1. Kuali Enterprise Notification Tell Me What I Want And Need To Know Aaron Godert (Sr. Software Architect, Cornell University) John Fereira (Programmer/Analyst, Cornell University)

2. Introducing KEN Kuali Enterprise Notification (KEN) provides a single list for all university related communications –Workflow items (KEW) –Non-workflow items (KEN) Examples of non-workflow items: –Your book is overdue –A concert is coming up on campus –Graduation check list to all Seniors

3. A Single “Action List”!

4. A Kuali Rice Component There are several middleware components that make up Rice KEN is one of them Each component works with the others to provide complementary technical functionality

6. A Communication Broker

7. Functional Goals Eliminate sifting through email Quickly find what you need, to go about your university related business Provide a controlled environment –Eliminate unwanted messages, prevent duplication –Integrated user and group management Audit trail Centralize communication broker More robust preference and searching capabilities

8. Functional Requirements Three types of notifications: –1.) Things I have to do Electronically (online) - KEW Manually (physically) - KEN –2.) Things I need to know about “School is closed - Snow Day!!!” –3.) Things I want to know about “Dr. Nobel Laureate is coming to speak to the Computer Science club on…”

9. Functional Requirements Target groups of people and specific people Control delivery dates Notifications automated by systems - s2s Manual entry of notifications - generic message form Event notification –Integration with personal calendars Multiple delivery end-points –Email –Text message to mobile phones

10. Technical Goals Adhere to SOA principles Develop collaboratively using the Community Source model Build using standard Open Source J2EE technologies Re-use technical products in Kuali

11. The Architecture

12. The Design

13. The Tools Java SDK 1.5+ Spring Framework –Service interface and implementations –Spring MVC Apache OJB –Object relational mapper McKoi DB (evaluating Apache Derby) –Quickstart Start with Oracle DDL (evaluating Apache DDLutils) –Production

14. The Tools OpenSymphony Quartz –Spring integration Apache Tomcat 5.5+ JSP/JSTL XML/XSD –DOM/Xpath –XStream XSLT Apache Axis

15. Sending a Notification: s2s Java API - Java services (injected using Spring) –POJO in and POJO out Notification n = new Notification(); n.addRecipient(“TestUser1”); … NotificationResponse response = notificationService.sendNotification(n); –String in and String out (XML) String notificationXml = ; String response = notificationService.sendNotification(notificationXml); Web service invocation –String in and String out (XML)

16. A Notification Request as XML

17. Content Types Two content types provided out-of-the-box: –Simple –Event

18. Flexible Content Types To add a new content type: 1.Write the sample XML for inside of the tag 2.Write the XSD to validate your content type 3.Write the XSL to transform your content type during rendering 4.Add a new record to the “Content Types” table - (name, description, active/inactive, XSD text, XSL text)

19. Flexible Delivery Endpoints Not yet built Java interface to implement –Specify properties that would get set by a user in their preferences –Property values would be used to actually deliver the message Mobile phone # Email address –Implement the “deliver()” method Call out to an SMS API Call out to an Email API Delivery will be asynch - wire up a Quartz job in Spring

20. Kuali Rice Integration

21. KEW Integration Action list –KEW already has the concept of an action item User and group management –KEN’s recipient service is implemented by calling the KEW user and workgroup services –Common set of users and groups for both applications Logging –Notifications become action items, action items get automatic logging EDocLite (EDL) –Our generic notification message sending form is an EDL –Positioned for workflow approvals of messages

22. KSB Integration Exposing the Java service “sendNotification()” directly on the bus –HttpRemoting over SSL –POJO (serializable) input/output Exposing as a WS on the bus using the generic web service feature of KSB –I don’t have to touch Apache Axis! –Implement a KSB Java interface Responsible for translating XML (String) to POJOs –Wire up the call in Spring with approximately 10 lines of XML

23. KNS Integration Not yet integrated Maintenance document features –Dynamic rendering and persisting of administrative reference tables Adding/updating/deleting Notification Producers, Notification Channels, Content Types, etc Automatic workflow integration Automatic versioning of records

24. Features in 1.0 Send notifications via s2s API/WS calls; users can also send via message form (EDL) Users will see their notifications alongside of workflow items in a more general action list –Within the list, users will be able to: Search for by channel, type, producer, sender, and priority Save searches for later use Take action on notifications (clearing/acknowledging) Click on notification to see more details about the notification View a log for the notification (who, what, where, when, why)

25. Features in 1.0 Users will be able to set up multiple delivery end points or “ticklers” –We’ll come OOTB with an email tickler Flexible content types (XML/XSD/XSL) Basic authorization - Notification Channel to Notification Producer mappings CAS end user authentication SSL for transport of anything over HTTP (WS/web app) User and group management

26. Status of 1.0 Features Basic features are in place –Can send a notification s2s and through a generic message form Basic KEW and KSB integration complete –Notification messages are showing up in the single action list –Basic logging, searching, and preferences are in place –EDL form for sending messages Still need to: –Build sample clients in various technologies to test –Build multiple delivery end point framework –Tweak action list, logging, searching, and preferences to be more generic and less workflow specific

27. Future Features SMS delivery end point JSR Compliant Portlets –Action list –Preference management KNS Maintenance documents for administration Attachments iCal integration for event types s2s revocation of notification messages Ability to schedule recurring messages And more…

28. Time Frame for Deliverables 1.0 - April 2007 1.X+ (future features) - aiming for 3 month cycles Kuali Rice bundling - Summer 2007
