- 4. What is this talk about? • Enterprise Portals • As the user interface – for your • Services Oriented Architecture
- 5. SOA? • Services oriented architecture • Around what services is the architecture oriented?
- 7. Formal Web Services • WSDL • SOAP • UDDI • WS-Security • WS-* http://www.flickr.com/photos/ennor/ 353215962/
- 8. Example: MyCourses • Sakai Web Services • MyCourses Portlet
- 12. Standards and Interoperability • LISv2 SIS LMS SIS integration? • Sakora
- 13. SOA - Services • Self-contained units of functionality • Reusable • Stateless • Loose coupling • Interoperable • Discoverable • Orchestration
- 14. Services in the Wild http://www.flickr.com/photos/zenera/ 1613856609/
- 15. Services exposed (or exposable) • Systems and web applications already expose oodles of lightweight services • You can easily make them expose more lightweight services • Probably more easily than getting the applications to expose formal web services? • WOA?
- 17. What exposes RSS? • Email lists • News sources • Social networking sites • Wikis and websites • Change logs • What doesn’t expose RSS?
- 18. iCal / xCal feeds http://www.flickr.com/photos/malabooboo/ 2405993368/
- 19. What exposes calendar feeds? • Google Calendar • Conferences • SIS modeling of course schedules • LMS modeling of course meetings • Event calendars (e.g. Bedework)
- 22. What exposes XML? • What can you convince to expose XML?
- 23. What generates email? http://www.flickr.com/photos/sirstick/ 76498325/
- 27. Announcements / Alerts !
- 28. How users interact with services? • Google • Thunderbird etc.
- 29. Consuming iCal Feeds in Google
- 31. Enterprise Portals • Aggregate Content & Applications • Customization & Personalization • Access Control • Consistent User Experience
- 32. Aggregation • View or path to everything in the Enterprise (content, applications, services) – Simple deep links to websites – Dashboard-style display of services – Applications running within the portal • Provides user with a single centralized place to start • Entry point for single sign-on architecture
- 33. Aggregation
- 34. Aggregation
- 35. Personalization • User needs vary within an Enterprise • The more that is understood about a user the greater the ability of the portal to display services and content most relevant to that user. – Groups – Roles – Attributes • Enables user to customize their view of the portal to suit their own preferences. – Ability to add/remove elements from the portal layout – Ability to change how portal elements are organized – Ability to configure details of individual portal elements
- 36. Personalization Student
- 37. Personalization Faculty
- 38. Access Control • Enterprise portals provide a way to control access to individual elements • Individual user access based on: – Group – Role – Attribute • Services not accessible for a user are not displayed in the portal for that user • Access control for accessible elements are managed by the portal
- 41. Delegated Authentication • CAS Proxy Tickets • Shibboleth Delegated SAML Assertions http://www.flickr.com/photos/ 36688133@N00/2894794151/
