Why EASYCOMPs Technology is
Most Suited for AmI
AmI applications must have an architecture (a composition)
Easier to integrate, update, negotiate, also dynamically
Documents and software can be treated uniformly
Europe has developed the basic technology, it must be
transfered to a larger community
EASYCOMP is leading world-wide
2nd generation aspects (event-based aspects)
Software composition systems, and others
EASYCOMP's composition technology must be broadened to
more dynamic architectures
EASYCOMP's advance can create a leading edge of 5-7
years in Ambient Composition

Strategic Investment Into Base
Markets Makes the Difference
Composition Systems are the new base market for AmI
Win a base market, and the application markets will be yours
Similar to office systems or business systems
Not yet clear, who will win it -- Europe or US
[3rd FW Project COMPARE: The CoSy story]
ACE b.V, Amsterdam, conquers the compiler market by a
more strategic market, compiler frameworks
A strategic investment could gain the base market
But must be built on component and composition technology
HERE IS THE OPPORTUNITY!

Documents will be active (active documents)
Uniformly based on XML, the ASCII of the 21st
century
Tags will have active semantics <if> <then> <else>
Active Documents will penetrate
The future Web,
Future documents, and
Future software
Vision stems from [Orfali/Harkey: Instant CORBA]

New Base Market for Composition Systems
[3rd FW Project COMPARE: The CoSy story]
A strategic investment of 40 Mio Euro could gain the base
market (see DAML initiative)

Win a base market, and the application markets will be yours
Similar to office systems or business systems
Not yet clear, who will win it..
Strategic Investment Makes the

But even an IP could be very good.
