I'm happy to announce the first release of RDFFilter 1.0alpha, a Java- and SAX2(beta)-based package for processing RDF documents, together with a small bundled RDF test suite. Download information is available at http://www.megginson.com/Software/ RDFFilter uses a relatively simple callback-based interface, and unlike DATAX, it doesn't build any in-memory trees, so it's suitable for use with very large documents. The callback interface looks like this: ====================8<====================8<==================== public interface RDFHandler { public static final String featureName = "http://megginson.com/sax/features/rdf"; public static final String propertyName = "http://megginson.com/sax/properties/rdf-handler"; public final static int SUBJECT_URI = 1; public final static int SUBJECT_URI_PATTERN = 2; public final static int SUBJECT_DISTRIBUTED = 3; public final static int SUBJECT_GENERATED = 4; public abstract void literalStatement (int subjectType, String subject, String predicate, String object, String language) throws SAXException; public abstract void resourceStatement (int subjectType, String subject, String predicate, String object) throws SAXException; public abstract void startXMLStatement (int subjectType, String subject, String predicate, String language) throws SAXException; public abstract void endXMLStatement () throws SAXException; } ====================8<====================8<==================== For literal XML content (parseType="Literal"), and non-RDF XML content outside of rdf:RDF, the filter uses regular SAX2 ContentHandler callbacks. There is a simple front-end for people who don't want to have to learn how to set up all the SAX2 stuff.
