Same directive. Different data.
Each institution implements the same standard its own way. Every exchange becomes a new harmonisation project, and cross-border services stay harder than they should be.
For Public Institutions
Public data that speaks one language.
Meaningfy builds semantic interoperability solutions for EU institutions, member states, and public agencies — shared vocabularies, data catalogues, and reference data that keep meaning intact as data moves across systems, institutions, and borders.
The interoperability gap
Every institution speaks its own data language
Public data is abundant. Shared meaning is not — and that is what makes every exchange between institutions slow and expensive.
The data exists. Nobody can reuse it.
Valuable datasets sit in institutional silos — undocumented, unfindable, locked in local formats. Citizens, researchers, and policy makers pay the price.
Every report, rebuilt by hand.
Cross-institutional reporting and EU obligations consume expert time reconciling definitions and code lists instead of producing insight.
Interoperability is not an IT integration problem — it is a meaning problem. Shared semantics, open standards, and governed reference data are how public data becomes exchangeable, reusable, and trustworthy.
What we deliver
Interoperability you can govern
Three building blocks public administrations actually need — built on open standards, delivered as open source wherever possible, with no vendor lock-in.
Semantic data specifications.
Ontologies, application profiles, and mappings aligned with EU standards — so institutions exchange data without losing meaning. We co-authored specifications like the eProcurement Ontology used across EU public procurement.
Findable, documented, reusable data.
DCAT-AP-based data catalogues that make datasets discoverable across institutions and portals — properly described, versioned, and ready for reuse instead of buried in silos.
One source of truth for code lists.
Controlled vocabularies, authority tables, and reference data governance — every system, form, and report uses the same official values, maintained in one place.
Proven in production
Built for and with EU institutions
Not pilots — production systems and specifications in daily use across the European public sector.
One model for EU public procurement
We helped build the ontology that unifies public procurement data across the EU — the shared language behind interoperable procurement systems.
Procurement notices, past to future
Transforming the past, present, and future of EU procurement notices into linked, queryable, standards-based data.
Specifications, maintained at scale
Our open-source toolchain streamlines how semantic data specifications are developed, validated, and maintained over time.
Evidence for policy, from text
Semantic textual analysis of EU and member-state COVID-19 measures — turning legislation into data that supports policymaking and transparency.
Open standards. Open source. No vendor lock-in — the way public infrastructure should be built.
How we work
Start small. Prove value. Then scale.
No big-bang project and no platform to buy. Each phase ends with results you can evaluate before deciding on the next.
The first step is a 1–2 day workshop. That's the whole commitment.
-
01
Discovery workshop
1–2 daysWe map your data landscape with your teams, identify where unclear meaning costs you most, and select the highest-value use case. You leave with a written assessment and a recommended path.
-
02
Semantic strategy
4–6 weeksWe design the foundation: target architecture for your environment, a governance model, and a prioritised roadmap — aligned with EU standards and your procurement realities.
-
03
Proof of Value
6–10 monthsWe build the solution for the selected use case, on your data and your infrastructure, with success criteria agreed up front. Working software, not slides.
-
04
Deploy & scale
ContinuousWe extend across domains and hand over properly — training, documentation, and governance — so your teams own it. No dependency on us, no lock-in.
