Package com.bigdata.rdf.inf

This package provides an eager closure inference engine for most of the RDF and RDFS entailments and can be used to realize entailments for owl:sameAs, owl:equivilentClass, and owl:equivilentProperty.

Interface Summary
IJustificationIterator Interface for chunked Justification iterators.
 

Class Summary
AbstractSPOBuffer Deprecated. by AbstractArrayBuffer, but this class is more tightly coupled to the AbstractTripleStore.
BackchainOwlSameAsIterator  
BackchainOwlSameAsPropertiesIterator Provides backward chaining for property collection and reverse property collection on owl:sameAs for all access paths.
BackchainOwlSameAsPropertiesPIterator Provides backward chaining for property collection and reverse property collection on owl:sameAs for the ?P? and ??? access paths.
BackchainOwlSameAsPropertiesPOIterator Provides backward chaining for reverse property collection on owl:sameAs for the ?PO and ??O access paths.
BackchainOwlSameAsPropertiesSPIterator Provides backward chaining for property collection on owl:sameAs for the SP? and S?? access paths.
BackchainOwlSameAsPropertiesSPOIterator Provides backward chaining for property collection and reverse property collection on owl:sameAs for the SPO and S?O access paths.
BackchainTypeResourceIterator Provides backward chaining for (x rdf:type rdfs:Resource).
BackchainTypeResourceIterator.PushbackFilter<E> Filterator style construct that allows push back of a single visited element.
BackchainTypeResourceIterator.PushbackIterator<E> Implementation class for BackchainTypeResourceIterator.PushbackFilter.
ClosureStats Statistics collected when performing inference.
FullyBufferedJustificationIterator Fully buffers and then visits all Justifications for a given statement.
Justification A justification for a StatementEnum.Inferred statement.
Justification.VisitedSPOSet A collection of SPO objects (either fully bound or query patterns) that have already been visited.
JustificationIterator Deprecated. replace with appropriate access path reading on the justifications index for SPORelation (or treat as a secondary relation).
OwlSameAsPropertiesExpandingIterator  
RdfTypeRdfsResourceFilter Filter matches (x rdf:type rdfs:Resource).
SPOAssertionBuffer Deprecated. by AbstractElementBuffer.InsertBuffer and AbstractSolutionBuffer.InsertSolutionBuffer and the changes to how truth maintenance is handled (by rule rewrites).
SPORetractionBuffer Deprecated. by AbstractElementBuffer.DeleteBuffer and AbstractSolutionBuffer.DeleteSolutionBuffer and the changes to how truth maintenance is handled (rule rewrites).
TruthMaintenance The TruthMaintenance class facilitates maintaining the RDF(S)+ closure on a database as SPOs are asserted or retracted.
VarOrId A class that models either a constant identifier for an RDF Value or an unbound variable.
 

Package com.bigdata.rdf.inf Description

This package provides an eager closure inference engine for most of the RDF and RDFS entailments and can be used to realize entailments for owl:sameAs, owl:equivilentClass, and owl:equivilentProperty.

The following entailment rules are NOT implemented. In general, these tends to conclude relatively useless information and lead to a large expansion of the KB.
