Integration Between “Things”™ - with a Catch

Background

• Initially PeopleSoft extracts were IMS Enterprise 1.01 Vista 3 was IMS Enterprise 1.1

• Needs in our SIS did not match the needs in our LMS

• More need around campus for enrollment data

• Constant development since 2008

What’s wrong with direct Integration

• Data in your SIS is not Life in your LMS– Incompletes– Guests Lecturers– Cross Listed Classes (What a mess)– Name Changes– Anything else you can think of!

Basic Overview

Export Logic Import

Technical Details

• Originally written in Java ported to Python• “Event”/Snapshot based• LMS Enterprise 1.1 Based• Oracle Backend• Multiple Destinations

Inbound Sources

IMS Enterprise Based ObjectsLIS before LIS?

IMS XML Extract

PeopleSoft

LIS Soon?

No Idea!

Business Logic

IMS Enterprise Based Objects

Business Logic

Update Local Database Apply “Override” Information

Outbound Sources

Internal Database

Classes.nau.edu

iTunesU

IMS XML

Vista Web SIAPI

Bb Web Services

BBLearn SOAP/WS-

Security

Internal Web

Services

Push Tool

IMS Objects

• Objects– Group– Relationship– Properties– Membership– Member– Bulk load

• Methods to get override values(default) and underlying values

DB Schema

• LMS_GROUP_INFO• LMS_MEMBER_INFO• LMS_ENROLLMENT_INFO• LMS_DESTINATION_INFO• LMS_OVERRIDE_INFO

– TABLE_NAME– TABLE_ID– FIELD– VALUE

Web Service Integration

• Vista – Multipart IMS XML Web Upload to SIAPI

• BBLearn 9.1– WS-Security SOAP requests to API– Using Internally Developed BbPy Web

Service Bindings

Conclusion

• There is a need to control every field of data from the SIS to the LMS

• Distil all sources to common data sources, IMS Enterprise Spec

• Separate inbound and outbound data• Hopefully LIS will help the connections• Allows for future expansion
