Sparqling is an RDF store in your browser.
This is a work in progress. It would be better if we contributed better SPARQL 1.1 compatibility (concretely, support for SPARQL 1.1 Federated Queries and SPARQL 1.1 Query Results JSON), and an IndexedDB backend to Antonio Garrote's fantastic rdfstore-js.
Sparqling can import small data sets directly from your hard drive. The most common RDF serialization formats are supported: N-Triples, Turtle, RDF/XML (thanks to @jmandel), and N3.
rdfstore-js
currently relies on localStorage
to persist data in the browser. The maximum amount of data that Chrome allows you to store is 5 MB. There is some overhead for indexing data, so please do not try to import files larger than 2.5 MB.
