overview
motivation: current issues the library portal services: a changed perspective service-oriented technology
libraries learning research
issues for planning

motivation: current issues
moving from a centralized access system to multiple distributed systems
increased availability of information from multiple resources
library services are often bundled based on library infrastructure
the user is responsible for understanding the history and operation of the library

motivation: current issues
“There is a growing acceptance that simply making resources available without an additional level of services may not be very effective”
(McLean & Lynch p.3)

the library portal
a software suite that provides users with customized access to information resources and tools
a continuum of strategies that provide a range of integration levels ‘p-portals’ provide integrated access to
content at the user-interface level ‘m-portals’ provide integrated access at a
programming level

m-portal framework allows services to be presented to the user at a more meaningful level of abstraction (e.g.): allows libraries to design services that require multiple interactions with numerous services simplifies and unifies the presentation of information for users provides a means to move information between library systems and services

services: a changed perspective
“It is sometimes suggested that content is king, that the major imperative is to make collections available”…
“Appropriate services make our collections come alive”
(Dempsey p.28)
![Page 10: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/10.jpg)
services: a changed perspective
current systems typically organized around data resources
the integration layer can allow us to reorganize our systems to better support user services
![Page 11: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/11.jpg)
services: a changed perspective
Two types of services: services that directly support the user services that support other services

service-oriented technology
On integration of information and learning environments:
“This approach requires a conceptual shift away from a traditional systems architecture viewpoint to one where applications become defined by the service provided and the services that can be accessed.”
(McLean & Lynch p. 14)
![Page 15: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/15.jpg)
service-oriented technology
NSF Cyberinfrastructure specifies a service layer that includes: Data, information, knowledge
management services Collaboration services

services that are used by many systems (e.g., institutional, national) to improve services terminology services collection and service registries authentication/authorization services

terminology services
services that provide alternate terms that can be used expand a search
experimental and limited in scope at this time
![Page 20: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/20.jpg)
collection services
registries that share information about collections and services
most effective if machine level integration is available
currently registries of Z39.50 services exist
the focus of a NISO metasearch study group
![Page 21: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/21.jpg)
authentication/authorization
authentication: verifies that you are who you say you are
authorization: determines if you are allowed to use a resource
single-sign-on: a methodology for passing your credentials so that all systems know who you are
![Page 22: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/22.jpg)
identity management
identity management provides a framework that allows authentication/authorization information to: be administered have common definitions of attributes provide a mechanism to ensure privacy allow multiple trust relationships
shibboleth is an example for universal access it will be necessary to develop
and use (international) standards the focus of a NISO metasearch study group
![Page 23: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/23.jpg)
issues for planning
identify services (applications) that are important to users
identify generalizations of common services (tools) that support other services
conceptualize library technology as an integrated whole
![Page 24: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/24.jpg)
issues for planning
integration services simplify access for users automates system to system communication uses information about the user to make
decisions standards are emerging but not sufficient there is an enormous amount of new
configuration metadata that must be developed to hide complexity from the user
![Page 25: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/25.jpg)
issues for planning
Examples of configuration metadata: metasearching:
collection description result set mapping
link resolution mapping citation information to OpenURL mapping OpenURL to target URL creating display ordering rules etc.
![Page 26: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/26.jpg)
issues for planning
without the presence of robust standards integration is expensive and time-consuming
understand the configuration that will be required and determine who is responsible for maintenance
![Page 27: Library Technology](https://reader035.vdocument.in/reader035/viewer/2022062314/56813a68550346895da25ff8/html5/thumbnails/27.jpg)
