What TriplyDB is
TriplyDB is a free platform for storing, sharing, exploring, and serving linked-data knowledge graphs. Users can import data from another TriplyDB dataset, a public URL, or local files, including RDF, CSV, TSV, XML, JSON, and JSON-LD. RDF options include N-Quads, N-Triples, RDF/XML, TriG, and Turtle. Uploads support up to 1,000 separate files, while archives can contain any number of files of any size. Data can be explored in a linked-data browser, table, or SPARQL IDE, with SPARQL 1.1 and reasoning support. APIs include SPARQL, GraphQL, Elasticsearch, Linked Data Fragments, and REST. Data stories combine explanatory text with query results for sharing or embedding. Access levels are private, internal, or public. TriplyDB supports web, API, and self-managed deployment, with optional hosting. Triply provides JavaScript, TypeScript, and command-line tools.
