Integrating ecological data using linked data principles

Abstract

This paper presents a framework to manage, treat and integrate ecological data in the context of the PELD project, currently in development in Brazil. These data, which are produced and collected from different resources, are stored in distinct relational databases and transformed later into RDF triples, using a traditional relational-RDF mapping. Taxonomical, spatial and trophic relations are explored by means of ontological properties, which make it possible to discover interesting information about existing marine species of different bays in the country, illustrated by SPARQL queries. Additionally, the endpoint thus generated allows data to be accessed on the Web of data, as linked data.
