8. Key Challenges
y g
for model, structure and knowledge
• C
Can our chemically‐inspired computation model and the
h i ll i i d t ti d l d th
eco‐laws?
– Be flexible and general‐purpose enough?
g p p g
– Effectively deal with the complexity and diversity of modern
pervasive scenarios?
– Be effectively implementable?
Be effectively
• And, for structure and knowledge
– Can it accommodate all needed distributed aggregation and
self‐composition algorthims
lf iti l thi
– Can it express all needed forms of knowledge management?
• Or should we rather go for application‐specific (or location‐
Or should go for application specific (or location
specific) eco‐laws?

9. Infrastructure and Applications
Infrastructure and Applications
• I f t t
Infrastructure
– A very lightweight infrastructure
– Ruling all interactions (from discovery to data exchange and
synchronization) by embedding the concept of eco‐laws
h i ti ) b b ddi th t f l
– To most extent, acting as a recommendation and planning engine
– Possibly inspired by tuple space coordination models
– Yet made it more “fluid” and suitable for a pervasive computing
continuum substrate  not a network but a continuum of tuple spaces
• Applications
– The “Ecosystem of Display” as a general and impactful testbed
– To put at work and demonstrate the SAPERE findings
p g
– Active and dynamic information sharing in urban scenarios
– Active participation of citizens to the working of the urban infrastructure

10. Key Tangible Results
y g
(hopefully)
• A novel model and methodology to support the development
of complex service systems in open and dynamic pervasive
scenarios
• A uniform set of:
– Self‐* algorithms for service/data composition and aggregation (in
the form of libraries)
th f f lib i )
– Algorithms and tools for distributed management of contextual‐
knowledge, to enforce present‐ and future‐awareness in the
ecosystem
• A novel middleware for pervasive computing scenarios (Open
Source)
)
– Integrating the stated algorithms in the form of libraries
• A set of released innovative application showcased on the
Ecosystem of Displays testbed
