Yahoo! Open Location
• Creating an Open Infrastructure for a LocationAware Internet:
– Open Ownership: control and transparency
– Open Exchange: avoid ‘roach motel’ mentality –
locations accessible across apps/devices/platforms
– Open Platforms: easy to use, accessible
– Open Data: using the same grammar and vocabulary
to describe named place geography
• Part of the Y!OS initiative
• Open = Ethos and Product
