Apache Rya
What Apache Rya is
Apache Rya is a free, open-source triple store for managing RDF data. It provides storage, retrieval, and analysis, and supports SPARQL queries. The project describes its storage, indexing, and query processing as scaling to billions of triples across multiple nodes. Supported RDF formats are RDF/XML, N-Triples, Turtle, N3, TriX, and TriG. Rya is built on Apache Accumulo and also implements a MongoDB backend. It supports reasoning and hybrid deployment options. 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 asks users to verify source distributions with a PGP signature or SHA-512 hash. The project states that Rya is licensed under Apache License, Version 2.0. Release 3.2.11 highlighted Spark, revived Giraph, and GeoWave support, and added Kafka export for the Rya trigger service. That release also added multi-variable GeoSPARQL functions and combined geospatial and temporal indexing for Mongo-backed Rya. For usage questions and help, the community points users to the developer mailing list and invites bug reports, patches, and contributions to code and documentation.
