Facilitating VLE - Library Integration using IMS Enterprise?

Project Objectives

● An overview of the findings from work undertaken within Strand 2 of the 4i project.

● This area of development focused on the development of technical integration methods to facilitate better interoperability between diverse systems and platforms.

● Institutional solutions implemented and recommendations for future standards developments are presented.

Session Overview

● Why integrate VLE and Library systems?

● 4i Project - a live use case scenario

● Benefits of metadata facilitated VLE - Library integration

● IMS Enterprise (& other) requirements

Why integrate the VLE & Library?

● All courses (traditional and virtual) require supporting resources

● Campus based students have ready access to the Library and all its services

● Remote users may not appreciate library services available

● Need to ease and integrate access to knowledge resources for all students (FT, PT & distance)

Project Stakeholders

● Academics / Students (learning experience)

● Librarians

● Information Services systems teams

● VLE vendors

● Library systems vendors

Drivers for Change

● Rapid roll-out of Distance Learning courses― Language and time zone issues*

● Changing student culture― Increasing demand for off campus library access by part-time

and full-time students*

● VLE courses - Library: well worn path

* helpdesk implications

Learner Benefits of Integration

● Promotes greater contextualisation by the learners (discovery v spoon feeding)

● Allows staff to reference quality resources from their courses in a managed way

● Learning increasingly taking place off campus - brings the library to the learners

● Increases awareness & utilisation of library resources and services

Opportunities for Integration● Course area - a natural library gateway● Within the course area, the users ID and course ID are

known (detailed profile available)● Additional course metadata may be available

(Department, School, Campus) - IF derived from course database

● VLE organisation model normally closed (programme, course, unit)

● Potential for single sign-on

A Live Use Case Scenario

UU Integration Objectives● Provide ALL UU (WebCT) module areas with:

― modular library perspective― contextual links to other library resources and services― seamless access to electronic resources (single sign-on)

● Initial pilot work involved collaboration with vendors― WebCT (institutional VLE supplier)― Talis Information Ltd (institutional Library system supplier)― Athens (national access management system)

● 2002/3 JISC DiVLE programme funded 4i project

4i Project Objectives

● Linking VLE’s with Digital Libraries: an integrated, interoperable, institutional implementation (4i)

― To assess the impact of institution wide VLE-Library system integration on library business processes and the user experience.

― To further develop technical integration methods to facilitate better interoperability between diverse systems and platforms and across institutions.

UU Library Requirements

● Engagement with Library staff identified three tiers of library links within WebCT course areas:― Institutional (library homepage)― Subject guides― Module Resources (Talislist)

● In addition:― Library Service Point – a gateway to further contextualised library

resource, service and support options.

● Further information on the technical development of the LSP is available

IMS Enterprise in Action

● UU WebCT integrated with Student Registry, Human Resources and Course databases via IMS Enterprise API

● Systems used - local, Oracle based● People, Group and Membership all utilised● Students fully managed - staff membership managed by

dedicated database.● Library data derived from similar source● Migrating to common data feeds

UU Integration Methodology

● Current Approach..― Cookie with user and course ID payload― Data shared via single point of integration― Library Service Point (LSP)

● Way forward..― Web Services approach!!

UU use of Implicit Metadata● Implicit metadata available from UU course ID schema● Typical UU course ID: abc567j1

― abc: subject code― First digit(5): year code (discriminates PG / UG)― abc567: course code― j: campus identifier― Final digit (1): semester identifier― Additional field available to indicate DL

UU VLE-Library Integration Demo

4 standard Library links within VLE

navigation options

Generic link to the main Library

website via LSP

Library Services Link● ‘Library Services’ offers dynamic contextualised links with

seamless VLE-Library authentication to a range of internal and external Library systems and services via the LSP: ― Main Library Website and Catalogue (generic)― My Module Resource List (module-specific)― Library Information & Services for My Faculty (faculty-specific)― My Electronic Information Services (Athens) (person-specific)― New additions to the Library in My Subject (school-specific)― Past exam papers for this module (module-specific)― My Library Account (person-specific)

Clicking here passes user and module ID to LSP that

generates a contextualised menu of Library resource,

service and support options.

