Linked data & knowledge graphs
Modelling domains, aligning vocabularies and publishing data as linked, machine-readable knowledge.
Open linked data · Web interoperability · Knowledge valorisation
From scattered data to connected knowledge.
High Latitudes designs and builds data architectures on open web standards, so information can be linked across systems and organisations, reused by people and machines, and turned into lasting value.
Services
What High Latitudes does
From architecture and standards advice to working software in production.
Web interoperability
Standards-based APIs and integrations that let systems and organisations share data without lock-in, including decentralised and confidential data sharing.
Open data & catalogues
Data portals, metadata models, harvesting and quality, so datasets can be found and reused.
Knowledge valorisation & AI
Making knowledge bases useful to people and AI: semantic search, visualisation, and interfaces that LLMs and agents can use.
Featured projects
Projects & experiments
Open source delivered for public open data initiatives, and live demonstrators of data on the web.
ckanext-geoview
Geospatial data previews for CKAN, the leading open data portal platform. Funded by several government open data initiatives, including the Flemish and Brussels regional portals and data.gov.uk, and maintained as part of the CKAN project.
Municipal DB
Data on Belgian municipalities, aggregated from several official sources into one dashboard where citizens can follow their representatives' activity.
RL10
Data journalism: facts gathered from several official sources to trace the history of the teachers' payslip software in the Wallonia-Brussels Federation.
EU Votes
Data mining on European Parliament votes to map the political spectrum and how its members actually vote.
Solidbench
An experimentation platform for Solid-based applications, with retail, music and annotation use cases.
Spatial-CA
A web-based cellular automata engine driven by online geospatial data sources.
Approach
Principles
Open standards first
W3C and OGC specifications over proprietary formats, so data stays usable beyond any single tool or vendor.
Open source by default
Build on and contribute to established open source platforms rather than reinventing them.
Built to last
Simple, documented architectures that teams can maintain and extend for years.
Engagements
Ways to work together
2–4 weeks
Architecture review
An independent assessment of a data platform or tender design, with a written report and a prioritised roadmap.
Project-based
Design & build
Design and implementation of a component: a linked data API, a catalogue harvester, a knowledge graph, a visualisation front-end.
Ongoing
Technical lead on demand
Part-time architecture leadership for a team or consortium, including standards body participation.

Have data to connect?
Describe the project, its data and its goals, and we'll find out together where linked data can add value.
