We are happy to announce the availability of the new version of Stardog Sandbox: a free, hosted environment that comes with curated datasets ready to be explored with Stardog Studio in your browser without installing any software.
Stardog Sandbox provides a perfect opportunity for beginners to explore the capabilities of the Stardog Knowledge Graph platform with simple, curated RDF datasets we have put together. Sandbox comes with examples of not only basic graph queries but also features like inferencing, geospatial queries, shortest-path queries, and federation. Interactive Stardog tutorials are included in the Stardog Sandbox to help you learn the basics.
The new version of the Stardog Sandbox is backed by a continously running Stardog High Availability cluster so you can connect to it immediately and start exploring. No registration is required to use the Stardog Sandbox and anyone can connect to it anonymously.
Stardog Sandbox comes with the following datasets:
- Covid-19 US: This dataset is based on the open-source New York Times data that shows county-level Covid-19 cases across the United States. This database is updated daily to load the latest reports.
- Finance: Explore the Financial Industry Business Ontology (FIBO) to see how financial instruments, business entities, and financial processes work across the global financial industry. The dataset uses a small subset of the FIBO ontology for a simpler introduction.
- Movies: Explore movie releases, movie stars, ratings, filming locations and more. This dataset uses the schema.org vocabulary for describing these entities.
- Music: Explore popular musicians, albums and songs as part of interactive tutorials.
