Consuming open and linked data with open source tools
This document discusses consuming and using open and linked data with open source tools. It outlines the available data and distribution technologies like RDF, SPARQL and linked data. It then explains the typical software stack used including tools for querying, storing and visualizing the data. The document provides an example of actually retrieving data and doing something useful with it. It also notes some potential issues or "gotchas" and provides further resources for working with open data.

- 25. Conclusions A dash ofall these, some readily available python libraries, and some relatively simple scripting gets you useful data for your own applications... ... and by using PostgreSQL to store your data, you can provide a buffer in case of api changes or outages... ... and even do some nifty manipulation to analyse and present the data differently!
