anca,

perhaps it would be possible that common part handles removing and
expiration of publications as well as refreshing of event state when it
does not need to be modified.

it would be responsibility of each event package to check the content
type and body of those publish requests that either create initial
publication or modify event state of existing publication.

regarding receiving subscribe requests and sending notify requests,
perhaps it would be possible that common part takes care of them.
