  1. JA-SIG ConferenceBal Harbour, Florida08 - 09 December, 2003 Solutions Track Enterprise Calendaring Solutions for Higher Education

  2. Introductions • Greg Barnes • University of Washington • gsbarnes@washington.edu • Laura Appelhans • University of Colorado • laura.appelhans@colorado.edu

  3. Presentation Outline • The Calendaring Problem • Our Solutions • UW Calendar • CU’s WebCal • Conclusion

  4. The problem … from a user's point of view • Too many calendars • personal calendar • academic calendar • department calendar • multiple class calendars • research or workgroup calendar • calendar for every outside interest • other calendars the user don't know about

  5. Types of events • Private:Doctor's appointment at 3:30 • Public: Michael Moore speaks at 3:30 • Group • ad hoc: People in this room meet for drinks at 3:30 • well-known: Department's annual picnic at 3:30 • resources: Need group laptop, slide projector, and conference room #102 for 3:30 presentation

  6. Other problems • Some people already have calendaring solutions they like • Some units already have calendaring solutions they like • Lots of feature requests • Many people are qualified to enter public events • Political concerns/turf wars • Once you build it, how do you get people to use it?

  7. Similarities • Both try to solve personal, public and group calendaring for the entire institution. • Both distribute entering of public events across campus. • Both use open standards. • Both try to interoperate with other calendaring solutions. • Both can be accessed using the web. • Both support calendars accessible to the public. • Both are/will be integrated with their campus portal.

  8. Differences • UW Calendar • Open source • Code is available/modifiable. • Database agnostic (for calendar data and groups) • Authentication agnostic (UW uses PubCookie) • Working toward group calendaring • In production for over two years • CU WebCal • Based on Sun's SunONE calendar • Binary code access only • SleepyCat Berkeley DB for calendar data, SunONE directory for groups/authorization • Kerberos/SunONE directory for authentication • WebCal has group calendaring already • Gradually being phased into production (started August 2002)

  9. UW Calendar

  10. We are building an open source calendaring system for higher education • It will support public, private and group calendars. • It will use existing open standards. • It will support access via the web and other forms of access. • It will integrate with other systems, particularly uPortal.

  11. What we have now • Web applications • personal calendar • public events entry • public events display • Portal view (MyUW, not uPortal) • Beginnings of a CAP server • Small applications • Export to iCalendar/XML/text • Add my class schedule to my calendar • Subscribe to this calendar • Add this event to my calendar

  12. What's next • Better export pages • E-mail notifications • Recurring events • Group events • Struts architecture (pending lawyer approval) • Full CAP server (pending grant approval)

  13. UW Calendar at UW • Java servlets • 2 Apache web servers, 6 Resin application servers, Informix database server • PubCookie for single sign-on (separate server) • In production since 2001 • Portal channel • Database of class meetings updated nightly. Ability to add teaching/student schedule to your personal calendar. • Monitoring, logging, daily reports.

  14. Statistics • 2000-4000 private calendar users, 150-450 logins per day. • 200-500 public calendar logins per day • 300 users authorized to add public events • 126K events. 29K public (24K class meetings), 97K private. • 4100 subscriptions to 60 public calendars, 700 subscribers • 39K public events in private calendars (35K class meetings)

  15. Most desired features at UW • Recurrences, Sync with <X>, Notifications • Small workgroup calendars • New public calendars • To subscribe to • To download/export to another format • Public events entry • Redesign input pages • Extra fields (speaker, opponent, etc.) • Replacement for Corporate Time

  16. Demo …

  17. The open source project • Web site: http://www.washington.edu/ucal • project description • requirements document • CVS • mailing lists • Bugzilla • quickstart release: all you need is Java

  18. CU WebCal

  19. WebCal Project Evolution • Developed requirements document • Vendor research • Selection of iPlanet/SunONE • Formation of calendar team • Pilot within ITS (Information Technology Services) • Campus ‘beta’ group implementation • Process/policy development • Support/training program establishment • Communication plan • Complete faculty/staff launch • Complete campus launch

  20. SunONE Calendar Server • Directory enabled • Web interface • Group scheduling • Synchronization • Email interaction • Invitations • Reminders • Multiple calendars • Individualized permissions • Individual user import/export • Import/export calendars in iCal or XML format

  21. CU WebCal Features • Portal integration • Security • Kerberos authentication • https/ssl/stunnel • Resource scheduling • Check room/classroom availability • Organizational and events calendaring • Support and training program • ITS Service Center • ITS Help Desk • Online self-help • Hands-on training

  22. Calendar Components • Server Specifications • SunOS 5.8 Generic_108528-26 sun4u sparc SUNW, Ultra-4, 480x4, RAID5 • VeriSign certificate • Apache Web Server • ssl/stunnel • Kerberos auth server • Notre Dame Kerberos plugin • SunONE Directory Server • SunONE Calendar Server

  23. HR SIS Calendar Configuration Client ETC calendar.colorado.edu Registry (Oracle) VeriSign Cert Kerberos Server Apache:80 Notre Dame Plugin https:443 MetaMerge 443:stunnel:81 CU Calendar CU Directory Calendar Directory Replication

  24. Demo …

  25. Portal Calendar Components • Server Specifications • Sun SPARC … 8 - Sunfire V100, 500Mhz,1GB • Content switch (load balancing) • uPortal • Directory (inclusive) • Postgres db • ssl/stunnel • Tomcat • Combined with Calendar Server components

  26. Portal Calendar Configuration uPortal (WebCal) Modified inline frame c web proxy uportal.colorado.edu Sends sshtunnel command CU uPortal WebCal CU uPortal Executes calendar script command Executes secondary script Client Result URL w/ valid cred passed SunONE Proxy auth sdk Proxy login completed

  27. Demo …

  28. UW Calendar Open source Cost Java foundation In-house support CU WebCal Sun support Continued development Feature rich Integrated solutions (directory/calendar/ messenger) Advantages

  29. UW Calendar Development intensive No commercial support Lesser functionality Legacy of developers CU WebCal Cost Proprietary code Embedded database Legacy of product Disadvantages
