Corese is a Semantic Web Factory implementing W3C RDF, RDFS, SPARQL 1.1 Query & Update, SPARQL Rules for RDF. It has been redesigned (2011) as a set of libraries and is now based on kgram and on a new graph implementation named kgraph. Corese 3.0 goodies:

Corese API
SPARQL Rules
SPARQL AST

KGRAM stands for Knowledge Graph Abstract Machine. It is a generic SPARQL 1.1 interpreter designed to process labelled graphs including, but not limited to, RDF. The target graph must implement a simple Edge/Node API (Java interface). In order to process SPARQL queries, KGRAM is provided with three brokers:

Producer: enumerates candidate edges from target graph
Matcher: checks that candidates edges match query edges, it may take an ontology into account
Evaluator: evaluates filters given an environment for variable bindings

KGRAM comes with a lightweight implementation of RDF/S using the Edge/Node API and is the core of Corese 3.0, including the following packages:

kgram: SPARQL Abstract Interpreter
sparql: SPARQL Parser, AST, XSD
kgenv: SPARQL Compiler
kgtool: RDF/S Graph, Loader, Printer, kgram brokers
engine: Inference Rule Engine
kgengine: Corese API
kggui: GUI
