Service-Oriented Architecture for Libraries

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

Model_____ 16

Model - Ingest 17

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

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
