Apache Rya
What it is
Apache Rya is a triple store for storing, retrieving, and analyzing RDF data at scale. It supports SPARQL queries and the RDF/XML, N-Triples, Turtle, N3, TriX, and TriG formats. The project describes its storage, indexing, and query processing as scaling to billions of triples across multiple nodes. Rya is built on Apache Accumulo and also implements a MongoDB backend; hybrid deployment options and reasoning support are listed. Release 3.2.11 highlighted Spark, revived Giraph, and GeoWave support, added Kafka export for the Rya trigger service, and introduced multi-variable GeoSPARQL functions and combined geospatial and temporal indexing for Mongo-backed Rya. The project distributes Rya as source and through Maven. Its downloads page lists version 4.0.1, dated 22 December 2020, as the newest source release and advises verifying source distributions with a PGP signature or SHA-512 hash. Rya is open source under Apache License, Version 2.0, and is listed as free with no free trial. The community directs usage questions to its developer mailing list and welcomes bug reports, patches, code, Javadocs, and documentation contributions.
