2.2. 2000-2004
Work on CAP — stopped
Interoperability testing — stopped
Work on iCalendar, iTIP and iMIP — stopped
IETF CALSCH working group — stopped
The draft RFCs were not ready
Too ambiguous
Too complex
Untested
Calendaring and Scheduling Vendors continued to use the RFCs as they could
Where the RFCs were inadequate vendors were forced to develop workarounds or unique extensions
Work on follow-on or related specifications was hampered by being “built on sand”
Vendors — and users — became more and more frustrated by the lack of movement in calendaring standards and interoperability
Interoperability between calendaring systems was mostly still a dream
Somewhere around 2004 things started to move again
Some vendors began moving towards alternatives to the base RFCs
Interoperability seemed less important than progressing products
Work was begun on CalDAV as a prospective standard for a calendar access protocol, recognizing that CAP was a dead end
