Information landscape
Topology of the common information environmentSee AKM9, 2005, Porec (!)Seamless, joined-up services and widest range of

Granularity and lumpiness
More granularity = finer detailsmoother landscape
easier, flexible navigationuse statements to navigate
Need more than one statement to identify and select a resource
set of statements = record
Ground zero = Chain reaction
