We have a new open source project. The rya-ingest-nifi-processor facilitates ingesting triples into Rya via a NiFi dataflow pipeline. In case you are not familiar, Rya is a project undergoing incubation at the Apache Software Foundation. From the Rya website:
Rya (pronounced “ree-uh” /rēə/) is a cloud-based RDF triple store that supports SPARQL queries. Rya is a scalable RDF data management system built on top of Apache Accumulo®. Rya uses novel storage methods, indexing schemes, and query processing techniques that scale to billions of triples across multiple nodes. Rya provides fast and easy access to the data through SPARQL, a conventional query mechanism for RDF data.
The rya-ingest-nifi-processor is available under the Apache Software License, version 2.0.
