Science ecosystems
• These elements are what enable scientists to
explore/ confirm/ deny their research and
collaborate!
• Abduction versus induction and deduction

How far to go - Humatics
Penultimacy
 Platforms assembled from frameworks; they must look
more and more like a commodity (your phone) to how
you work
 6th generation of mediation – not more computermediation but smarter computers and lots of people
 Data as infostructure; mixing knowledge, information and
data for consumption
 From virtual observatories to linked virtual observatories
 From the Deep Carbon Virtual Observatory to the Deep Earth
Computer in say 8-10 years.
 From this and related sessions, it seems ‘we’ are going in
the right direction

Prior to 2005, we built
systems
• Rough definitions
– Systems have very well-define entry and
exit points. A user tends to know when
they are using one. Options for
extensions are limited and usually
require engineering
– Frameworks have many entry and use
points. A user often does not know when
they are using one. Extension points are
part of the design
– Platforms are built on frameworks 17
