Previous Notes
Plans for Educause presentation
Issues, questions
- Need to know if there's a title already chosen or need to submit
- time allotted?
- audience? Michael Gettes & Oren Sreebny say the audience is less technical but interested in standards in terms of what they can do for them
Content outline
Calendar Standards Historically
- vCalendar: Versit's privately defined format brought to IETF ref
- CalSch? Working Group formed in IETF in 1996
- iCalendar: standardized first in 1998
- Note that first stage standards in IETF don't require interoperability testing
- Interoperability testing required for the next step, which iCalendar has yet to undergo
- iMIP/iTIP also standardized in 1998
- CAP: ongoing effort from 1998 to 2004
- Goal: Calendar access and scheduling protocol
- Many requirements
- Many authors
- CalSch? Working Group shut down in 2004
Calendar standards are dead, long live calendar standards
- Calendar Consortium CalConnect
- Users, vendors, others
- Promote calendar standards
- Support interoperability testing
- Calendaring Roundtable
- Montreal, Sept 22-23
- "Future of interoperable calendaring and scheduling"
- Activity to start Calsify Working Group
- Writing a charter to take iCalendar formats to Draft Standard
- Will need to incorporate results of interop testing
- 95 members on mailing list
- Proposal for Calendar access via WebDAV standard
- 104 members discussing proposal
- So what's changed?
- New Working Group encourages new participation
- New charters can be more focused
- New charters and new proposals take into account today's protocol landscape
- And why do I care?
- Publish schedules for sports events, music events, club get-togethers
- Publish class schedules so students can import them
- Schedule other staff for meetings
- Schedule people from outside the university for meetings
- View somebody else's time commitments if they let you
- Subscribe to be notified when new events are published to favorite calendars
Protocol Landscape?
- Old approach: vertical integration, feature-focused protocols (picture)
- New approach: modular, function-focussed protocols
- WebDAV
- Ubiquitous (and you don't even know it)
- Content-neutral, content access protocol
- picture of WebDAV data model
- picture of WebDAV providing layering for storage of arbitrary formats
- WebDAV Access Control
- A big win -- a standardized content-neutral access control mechanism
- Makes it much faster to design/standardize any new application that needs access control on stored resources
- XMPP and SIP
- Finally some progress towards generic notifications protocols
- You don't want to implement notification as a custom protocol
- You don't want a new application to require an open connection just in order to support notifications
- (is this too technical already?)
- SSL
- LDAP?
