Global infrastructure speaks open standards.
Legra identifies, describes, queries, governs, and contracts knowledge with W3C and OMG standards. Every claim below carries a precise status.
Standards are connective tissue.
Independently built data, models, policies, and services meet at explicit boundaries. Every participant keeps its own stack.
See standards connect supply and demandEvery standard carries one of four labels.
Standards run inside the operating model.
RDF and Linked Data
IRIs, named graphs, shared vocabularies, and quads form the semantic core.

SPARQL, Cypher, and ISO GQL query and update the same graph.

Inference, rules, and shapes make shared meaning executable.
Explore reasoningPROV-O and graph provenance
Agents, delegation, derivation, tasks, and version history stay queryable as connected provenance.
Inspect the standards fitSupply, demand, and policy each have a standard.
Integrated
DCAT
The W3C catalog vocabulary. Legra publishes governed supply as DCAT and joins federated catalogs.
Emerging standard
DPROD
The Data Product Ontology describes products, ports, dependencies, and lifecycle. Legra adds offers, contracts, delivery, evidence, and settlement around it.
Method lineage
EKG Method
The Use Case Tree Method models demand as outcomes, personas, concepts, and Stories.
Integrated
ODRL
The W3C policy model expresses permissions, duties, and prohibitions inside workspace authority boundaries.
Solid and Linked Web Storage
Legra shares the goal of application-independent data control. It extends the pod idea with versioned graph work, execution, evidence, and economic exchange.
Compare Linked Data and pod serversIPFS-inspired content logistics
Content addressing, encrypted blocks, and peer-to-peer delivery draw on the same ideas. Legra adds workspace authority, graph semantics, and governed change.

Legra grows out of the standards work.
The Enterprise Knowledge Graph community, the DPROD workgroup, and the EKG Method set the direction. Legra turns their vocabularies into running infrastructure.
