BarCamp London 8: giffgaff - getting what you want from Mobile network APIs

Heather Taylor @giffgaff & Vincent Boon @vincentboon

• starting to open APIs
• giffgaff is:
  • SIM only
  • 100% online
  • mutual — give & take
  • no call centres — only 16 full time staff!
• “goodybag” data is currently completely unlimited, no fair use policy!
  • have agreed a charge with community for when they do start to charge
• customers generally get an answer from community in under 3 minutes!
• current plan for APIs (steps 1 & 2 pretty much done!):
  1. info services: read-only >
     • balance
     • goodybags
     • points
     • call records
  2. get services:
     • order SIM
     • top up
     • purchase goodybag
  3. non giffgaff
     • status update
     • share links
     • email/SMS
• working with O2 Litmus and HashBlue guys to integrate their work (giffgaff is an MVNO on top of O2)

BarCamp London 8: wheelmap.org

Holger Dieterich — @holgerd

More details on lanyrd

• http://wheelmap.org — find wheelchair accessible places to eat & drink
• Made by http://sozialhelden.de — Social Heroes
  • one of the founders is in a wheelchair
  • problem is not how to get somewhere, but how to find somewhere suitable
  • is there a step? is the toilet accessible?
• databases in Germany have 30,000 places, but they’re not so easy to use (mostly commercial)
• had a wheelchair tag in OpenStreetMap before they started, but only about 5,000 places were tagged
• now have about 18,000 places in germany
  • 300-400 places edited a day!
• website finds your location by IP and offers you places to edit/add
• also an iPhone app
  • using OpenLayers to display
• CloudMade is good, but is read-only and not updated regularly (once a month!)
  • want to have immediate update
  • don’t yet have immediate, but 3 minutes is close
  • OpenStreetMap itself is sometimes down (for three days at one point), so had to implement caching and their own intermediate API
• also approaching companies to share their data…
  • they’re really scared… so talking with Berlin government to convince them
• having slight issues with OSM community as wheelmap data is added anonymously by a pseudonymous user
  • but it’s better that data gets added
  • and there’s no real chance of spam since the data is added automatically
