Capabilities and features
Public linked-data capabilities are exposed as read-only exploration tools.
Stable dataset and entity URIs
Resolve datasets and RDF resources through stable MatPortal URLs for notebooks, citations, and linked-data reuse.
RDF content negotiation
Serve HTML for people and Turtle, JSON-LD, RDF/XML, or N-Triples for tools from the same resource identifiers.
Catalogue facets
Filter public datasets by project, organization, tag, language, license, format, and related ontology context.
Resource previews and downloads
Show linked files, access URLs, formats, and lightweight previews without exposing unpublished resources.
DCAT JSON-LD catalogue
Publish machine-readable catalogue metadata for harvesters, search portals, and external data platforms.
Schema.org dataset metadata
Expose search-engine-friendly dataset metadata with creators, identifiers, licenses, and distributions.
Public dataset Q&A
Answer plain-language questions from public catalogue metadata with cited dataset evidence when available.
Graph-aware data explorer
Rank datasets using named graphs, RDF entities, resources, and evidence links instead of keyword matches alone.
Query the public data
Public SPARQL execution is temporarily unavailable. Bounded query validation remains available in the workbench.
