NGI ONTOCHAIN Funding for Babelfish

Babelfish: Service Integration in Heterogeneous Environments has been selected for funding as one of the brightest projects for building the Next Generation Internet in Europe


OwnYourData and the Kybernos ESG Data Services GmbH are taking part in ONTOCHAIN, to co-develop a new software ecosystem for trusted, traceable & transparent ontological knowledge


ONTOCHAIN is a new software ecosystem for trusted, traceable & transparent ontological knowledge management funded by the European Commission as part of the Next Generation Internet initiative (NGI).

ONTOCHAIN empowers internet innovators to develop Blockchain-based knowledge management solutions that address the challenge of secure and transparent knowledge management, as well as service interoperability on the Internet.

The ONTOCHAIN software ecosystem aims to demonstrate its potential in high impact domains, such as eHealth, eGovernment, eEducation, eCommerce, decentralised infrastructures and similar, in order to achieve trustworthy information exchange and trustworthy and transactional content handling.

Babelfish is taking part in ONTOCHAIN to provide service integration in heterogeneous environments. Our project proposes to describe services on a technical, semantic, and governance layer and will implement a component that uses such descriptions to translate interfaces (APIs), data, and data agreements from a foreign (and maybe proprietary format) to an interoperable format understood by the recipient. A registry maintains a list of all services and thus spans up an interoperable data space.


ONTOCHAIN Open Call 3 was looking for interoperable and sustainable applications that employ Semantic Web and Blockchain concepts, to enhance data quality aspect, as well as the trustworthiness of data communication and handling processes.

Web3 innovators were invited to propose applications covering real needs of end users in vital sectors of the European economy, built on top of the software services of the ONTOCHAIN ecosystem. Applicants could also submit proposals around missing blocks of the ONTOCHAIN infrastructure.

A total of 105 projects applied for the call and the evaluation process resulted in the selection of 14 proposals addressing the following topics:


  • Service Integration (Gateways APIs) for ONTOCHAIN applications
  • Energy-efficient and sustainable hosting infrastructure for the ONTOCHAIN software ecosystem and services


  • Semantic Digital Logbooks for Companies, Buildings, Cars or similar
  • Decentralised Fact Checking and Data Credibility for Social Content
  • Semantic energy data management
  • Automotive, e.g., electric vehicle charging, road side management, car insurance, communication interoperability
  • Distribution Logistics / Supply Chains Using Trustworthy Semantic Data
  • Data/Digital content /Multimedia marketplace, including social media
  • Decentralised Public Services & Common Goods
  • Other applications aligned with ONTOCHAIN objectives

ONTOCHAIN will support Babelfish through a 10-month programme and provide funding support up to 119.500 Euros. As part of the action, experts in diverse fields will also provide technology development guidance, working methodology, as well as access to top infrastructure, coaching, visibility and community building support.

Semantic Overlay Architecture

One of the goals in our current FFG-funded project IDunion was to develop a framework for managing different data models of Covid19 Credentials. In the course of our project we implemented this functionality through the Semantic Overlay Architecture (SOyA 🌱) and this blogposts provides an introduction to this new technology.

IDunion Project Start

There are currently a few initiatives around the world that want to develop digital vaccination records and bring them to market. However, the past has shown that even established solutions such as the international vaccination certificate (“Yellow Card”) cannot be digitized so easily.

Digital Immunization Passport Project Completion

This blog post summarizes the key highlights of the Digital Immunization Passport (DIP) project. We implemented and evaluated an end-to-end workflow for handling immunization information in a human-centric way, and we provided the necessary infrastructure for all participating stakeholders to demonstrated the functionality in real-world use cases: Yellow Fever and Tick-borne encephalitis vaccination. The project […]

DAPSI: DIP Project Funding Extended into Phase 2

OwnYourData & Human Colossus Foundation have been selected for the 2nd phase in the Data Portability & Services Incubator (DAPSI) to continue development of the Digital Immunization Passport  project. From September 2020 to January 2021 we developed the first version of a Digital Immunization Passport for Yellow Fever and demonstrated the feasability of such a […]

Data Vault Deployment

Data Vault Deployment

Docker is required to install and run OwnYourData. The data vault is installed on the commandline and requires the following 5 docker images:

  • Database: postgres:9.6.4
  • Message Broker: rabbitmq:3-management
  • OwnYourData Data Vault: oydeu/oyd-pia2
  • Schedulder: oydeu/srv-scheduler
  • Running periodic tasks: oydeu/srv-worker

A script on Github is available for configuring and starting Docker containers. Run the following command in an empty directory to download and start the script:

bash <(wget -qO-

You have to provide the following four pieces of information:

  • IP address of the computer on which you want to run the data vault
  • Port number under which the data vault is to be reached
    (default value: 3000)
  • Gmail address for sending emails – necessary to create an account in the data vault and to send the weekly data summaries (eg:
  • the associated password to the Gmail address

The data vault is then available under the respective IP address and user accounts can be set up. The following blog posts describe how to use OwnYourData on your own NAS (such as Synology) and on an Asus VivoMini.

