See: Description

Interface Summary

Interface	Description
TripleStore	A storage for triples, supporting named graphs, SPARQL queries, inference and transactions.
TripleTransaction	A triple store transaction.

Class Summary

Class	Description
ForwardingTripleStore	A TripleStore that forwards all its method calls to another TripleStore.
ForwardingTripleTransaction	A TripleTransaction that forwards all its method calls to another TripleTransaction.
LoggingTripleStore	A TripleStore wrapper that log calls to the operations of a wrapped TripleStore and their execution times.
RepositoryTripleStore
RewritingTripleStore	A TripleStore wrapper that rewrites URIs, adapting a prefix used externally in the KS to a prefix used internally to the wrapped triple.
SelectQuery	A SPARQL SELECT query.
SynchronizedTripleStore	A TripleStore wrapper that synchronizes and enforces a proper access to a wrapped TripleStore.

Package eu.fbk.knowledgestore.triplestore Description

TripleStore server-side component API (ks-server).

This package defines the abstract API of the TripleStore internal server-side component, whose task is to support the scalable storage of RDF triples within named graphs (which can be also seen as quadruples), providing reasoning and SPARQL querying facilities on top of it. More in details, the package provides:

• the TripleStore API (TripleStore, TripleTransaction, SelectQuery);
• abstract classes (ForwardingTripleStore and ForwardingTripleTransaction) for implementing the decorator pattern;
• two concrete decorator classes providing, respectively, logging support ( LoggingTripleStore) and synchronization support ( SynchronizedTripleStore).

Note that component API builds on Sesame; however, it does not reuse the Repository or Sail concepts of Sesame, but defines a more lightweight TripleStore interface that allows the implementation of the component on top of a wider range of existing triple store systems. Component implementations for specific triple stores are provided by dedicated modules.
