mapping the wireless revolution on the semantic web

semantic web spatial modelling

collaborative mapping

MUD world isomorphic to our own

RESTful RDF interface

Jabber/IM bot frontend

wandering round the City of London with a jabber bot

noderunner, a wireless mapping game originally played in New York

played in london on may 15th at the Cartographic Congress in limehouse

scan, photograph yourself at, and connect to as many open wireless nodes as possible

between 2 points, at a set time, against other teams.

gathering GPS waypoint data and scanner logs

each player is a foaf:Person and a noderunner:teamMember of a team

we can use foaf:mbox as a unique identifier (InverseFunctionalProperty)

an RDF model for a noderunner game

as the team moves about, it collects pictures, which annotate points in space (latitude and longitude)

a team's route during a game, modelled in RDF

some of these are in XML!

we wrote XSLT and XML::XPath to do this

there is a RESTful interface for playing noderunner via the web

this consists of a lot of functions like 'add_team', 'show_route_for_team', 'add_point_to_route'

you can POST updates to the web interface, and GET RDF or SVG descriptions of things.

using other RDF web services to find out more - postcode, OS grid

collating together the graphs, and reasoning about the bigger graph

RDF graphs using a wireless ontology can be annotated with space and time

now we have some annotated spatial data

waypoints displayed in SVG

if only they could be projected on a free map.

a GPS waypoint log modelled in RDF

a model of the wireless network world that sits on the physical world

an annotation and assistance layer for the physical world, available through the wireless network