Managing Personal Data in Emergency Calls

In the DECTS project – funded by NGI TRUST Grant Agreement No. 825618 – OwnYourData and DEC112 implemented a Proof-of-Concept to demonstrate sharing personal data between an emergency caller and a control room.

Problem Description

The DEC112 App for deaf emergency chats allows users to store personal information (profile data) at the phone to be automatically shared with an operator in a control room when an emergency chat is initiated. But storing this profile data has a few disadvantages like inability to migrate this data when switching phones and also security concerns (anyone gaining access to this phone can read and edit the data). It therefore makes sense to also provide an option to store this emergency information securely in the cloud which in turn generates several challenges:

  • referencing and accessing emergency information in the cloud
  • migrating between cloud storage providers (GDPR Article 20 – Right to Data Portability)
  • guaranteeing secure storage of profile data

This blog posts describes the implementation of managing profile data in a Personal Data Store addressing the above-mentioned challenges.

Self Sovereign Identity

Decentralized Identifiers (DID) provide an elegant and self-determined way of managing access to personal data. Using cryptographic methods and blockchain technology a user can generate a DID (i.e., a unique token) that references a DID Document. In this document a service endpoint can be specified that provides a certain type of service. Since only the user is in possession of the cryptographic key to manage the DID Document it can be edited only by this user.

For the given use case of deaf emergency chats the DEC112 app automatically generates a DID at user registration and to reference an account in the OwnYourData Data Vault (source available here: The user has the option to choose between storing the data on the phone or in a Personal Data Store and when choosing Personal Data Store the respective DID is shown on the Profile page.


Shamir’s Secret Sharing

The OwnYourData Data Vault is a Personal Data Store that recently received the MyData Operator Status and is used as the default cloud storage for personal information associated with an DEC112 user account. Since it stores personal data End-to-End encrypted it was necessary to develop a solution to exchange this encrypted data with a control room. The component that manages data provisioning in case of an emergency chat is called PI2 (Personal Identifiable Information) – source code available here:

Upon creating an account in the OwnYourData Data Vault two key parts a created using the Shamir Secret Sharing scheme. One key part remains in the Data Vault while the other key part is sent to all participating PI2 services located in the respective control rooms. The profile data can only be decrypted when both key parts come together. Additionally, the Personal Data Stores logs any access to the encrypted profile data to guarantee complete documentation.

The data flow for accessing profile data during an emergency chat is displayed in the following sequence diagram.

The basic steps in providing personal information upon initiating an emergency chat include:

  1. The Viewer (client-side application used by the Call Taker) requests from PI2 additional information about the Emergency Call based on the DID delivered along the emergency chat.
  2. PI2 resolves the DID (i.e., retrieves the DID document) and gets the service endpoint of the PDS holding emergency information
  3. PDS sends encrypted emergency information together with one key part for decryption
  4. PI2 combines stored and provided key parts to decrypt emergency information and responds to Call Taker


This blog post described the infrastructure to share data in a secure and self-determined way. Users leverage capabilities of DIDs to manage a trusted service endpoint and use Shamir’s Secret Sharing scheme for a purpose-based data provisioning. A working prototype was implemented for the DEC112 project in Austria.


NGI DAPSI Funding for Digital Immunization Passport

Digital Immunization Passport has been selected as one of the brightest data portability projects in Europe

NGI Innovators

OwnYourData and the Human Colossus Foundation have been selected to take part in the Data Portability & Services Incubator (DAPSI), a 3-year EU funded project that empowers internet innovators to develop new solutions in the data portability field.

What is DAPSI?

The Data Portability and Services Incubator (DAPSI) is a EU funded project, under the European Commission’s Next Generation Internet (NGI) initiative, to empower top internet innovators to develop human-centric solutions, addressing the challenge of personal data portability on the internet, as foreseen under the GDPR and make it significantly easier for citizens to have any data which is stored with one service provider transmitted directly to another provider.

DAPSI will support top-notch projects through a 9-month incubation programme where experts in diverse fields will provide a successful working methodology, access to top infrastructure, training in business and data related topics, coaching, mentoring, and a vibrant ecosystem. On top of that, each DAPSI project can receive up to €150k equity-free funding.

