Django-Rdflib and PostgreSQL - the best of both worlds

Django-Rdflib is a python library implementing a database with various triples back-end, parser, data serializers, SPARQL is a Python interface to extract/insert triples. We integrated it in Django reusing the database connection and exposing an ORM interface, along with full-text search on literals.

This presentation shows a Django-Rdflib case study with a PostgreSQL backend in Brain Architecture Management System(BAMS) - a neuroscientific project for the University of Southern California. Benefits of the flexible RDF structure will be shown, allowing researchers to insert free format data, making data public with a customizable serialization and use the powerful full-text search integrated in PostgreSQL.

Saving Gaia with jQuery Mobile, OpenLayers and GeoDjango

We had the privilege of working on a mobile web application for ETH Zurich, funded by ETH North-South Centre, using Django/Postgis, jQuery mobile and Openlayers technology.

In this talk, I would like to share what we have learnt technically and the experiences and fun we had with polygon creation on a map and saving polygon vertices and related data into our spatial database via geodjango.

This mobile web app is developed based on research by Dr Koh of ETH Zurich, specializing on Matrix-calibrated and edge-corrected species-area models that allow users to evaluate the biodiversity consequence and trade-offs of land-use decisions. The development and description of these models were published in Conserv. Biol. 24, 994 and J. Appl. Ecol. 47, 1063.
