LexPons
LexPons develops open standards, methods, and tools for structured, traceable, and reusable legal and regulatory rules.
Mission
Shared open resources for structured legal and regulatory text
LexPons’s mission is to develop and maintain open standards, methods, and tools that make legal and regulatory rules easier to structure, index, interoperate, trace to source, and reuse across documentation, compliance, research, and software systems.
What LexPons Does
Open representations
LexPons develops structured, source-linked representations of legal and regulatory texts that can be reused across documentation and software.
Shared methods and specifications
LexPons publishes methods, schemas, and specifications so implementations can remain reviewable, comparable, and durable.
Interoperability and ecosystem alignment
LexPons contributes to interoperability with adjacent standards and tools, publishing methods and public resources that help structured legal resources move across systems without losing meaning or traceability.
Open resources and tooling
LexPons maintains documentation, datasets, software, and implementation notes that support reuse across projects and organisations.
Current Work
Active projects and ongoing maintenance
Current public workstreams.
Structured regulations
EU AI Act mapping is the leading public workstream, with GDPR and NIS2 progressing as the corpus expands.
Methods and standards
LexPons maintains work around AKN4EU, integrity and traceability rules, and related documentation for structured legal text.
Open documentation and guides
Architecture notes, API references, CLI guides, and self-hosting material remain accessible as supporting public resources.
Experimental implementation surfaces
Transform interfaces, runtimes, and other technical experiments live in the lab and remain available for inspection and testing.
Participation
Come as you are and join an open initiative
LexPons is built by volunteers. This is an open invitation to contribute, not an employment offer. If you care about open knowledge, structured law, or the infrastructure that makes both more accessible and reusable, then there is something here for you.
You might be a developer who wants legal texts to behave like data. A law student curious about what happens when regulation meets computation. A compliance engineer tired of reinventing the same mappings. A researcher who needs structured, traceable sources. A translator. A reviewer. Someone who just wants to read the specs and file a good issue.
All of it matters and moves us forward.
