+This hack is really just a programming excercise :-)
+
+What data: The List event 2012
+
+What I've done with it
+---
+- I've written a Haskell program that...
+- Transforms the XML into RDF
+- Defines a schema for The List specific fields
+- Reuses ontologies for field e.g. location (wg84pos)
+- Serializes the RDF into the Turtle file format
+
+In addition...
+- The program goes out to to the The List web API to grab more info
+about locations
+- Goes out to Linked Geo Data and discovers the nearby pubs to the
+venue (within 100 metres)
+
+
+Why?! have I done it?
+---
+- Linked Open Data is *really* awesome.
+- It'd great to have The List on the cloud of linked open data
+- ... on this map: http://richard.cyganiak.de/2007/10/lod/
+- (More exposure on the semantic web for The List events!!)
+- Venue location info is disambiguated, so all kinds of interesting
+information can be sought from the semantic web (finding pubs is just
+a proof-of-concept).
+
+Files
+---
+- list_mappings.hs <- the Haskell code to generate the turtle file
+- list.ttl <- the file generated
+- README <- this file
+
+
+What next?
+--
+- You can install a SPARQL endpoit.. point it at the .ttl file, and
+you have a *semantic search endpoint* for free out-of-the-box.
+- Get in touch with me.. I'd happily add more (robstewart57@gmail.com).
