The SAIL (Storage And Inference Layer) API is a collection of interfaces designed for low-level transactional access to RDF data.
RDF4J supports reading and writing a custom binary RDF serialization format. Its main features are reduced parsing overhead and minimal memory requirements (for handling really long literals, amongst other things).
RDF4J repositories and SAIL configuration can be set up and changed by means of a configuration file in Turtle syntax. Here, we document the way the various components (repositories and SAILs) work together and how a full database configuration can be defined by “stacking” SAILs and wrapping in a Repository implementation.
Eclipse RDF4J is the successor of the OpenRDF Sesame project. The RDF4J framework and tools offer the same functionality, and will continue to be maintained and improved by the same team of developers as Sesame was, under Eclipse stewardship. For any users who wish to migrate their existing projects from Sesame to RDF4J (and we certainly urge you to do so quickly), here’s an overview of what has changed.
Eclipse RDF4J™ is a powerful Java framework for processing and handling RDF data. This includes creating, parsing, scalable storage, reasoning and querying with RDF and Linked Data. It offers an easy-to-use API that can be connected to all leading RDF database solutions. It allows you to connect with SPARQL endpoints and create applications that leverage the power of linked data and Semantic Web.