Digital Immunization Passport (DIP) is taking part in DAPSI to create a state-of-the-art digital certificate of vaccination. Currently, vaccination and immunization information are spread over different organizations like labs and hospitals as well as pharmaceutical companies together with government agencies. A patient usually only has a paper certificate that provides vaccination treatments with often difficult to read handwritten additional information. In the proposed solution OwnYourData and Human Colossus Foundation will develop an end-to-end data flow that:

  • connects to various immunization information providers,
  • aggregates, harmonizes, and semantically annotates the data,
  • makes this data-set available in an open format accessible for Personal Data Stores (PDS), compliant to the MyData Operator guidelines,
  • provide a human-centric data management platform for health information,
  • allows to prove immunization status through Verifiable Credentials, and
  • packages selected health data for processing by 3rd parties together with a well-defined usage policy and a provenance trail.

The main focus of this project is on Data Interoperability & Compatibility through establishing interfaces between health industry and individuals as well as pushing forward on standardized interfaces for PDSs. Additionally, we address Data Transparency (Usage Policies and Data Provenance in Semantic Containers) and Security & Privacy (by applying blockchain technology and digital watermarking on data sharing).


How does it work?

In the two-phase supporting programme, the projects will develop advanced solutions in the Data Portability field. From September 2020 to February 2021 (Kick-Start phase) they will develop a solution related to a specific use case. The best projects will progress to the second phase (Booster) where the use cases will be fostered to evolve into solid projects to gain enough traction for deployment and get ready for the market.

OwnYourData is MyData Operator 2020

A bold new initiative to shape the new normal of data has arrived – MyData Operator 2020 status awarded to OwnYourData.

In July 2020, OwnYourData was awarded the inaugural status of MyData Operator 2020. The award was given to 16 world-leading organisations from 12 countries, all working for humans-centric approaches to personal data.

A MyData operator, as described in the white paper Understanding MyData Operators, is a provider of infrastructure for personal data management and a key element in creating sustainable ecosystems for fair and ethical use of personal data.  MyData operators provide interoperability at the technical, informational and governance levels to support the flow of personal data across services. They are examples of a human-centric approach to what the recent EU data strategy calls “novel data intermediaries” and which are set to play a critical role in the provision of the strategy’s vision of data spaces.

Radical collaboration for human-centric data control

The awarded organisations are working together with their competitors on areas of mutual interest to create a successful, interoperable personal data ecosystem. “MyData Global congratulates awardees for their integrity, dedication, and openness in this unprecedented sharing of information that goes far beyond the requirements of any regulation. Ultimately, it is individuals who will benefit from this shared understanding of MyData operators – with increased transparency, better choices, and more innovative, responsible services,” explains Joss Langford, co-lead of the MyData Operators Thematic Group and the lead editor for Understanding MyData Operators white paper.

More information

The organisations awarded the MyData Operator 2020 status are listed here:

The MyData Operator 2020 Award was created by the internationally recognised nonprofit MyData Global. The award acknowledges organisations that place the individual at the centre of personal data about them, provide tools to help them manage personal data, and have the individual as the primary beneficiary of this data.


Certificate of Award

Diabetes Data Processing

In the NGI funded MyPCH project OwnYourData developed several technologies for secure and traceable data exchange of diabetes data: Digital Watermarking, Semantic Annotation, and Data Traceability. In addition, we also participated in a MyData Health initiative to write a feature article for the European Medical Writers Association (EMWA) and we are proud to announce that the article written by 14 individuals from 9 countries around the 6 MyData principles is already published and public available via the EMWA journal website – see section “Data Interoperability” and “Establishing trust between stakeholders for health data use” for example use cases of Semantic Containers.

In this blog post we cover the successful integration of diabetes data into the OwnYourData Data Vault. In this data flow, persons with diabetes (Pwd) can not only transfer their data to a Personal Data Store but also perform SPARQL queries to combine their diabetes data with public information – more information and examples are available here.

A special feature in the OwnYourData Data Vault is the Personal Knowledge Graph shown on the left side of the main screen. It compiles available data from the respective user and presents the information in a clear form. The screenshot below shows information about recent GPS Data, blood sugar levels over the course of a few days, as well as record numbers overall.

Beyond information in the Personal Knowledge Graph plugins allow further data exploration. In the course of the MyPCH project however, we decided to use existing tools like R or Jupyter Notebooks to provide more sophisticated visualization and analysis mechanisms. The R-Notebook available on Github is an example how to retrieve and decrypt information in the Data Vault and compile a report.
