NGI0 Commons Fund Supports 32 Projects Building the Public Internet

In the April round of the NGI Zero Commons Fund, 32 projects have been selected to receive funding for research and development. The programme offers financial and practical support to free and open source projects that reclaim the public nature of the internet.

NGI Zero funding is open to all and in this round we are welcoming projects from at least 14 countries involving people and organisations of various types: associations, small and medium enterprises, foundations, public institutions, universities, and informal collectives. The new projects are all across the different layers of the NGI technology stack: from trustworthy open hardware to services & applications which provide autonomy for end-users. In this particular call we note a particularly strong cluster of project on open data and AI, including the immersive views project Panoramax that augments OpenStreetMap data with street level imagery. iTowns allows to put data on globes and maps, and DatamiPods in addition allows to visualise linkedData (including geospatial data) into charts and graphs — at the nexus of ActivityPub and Solid. EveryDoor helps to keep map data accurate and quickly create new maps for instance in case of humanitarian response and economic development. Applications will have an easier job consuming vector tiles due to VersaTiles. One such prominent application is uMap which lets you quickly build custom maps with OpenStreetMap’s background layers and integrate them on your own website. CityBikes provides a unified API for bike-sharing around the world.

Beyond geospatial data, Open Food Facts and Open Everything Facts contribute to the world's largest open dataset on food and other products.Ontogen/Mud provides tooling for semantic data management, and Smart Semantic Data Lookup experiments with making semantic data easier to use by means of standard SQL databases and modern lightweight data formats. Re-Isearch works on vector datatypes for embeddings and applications like retrieval augmented generation. Federated Code Next aggregates, enriches and federates open data concerning software with vulnerabilities to make it easier to track dangerous software. And Massive FOSS scan will do what it says on the tin: run a massive license scan on the whole Software Heritage archive of over 20 billion unique source code files from more than 300 million projects, contributing to a global database with accurate license information, and a massive collection of fingerprints to enable approximate code matching at scale.

Of course there are also end user applications, such as the communication suite Mustang, exciting new features for LibreOffice/Collabora Online (infinite canvas and follow-me slideshow). More creativity comes from EPE ("Ecran-Papier-Editer"), a new set of innovative, open and alternative, reasoned and sustainable editorial software tools. For makers, there is the free and open source electronics design automation (EDA) software suite LibrePCB. Sniffnet allows to help users keep an eye on their Internet traffic happening in the background, while the intrusion detection system Slips not only monitors local networks but even actively protects users through innovative blocking techniques. F3D lets users visualize and render their 3D models efficiently. Mautic is a privacy preserving online marketing automation platform, that keeps consumer data safe within organisations — and similarly the Analytics Microservice project avoids having to use external trackers in order to understand website visitor behavriour. Land will be building a customisable open-source code editor. The community tool OpenKi allows to discover what you can learn from the people around you, and Decidim provides tooling for community management and participatory democracy. There is also some hardcore tech stuff, for instance performing test Procedures for MOSFET Open Source SPICE model validation as well as a Verilog A-distiller. Bubble-up enables seamless schema migrations for SQLite databases. And Hop3 Nixified offers an open-source orchestration platform for deploying and managing self-hosted applications.

LibrePCB 2.0 — New UI & powerful features for a future-proof LibrePCB

LibrePCB is a free and open source electronics design automation (EDA) software suite to develop printed circuit boards (PCBs). It runs on all major platforms and aims to be easy to use, while still beeing able to create professional schematics and PCBs. While it is already used productively by people all around the world, the development of new features became to stuck because of limitations of the current UI concept. To pave the way for new features, a completely new UI will be developed with the goal of having a unified, tabbed window as known and proven by many other applications. In addition, a first attempt of moving from C++ to the safer language Rust will help us to benefit from modern technologies. Together with more import/export capabilities, performance improvements and other frequently requested features the outcome will be released to users by a new major version LibrePCB 2.0.

Test Procedures for MOSFET Open Source SPICE Model Validation — Test Procedures for MOSFET SPICE Model Validation

The emergence of open PDK initiatives reduce barriers to entry for integrated circuit (IC) design and manufacturing, serves thelong term goal of promoting academic/industrial collaboration, and stimulate innovation in the field of semiconductor IC design. Open PDKs have the potential to "standardize" PDKs (process design kit), and move away from proprietary/licensed EDA vendor formats. This is needed to democratize open source IC design flow and manufacturing. Open PDKs provide open access to IC design resources.

The compact/SPICE models of semiconductor devices are the core of open PDK efforts. SPICE executes implemented Verilog-A compact models. A model of a semiconductor device (passive elements and active, eg: diodes, mosfets, bjts) is primarily a "compact device model". Validation benchmarks are not yet available in the public domain. This project represents the very first attempt to implement these tests for the compact model available in open PDKs. It aims to establish such tests for the compact models in open PDKs, which are intended to be generic enough for model quality assurance testing with FOSS circuit simulators such as GnuCAP, ngspice, xyce, Qucs, among others.

