Re: [calsify] Fwd: New Version Notification for draft-douglass-link-extension-00

Attendees and Organizers are not valid on non-group scheduling events. 
One common invalid event we see when importing events are attempts to 
set those properties.

As event publishers we have a strong need to indicate who is organizing 
the event and who are participants, for example a baseball team or their 
parents.

Even for real group scheduling, the altrep parameter doesn't allow us to 
specify the type, e.g vcard, html etc nor does it allow us to specify 
multiple variants of the same information.

Locations are a typical case and indeed where this all started. altrep 
is allowed but only once. In event publishing especially, it is 
important to have rich location information in a form clients can 
download and display or use to guide people to their destination. Vcard 
seems a good choice for this but clients need to be able to determine 
that the reference is indeed for location information and is in a form 
they can process.

We also have a need to link to other information that is not covered by 
current rfc5545 properties but is vital to event publishers, sponsors 
for example. Event organizers also have a need for a standard way to 
link back to pages that provide access to media, for example video feeds 
or directly to that video feed.
