness.

This approach is supplemented by an implementation of automated analysis of software models and AI trustworthiness indicators with respect to the aspects explainability, data security, privacy, and fairness developed by Fraunhofer ISST and University of Koblenz.

Learning Records Converter

Learning Records are available in many formats, either standardized (xAPI, SCORM, IMS Caliper, cmi5) or proprietary (Google Classroom, MS Teams, csv, etc). This wide vairety of format is a barrier to many use cases of learning records as this prevent the easy combination and sharing of learning records datasets from multiple sources or organizations.

The objective of this building block is to specify and develop APIs type “parser” to convert educational traces from one standard to another. Depending on the software and tools used in the field of education and training (LMS, LXP, ENT, etc.) several standards coexist in terms of data model of learning traces: SCORM, xAPI, cmi5, IMS Caliper, etc. This task will allow to combine learning traces data sets expressed in different standards.

Edge Translator: Bridging the Data Divide

Edge Translator revolutionizes the interoperability of data by seamlessly translating different ontologies into a unified format. This technology ensures the alignment of data formats and languages in real time, improving cross-platform data exchange. The flexibility and efficiency of the system, supported by the integration of external services, make it indispensable for ensuring a seamless flow of data. Whether it’s facilitating applications across language barriers or enabling consistent data interaction across different systems, Edge Translator is a dynamic solution to the challenges of global data communication. Discover the potential of Edge Translator in transforming digital interactions.

Refining Personalized Learning Through VR and Learning Analytics: A Vision for Democratized Education

Virtual Reality has a very interesting potential. This is even truer in the context of training, because it enables situations that are difficult to reproduce in the normal way. This enables the learner to work in a safe, low-cost environment. VR also enables the trainer to monitor the learner’s level. Sensors provide precise data that is difficult to measure in a real environment. This data can be fed into an artificial intelligence system, enabling individualized teaching. This makes it easier to make decisions and choose the best course of action for students. The creation of individualized learning paths, adapted to each student, is greatly facilitated by VR.

Data Alignment, Aggregation and Vectorisation (DAAV)

At a time when education and training are rapidly evolving to meet the individual needs of learners, two groundbreaking concepts are leading the way towards a more inclusive and efficient learning landscape: Data Alignment, Aggregation and Vectorization (DAAV) and Distributed Learning Analytics. These initiatives not only promise to transform the way learning data is managed and used, but also aim to democratize personalized learning across Europe.