Verilog-A distiller — Automated porting of models from C to Verilog-A

Analog circuit simulators require compact device models in order to be able to simulate circuits. The de-facto standard language for compact device model dissemination is Verilog-A. Many legacy models exist that are coded for the SPICE3 circuit simulator in the C programming language. Manual conversion from C to Verilog-A is resource-intensive, time-consuming, and error-prone. This reduces the accessibility of legacy models and limits innovation. The Verilog-A Distiller project aims to automate conversion of SPICE3 device models from C to Verilog-A. By automating this conversion, we aim to streamline model implementation, reduce development time, and enhance compatibility across different simulators. Verilog-A Distiller is a converter written in Python that utilizes the pycparser library for reading the C code of SPICE3 models. The parsed models are pruned of unnecessary SPICE3-specific parts, upon which Verilog-A code is emitted. Projects like Ngspice put a lot of effort into cleaning up and improving legacy SPICE3 models. Verilog-A Distiller makes these models available across a wide range of simulators that support Verilog-A.

Bubble-up — Declaritive schema migrations for sqlite databases

SQLite is widely regarded as the most-used database engine, with sqlite.org even suggesting that it surpasses all other engines combined. One of its main advantages is its simplicity—operating on a single file. However, while getting started with SQLite is straightforward, modifying the database schema can be more complex due to its limited support for ALTER commands compared to other databases.

Bubble-up is a command-line tool designed to ease this challenge. It enables seamless schema migrations for SQLite databases by comparing your desired schema (written in a simple SQL file with standard DDL statements) to the current database structure, and performing the necessary changes.

FederatedCode Next — UI and curation queue for VulnerableCode data enrichment

VulnerableCode is an open-source database that aggregates and enriches data concerning CVE with metadata to make it easier to track CVEs across packages and dependencies. VulnerableCode was designed from its inception to correlate and aggregate multiple data sources and not have a single point of failure. The FederatedCode Next project aims to create a UI and curation queue for VulnerableCode in order to take the next step towards an open, peer-to-peer federated database of code vulnerabilities.

This allows to to ensure cybersecurity professionals have the essential information they need to do their work when new vulnerabilities are unveiled - such as PURL and VERS version ranges for impacted and fixed package versions, Common Weakness Enumeration details to qualify the weakness exposed by a CVE, severity scoring, mitigation possibilities beside updating and patching, the actual commits/patches that introduce/fix a vulnerability for reachability analysis, related PoC for exploits, etcetera.

Measurement, monitoring, analysis and abuse handling

Analytics Caddy Microservice — Privacy-friendly analytics microservice using server logs

For small organisations and individuals who wish to respect their visitors' privacy while needing to obtain analytics, there are limited options. The most elegant option (and the most privacy-respecting one) is to provide real-time analytics by ingesting the web server logs. This doesn't involve/require doing anything client-side (no scripting, no invisible pixels, etc): all the information needed can be derived from these log files without resorting to tricks. The form factor of a drop-in microservice allows for easy integration into other tools (which offers a significant improvement in terms of usability), and makes it portable. The end result will provide a neat solution for small actors to make self-hosting of their website 'batteries included'.

Open Everything Facts — Powering consumer choice on anything with a bar code

When we started Open Food Facts, it already seemed like a bold endeavour to compile comprehensive food product data into a single database, with far-reaching positive impacts, and the rest is history. Why not extend this concept further? Why should consumers not have the same level of informed decision-making power for products beyond food, like their shampoo, bicycles, refrigerators, or ventilation systems? Our ambition is to integrate our existing product databases — Open Food Facts, Open Product Facts, Open Beauty Facts, and Open Pet Food Facts — into one unified, easy-to-navigate mobile application. This will include a universal scan, a new unified versatile and simplified product page, simplified personal and private preferences, as well as the matching contribution experience. Ultimately, this project is a stride towards a world where transparency and informed choices are the norms, not the exception, in every aspect of consumer goods.

Re-isearch Schmate — Extending re-Isearch with a flat vector datatype for embeddings

Schmate is the development name for the evolving next iteration of re-Isearch adding vector datatypes for embeddings and applications like retrieval augmented generation (RAG). Schmate (pronounced "SHMAH-teh") is Yiddish for rag (שמאטע).

In contrast to typical vector stores the proposed re-Isearch+ shall offer a full passage information retrieval system (index and retrieval) using a combination of dense and sparse vectors as well as structure. It is dense passage retrieval (DPR) and a whole lot more. It addresses the stumbling blocks of chunking, has a tight integration of ingest, tokenisation, a number of alternative vector stores and similarity algorithms and, above all, uses a novel combination of understanding document structure (implicit and explicit) to provide a better contextual passage retrieval to solve the problem of misaligned context. This builds on the observation that meaning is also communicated through structure so needs to be viewed in the context of structure. Since structure like the words are meant by the sender (writer) to be received and understood (reader) our approach is to exploit the original author's organization of content to determine appropriate passages rather than relying solely on the chunks.

Smart lookup & inference for Semantic Data — Knowledge mapping within a postgresql database

Semantic knowledge representations have not evolved since the Semantic Web was proposed during the 1990s. Modern graph databases offer new possibilities for knowledge representation, but the methods are poorly developed and require the use of specialized query languages and clumsy outdated formats. This project aims to make semantic maps easy for general use, using standard SQL databases and modern lightweight data formats. A user workflow starts from a simple note-taking language, then ingesting into a database using a graph model based on the causal semantic spacetime model, to the use of a simple web application for supporting graph searches and data presentation. The aim is to make a generally useful library for incorporating into other applications, or running as a standalone notebook service.
