3. Workforce realingment
Introduction
uPortal implemented 2002
Replacement for existing user interface to applications & services
Largest audience was students
Workforce realingment

4. Support our changing business model

Support our changing business model
Employees do not stay in one system all day
Service Centers
Lower administrative costs
Improve efficiency & productivity
Lower training cost - tools in one place
Improve Communication
Provide visibility to process state
what happened to my purchase request?

Portal: a user-centric web desktop that gives users access to all of the information resources they commonly use.
Workflow Service: General purpose service that automates the routing of documents to the users responsible for working on them.
Notification Service: General purpose service where any authorized application or user can reliably notify a user of a task, an alert or an event.

Currently lists of links
How can we add more functionality

7. uPortal usage
The more content we put there the more people will use it; the more they use it the more content providers will want to provide rich content

8. Workflow
Kuali Enterprise Workflow
A major hook for Administrative users
Action list in the portal
If people are already looking at their action list, can we add even more value?

9. Notification portlet A superset of the Task list
A single place to see all your tasks, events & alerts
Your style of portal use
Constantly connected
Occasionally connected
Unconnected
How to get your attention
Tickler & Preferences
The portal is where you go to deal with notifications

10. Kinds of Notifications
Something you need to do
Workflow
Something you need to know
Push to a targeted audience
Something you want to know
Requested notifications

11. Technical Goals Architectural (SOA) Collaborative Development
Standards
Pluggable components
Reusability
Collaborative Development
Access campus technical resources
Gain experience with collaboration technologies
Video & Web conferencing
SourceForge® Enterprise Edition
Engage other interested parties early in the development process

Workflow
Kuali workflow - most application need some kinds of workflow/approvals
KEW was originally designed to meet this need - different that commercial products
They solved this problem a while ago - this is want is needed for applications like Kuali finance
Jus as Cornell got involved IU was also see a need for a light weight client (not a java application)
EDL was born
Move towards the enterprise service buss

Open Knowledge Initiative (OKI)
Open Service Interface Definition (OSID)
Technology agnostic service definitions
Authentication, Authorization, Agent, Logging
The Open Knowledge Initiative (O.K.I) develops and promotes specifications that describe how the components of a software environment communicate with each other and with other enterprise systems. O.K.I. specifications enable sustainable interoperability and integration by defining standards for Service Oriented Architecture (SOA). Through this work O.K.I. seeks to open new market opportunities across a wide range of software application domains.
Open Service Interface Definitions (OSIDs), whose design has been informed by a broad architectural view. The OSIDs define important components of a SOA as they provide general software contracts between service consumers and service providers. This enables applications to be constructed independently of any particular service environment, and eases integration. The OSIDs enable choice of end-user tools by providing plug-in interoperability.
OSIDs are software contracts only and therefore are compatible with most other technologies and specifications, such a SOAP, WSDL. They can be used with existing technology, open source or vended solutions.
OSIDs are a local language service definition and bindings of them are provided in Java, PHP, and soon Objective C and C#.
