The final day of The Open Group Architecture Practitioners Conference
in Budapest, Hungary introduced six targeted streams containing a
variety of presentations and workshops. Wednesday’s streams included:
Architecting Trust; Information Architecture; Enterprise Architecture
Case Studies; Securing your SOA Environment; Service Oriented
Architecture; and Business Architecture.
In the Architecting Trust stream Arnold van Overeem, Capgemini,
spoke about "Architecting Trust". Arnold argued that trust
relations are unidirectional, explored what makes someone trust other
individuals, and provided a detailed analysis of "trust
relations". He also provided two definitions of identity management
and presented the pros and cons of each definition.
Ron Schuldt, Lockheed Martin, conducted a workshop on information
architecture for SOA, specifically inviting the audience to weigh in on
whether or not the industry and architecture practitioners would benefit
from the introduction of an information architecture reference model. He
also discussed the SOA semantics problem and solicited attendee feedback
on concepts presented and next steps.
Within the Enterprise Architecture Case Studies stream, Dennis
Kerssens, Getronics, presented a case study called
"Architecture – More than a Toy for the Architect". Dennis
gave details on recommended ways to anchor TOGAF™ in the business
planning cycle. He took the position that enterprise architecture should
ideally be an Initiative in the top management, be comprised of a mix of
aspect and discipline, and that only results count, among other things.
K. Scott Morrison, Layer 7 Technologies, as part of the Securing
your SOA Environment track, spoke on federating identity in SOA. Among
other things, this presentation included definitions of identity and
federation, perspective on the fundamental challenge in distributed
computing, and posed the question: does this mean that people should use
infrastructure for web application SSO (which is mature and widely
deployed) to build federated SOAs?
Dave van Gelder, Capgemini, gave Business Architecture track
attendees an introduction to and report on the Business Architecture
Work Group followed by an in-depth presentation on Business Architecture
Work Group terminology, which was then followed by an interactive
discussion on the information presented in the sessions.
