Software and new approach in standardization
Middleware
– The engine of convergence is Software
Software
– Improve dynamic approach of products
– Dominant culture in Labs
New order in priorities
– Priority for players is to develop as quick as
possible systems, components, products
– …then to make them interoperate

Question : How
users understand
Open Standards?
… and Open source
Open standard is more and more
understood by users as “Open the code”
New challenge for Players :
– Integrate the new dimension of FREE and OPEN
– Open Source : What’s the business model ?
Open Source Software
– The biggest challenge that players and
SSOs are facing?

Open Source Strategy
Business strategy
Service
- To develop service using GPL or
other existing OSS component
- To develop own “OSS”
architecture
- To promote openness
- To develop ad-hoc architecture
and software to costumers
- To reinforce the critical
relationship with the costumers
Product
- To develop specific component
integrated in a proprietary product
- To promote theses components
within the OSS communities
- To strengthen the position of
the product on the market
- To benefit of OSS communities
assessment
Integra
-tion
- To develop Open Source
Enterprise architecture
- To develop service using their
own architecture mixed with others
(OSS or not)
- To promote their own
architecture included components
within the OSS communities
- To appear as federator
- To strengthen their position on
existing customer base
- To take an overall commitment
on the evolution of enterprise IT
systems

SSOs talks about
interfaces
SSOs are legitimate in
representing the common
interests of players and users
SSOs work on
component
SSOs challenge « technology
neutrality »
SSOs accept a software
code to define an
interface
- SSOs admit as relevant this
easiest way to proceed
- SSOs recognizes that a
component can be accepted as a
way to define an interface
SSOs accepts to work on
software code in the
standardization process
they get involved in debates on
software issues
Communities ask for
Open Standards
they ask to open the code on
which the standards are based on

Open Standards and Open Interface
Interfaces must deliberately
concentrate efforts
More and more formal description
of interfaces (SDL, ASN1, UML …)
Let the implementation to players
or consortia
More attention to Standards
profiles to address complexity
