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.

    Service-Oriented Architecture for Libraries Service-Oriented Architecture for Libraries Presentation Transcript

    • Service-Oriented Architecture for Libraries Richard Akerman NRC CISTI presented at DLF Fall Forum November 6, 2007
    • Who Are You?
    • What Do You Want?
    • CISTI EA - Infomajic Business Framework IT Architecture Framework •Tightly link the Framework for Implementation 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 & design on the architecture by permission of Jane Carbone, Infomajic 4
    • Why Are You Here?
    • Where Are You Going?
    • Transformations • Digital • Internet • Discovery • Exponential • Library? 7

    • How Do You Get There? Business Framework IT Architecture Framework •Tightly link the Framework for Implementation 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 & design on the architecture by permission of Jane Carbone, Infomajic 14
    • 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 15

    • 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
    • Deriving SOA Services • Developed litmus test to evaluate business functions in terms of SOA characteristics • 14 SOA services have been identified and implemented 19
    • 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 20
    • SOA Services 21
    • Projects • Pay Per Article (PPA) • eBook Loans • Alerts • Reduced effort due to building on SOA services frees organisational resources for agility 22
    • Experiments • SRU/SRW • CISTI Lab http://lab.cisti-icist.nrc-cnrc.gc.ca/ 23
    • SOA and Digital Libraries • DELOS http://www.delos.info/ • Fedora Commons http://www.fedora-commons.org/ 24
    • 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
    • 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 model http://www.sciencemodel.net/ 26
    • Building Bridges 27 © 2001 Richard Akerman
    • SOA Governance • Service identification & specification • Service implementation • Service exposure • Service usage & cost allocation • Service change management • Governance roles 28
    • 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
    • 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
    • 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
    • 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? 32
    • Wherever You Go... There You Are • Richard.Akerman at NRC.ca • http://www.connotea.org/user/scilib/tag/dlf2007akerman 33