Module Resources Link

Module resource lists are managed using the Talislist system● A standalone web-based resource list management system

that integrates with Library Management System.● Resource lists are structured and annotated as required● A CONTEXTUAL gateway through which internal and

external learning resources can be delivered.● Centrally managed by Library, with option to grant

academics editing rights.

Clicking here passes user and module ID to LSP; link to

appropriate Module Resource List (in TalisList) is automatically

generated.

TalisList: Clicking here opens the required subsection of the

Module Resource

External Library Resources:Selecting this e-journal from the

list of module resources generates a link directly to the article in

ScienceDirect using the Digital Object Identifier (DOI)

e.g. http://dx.doi.org/10.1016/S0006-8993(00)02382-9

N.B. Athens Devolved Authentication used to enable seamless access to external library resources off-campus

Subject Guide Link

● Organised on Faculty / School basis● Managed by Subject Librarians● Broader perspective than module resource lists - useful

for student research purposes● Provide some contextual support for students when a

module resource list is not yet available in Talislist

Clicking here passes user and module ID to LSP; link to

appropriate Subject Guide (in Library website) is

automatically generated.

Relevant Library news items along with a range of links to subject-

specific resources is presented to the user via drop-down menus

Interoperability Constraints of Current Approach

● Library integration achieved at course level.● Implications of this include:

― Managed at the designer level; difficult to deploy on institutional basis

― Changes must be done at the course level (1000’s of courses…)

― If exported to another institution, links still point to UU LSP

Benefits of Metadata Facilitated VLE-Library Integration

● Defined and managed at system level; Library can define integration institutionally.

● A number of integration strategies can be defined and implemented centrally.

● Course export issue avoided as integration parameter defined as the course instance is deployed (not part of Content Package manifest).

Relevant IMS Schema?

● Content Packaging? ― No. An undeployed course has no context (i.e. institution,

module code, campus etc.) to define any necessary library integration.

● Enterprise? ― Yes! This defines the deployment of a course instance. Further,

this definition includes relevant course data. ― Enterprise API is also the primary data management tool of

VLE administrators.― Proposal - use Enterprise to define and deploy library

integration at the course level.

Library Integration:A Special Case?

● Institutional integration to library environment is beyond the scope of a simple resource.

● To realise meaningful integration, additional course related data is required.

● Standard IMS Resource field not appropriate.● Dedicated LIBRARY data structure require.

Library Integration:Data Requirements

● What Library services (if any) are required?

● Where are these “library” services located?

● What information about the course is required to contextualise the presented library service?

● If multiple course data is required, is there a hierarchy?

Library Service(s)

● Example services identified by 4i project:― Specific Library webpages― Library Management System― Resource List Management tool― Library Gateway― Helpdesk

● Possibility - closed vocabulary!● N.B. suite of these likely to be required!

IMS Implications of Multi-library Service Requirements

● Within a Library element, we must be able to fully define each service.

● If Library integration is explicitly defined in underlying course metadata, a VLE could implement appropriate integration methodologies on a course by course basis across the institution.

Library Service Location

● As the aim of this work is integrating two web based services, the “library location” will be some form of web location, i.e. a url variable will suffice.

● Some use cases - external services - location must therefore be defined on a service by service basis.

Required Course Data to Facilitate a Given Service

● Depending on the availability of course data and the Library organisational model, the following course data could faciltate library integration― Course UID*― Department*― Subject area*― Campus*

● Required - which course metadata to use=closed list!* These are potentially available from existing course metadata

Is a Hierarchy Required for Multiple Data Based Queries?

● Some use cases (i.e. a campus and subject based query) are significantly improved if query is appropriately ordered.

● IMS implication - we must provide an option to define a hierarchy of service definition data elements

Possible Library Metadata Structure

Complex Course Provisions…Need for a defined “my home library”?

Should a Users Home Library Link be Defined in LIP?

● Emerging trends in e-learning― consortia courses― virtual electives

● Such learners have multiple library associations● In many cases, learner may be best supported by their

local (home) library.● To inform and promote this option, should a learner’s

home Library URL be defined in LIP?

IMS Implications

● Enterprise● Enterprise Services● LIP?

Conclusions

● Integrating the library to a VLE course is preferable to integrating resources alone.

● IMS Enterprise - ideal to define library integration

● IMS Enterprise schema lacks an appropriate structure to achieve this.

● A dedicated Library data structure is necessary.

● Potential benefit of defining users home Library in LIP?
