Querying Drosophila In-Situ Expression Data using SPARQL and D2RQ

Introduction This document describes a SPARQL endpoint for a database containing annotated images of gene expression in fruitfly embryogenesis. The images depict the actual expression of genes at a microscopic level using a technique called insitu hybridisation. The results were recorded in a relational database, and the images were annotated using the fly anatomy ontology. The relational database and experiments are described in [1]. A description of the database and traditional CGI interface can be found here: • http://www.fruitfly.org/cgi-bin/ex/insitu.pl • http://fruitfly.org/ex/Annotation.htm
