Description of motivation for Enterprise Architecture, transformational challenges facing libraries as the move into the digital environment, thinking about software architecture, my organisation's specific context, and how SOA fits in to it all.

Framework
•Tightly link the Framework for

architecture to
the business
Projects
•Use an approach
that is disciplined Metrics
(repeatable) and
Analysis,
Buy-In
traceable back to
Design &
the business Process Development
People
•Develop an action plan to
support implementation •Architecture outputs are
integrated with each other and with
other IT outputs – Base analysis &

15. Teamwork
• CISTI has a staff of over 300, serving the
National Research Council and thousands of
other clients
• We have in-house technology and research,
with a staff of approximately 60 total, of
which about 30 perform software
development and research
• There is a 5-person Architecture Group

20. SOA Definition
• Service-Oriented Architecture is an
approach to systems analysis
- a systematic methodology for identifying
particular characteristics of business
processes and technology, leading to the
definition of “SOA services”
18

21. Deriving SOA Services
• Developed litmus test to evaluate business
functions in terms of SOA characteristics
• 14 SOA services have been identified and
implemented
19

22. SOA Services
• “autonomous, loosely-coupled and coarse-
grained services with well-defined interfaces
provide business functionality and can be
discovered and accessed through a
supportive infrastructure. This allows
internal and external system integration as
well as flexible reuse of application logic
through the composition of services.”
- Malte Poppensieker

24. Projects
• Pay Per Article (PPA)
• eBook Loans
• Alerts
• Reduced effort due to building on SOA
services frees organisational resources for
agility
22

25. Experiments
• SRU/SRW
• CISTI Lab
http://lab.cisti-icist.nrc-cnrc.gc.ca/
23

26. SOA and
Digital Libraries
• DELOS
http://www.delos.info/
• Fedora Commons
http://www.fedora-commons.org/
24

27. SOA and
library catalogues
• When improving the catalogue, we must
take care not to repeat the past
• SOA provides an approach to enhancing the
catalogue that is sustainable
• SOA also opens up the possibility of greater
WebOPAC and network capabilities
(mashups, widgets, machine-to-machine
services)
25

28. SOA and
Cyberinfrastructure
• New NSF calls
• Cyber-Enabled Discovery and Innovation
• Sustainable Digital Data Preservation and
Access Network Partners (DataNet)
• The Scientific Communication Life-Cycle

30. SOA Governance
• Service identification & specification
• Service implementation
• Service exposure
• Service usage & cost allocation
• Service change management
• Governance roles
28

31. Challenge: Frameworks
• There are many frameworks and reference
models
• JISC (UK), e-Framework (UK & Australia),
DLF (USA), CDL (California), DEFF
(Denmark), DELOS (EU), ...
• How can we best use frameworks?
29

32. Observations
• SOA must move beyond frameworks
• SOA Governance is key
• The “Big Bang” approach doesn’t work
• Creating an SOA (and EA) is not for
everyone
- but everyone can participate as a
service consumer
30

33. Enabling Library SOA
• “Library Web Services” in Library Journal -
netConnect, July 15, 2007
• “Service-Oriented Architecture - What Is It,
And How Do We Get One?” in EDUCAUSE
Quarterly,Vol. 30, No. 3, 2007
• “Web Services and the Service-Oriented
Architecture”, Library Technology Reports,Vol.
42, No. 3, 2006
31

34. Questions
• What gaps can be filled with a services
architecture?
• How can we move beyond frameworks?
• What is the relationship between the library
catalogue, digital libraries, and repositories?
• Are people using architecture, including the
DLF work? Why or why not?
