Background/Goals for IMS ES v2

• IMS Enterprise v1: public release 2002• IMS Enterprise Services v1.1: public release

2004• V1 specs were too generic – resulted in non

standard integrations• Needed more defined structure for Course

Management • Wanted more granular Outcomes model• Wanted to harmonize Person definition with IMS

Learner Information Profile (IMS LIP)

Customer Needs

—Near real time integration

—Course to course site mapping (multi-section and

cross-listed courses)

—Final grade reporting

—Support for adjunct solutions (e.g., course

evaluations, external wikis, etc.)

—Lower and more controlled integration costs

Goals for IMS ES v2

• Relationships between courses/sections

• Enhanced Grade/Outcome model

• Better handling for multi-sectioned and cross-listed

• Increased adoption by SIS and LMS vendors

(Enterprise Alliance)

• Room for growth into other integration use cases

Profiles & Conformance

• Ability to add constraints to base

specification

• Ability to define specific vocabulary for use in

specification

• Conformance will be tested against profile



14

SAIP v1

• Oracle has chosen to implement IMS ES v2 for SAIP using Sakai

as a reference (SAKORA Project)

• Focuses on mission critical integration of SIS and LMS

• Web services provide flexible, comprehensive batch and real

time integration

• Online functionality for easy, flexible default and ad hoc scoping

of courses and course to course site mapping

• Inbound Final Grades/Outcomes

• LDAP Binding to support provisioning to non-services based

solutions



15

Sakai Touchpoints

• CM API

• User provider

• Gradebook

• Profile tool?

• Others?
