ZBW SPARQL Endpoints (beta)

Our previous public SPARQL endpoint used SPARQLite, which is a great tool, especially re. integration of full text (LARQ) indexes. It delivers however only JSON (application/sparql-results+json) results. This causes tools which expect RDF/XML to fail. Additionally, it is not developed actively any more. Therefore we have changed to Joseki.

Additionally, we now offer different datasets. Please use for:

STW Thesarus for Economics: http://zbw.eu/beta/sparql/stw (Form)
STW data created by ZBW - Leibniz Information Centre for Economics, GBI/Genios and ifo Institute
Economists subset of GND: http://zbw.eu/beta/sparql/econ_pers (Form)
Data extracted from GND (created by DNB German National Library and the German scientific libraries)
Economics institutions subset of GND: http://zbw.eu/beta/sparql/econ_corp (Form)
Data extracted from GND (created by DNB German National Library and the German scientific libraries)

Standard Joseki tools and documentation follow:

SPARQL Services

The forms above use the following services, which may be accessed directly using the SPARQL protocol:

sparql : a general purpose SPARQL processor that processes graphs from the web.
books : a SPARQL processor that answers queries on small books database only.

SPARQL is defined by 3 documents:

Complete download from the Joseki download page which includes this set of services.

The Joseki download consists of the following RDF systems:

Joseki : A SPARQL Service Processor
ARQ : A SPARQL query engine for Jena
Jena : An RDF Framework for Java

In addition, the following Jena storage systems work with Joseki:

TDB: a custom storage engine
SDB: a storage engine using relational database technology
