Dataset

The IRO Builder has been used to extract data from the ISIS production data store. This includes all investigations where out of the embargo period as of 00:00:00 01/12/13 and all investigations that have a DOI. There are 1440682 triples with 151919 investigations.

The data were written to a ttl file which was then imported into FUSEKI and 4Store.

Platform

Test were carried out on two different triple stores.

FUSEKI http://jena.apache.org/documentation/serving_data/index.html

4Store http://4store.org/

Workflow

The IRO GUI issues seven different SPARQL queries as the user navigates through the pages. Example queries have been extracted so that they can be used in a test program. Each query is run N times against FUSEKI and 4Store triple stores. The test program records the time for the queries and computes the mean values.
