What TriplyDB is

TriplyDB stores, shares, explores, and serves linked data knowledge graphs through APIs. Users can import data from an existing dataset, a public URL, or local files, then explore it with a linked data browser, table, or SPARQL IDE. Supported uploads include RDF, CSV, TSV, XML, JSON, and JSON-LD, along with RDF formats such as Turtle, TriG, N-Quads, N-Triples, and RDF/XML. An upload can contain up to 1,000 separate files; archives may contain any number of files of any size. Data can be exposed through SPARQL 1.1, GraphQL, Elasticsearch, Linked Data Fragments, and REST APIs. Data stories pair explanatory text with query results and can be shared by URL or embedded in a webpage. Datasets, queries, stories, and groups support private, internal, and public access levels. Public data can be queried without authentication, while API writing and access to internal or private data require a token. TriplyDB is free, available on the web and through APIs, and can be self-managed or hosted by Triply.
