RE: [TF-DI] Discovery Categories and Tech Landscape

Soumya, Dave,

Again, thanks for your input. I edited the wikipage and incorporate your comments and hints into the set of discovery categories. I also added a new category for peer to peer discovery.
Please don't hesitate to adjust the wikipage if you think of some missing technology!

Dave, you mentioned discovery approaches incorporating relationships between people and things. Can you point us at links explaining this in more detail?

Thanks,
Arne

@Dave, could you illustrate how social relationships could act as enabler of discovery?

@Arne, I think discovery based on barcodes etc. should be another category for the tech landscape.
