(Getting started with snb,
DATAGEN: data generation for the Social Network Benchmark), Arnau Prat discussed
the main features and characteristics of DATAGEN: realism,
scalability, determinism, usability. DATAGEN is the social network
data generator used by the three LDBC-SNB workloads, which produces data
simulating the activity in a social network site during a period of
time. In this post, we conduct a series of experiments …

In this multi-part blog we consider the challenge of running the LDBC
Social Network Interactive Benchmark (LDBC SNB) workload in
parallel, i.e. the design of the workload driver that will issue the
queries against the System Under Test (SUT). We go through design
principles that were implemented for the LDBC SNB workload
generator/load tester (simply referred to as driver). Software and
documentation for this driver is available here: …

LDBC SPB (Semantic Publishing Benchmark) is based on the BBC linked data
platform use case. Thus the data modelling and transaction mix reflects
the BBC’s actual utilization of RDF. But a benchmark is not only a
condensation of current best practices. The BBC linked data platform is
an Ontotext Graph DB deployment. Graph DB was formerly known as Owlim.

So, in SPB we wanted to address substantially more complex queries than
the lookups that …

The Semantic Publishing Benchmark (SPB), developed in the context of
LDBC, aims at measuring the read and write operations that can be
performed in the context of a media organisation. It simulates the
management and consumption of RDF metadata describing media assets and
creative works. The scenario is based around a media organisation that
maintains RDF descriptions of its catalogue of creative works. These
descriptions use a set of ontologies …

The Linked Data Benchmark Council (LDBC) mission is to design and
maintain benchmarks for graph data management systems, and establish and
enforce standards in running these benchmarks, and publish and arbitrate
around the official benchmark results. The council and its
https://ldbcouncil.org website just launched, and in its
first 1.5 year of existence, most effort at LDBC has gone into
investigating the needs of the field through interaction …

The Linked Data Benchmark Council (LDBC) is reaching a milestone today, June 23 2014, in announcing that two of the benchmarks that it has been developing since 1.5 years have now reached the status of Public Draft. This concerns the Semantic Publishing Benchmark (SPB) and the interactive workload of the Social Network Benchmark (SNB). In case of LDBC, the release is staged: now the benchmark software just runs read-only queries. This will be …
