As discussed informally, in the past, I would like (all or some of) the following relations added to the reference.

continuant begins_to_exist_during process inverse: process has_participant_that_begins_to_exist continuant continuant ceased_to_exist_during process inverse: process has_participant_that_ceases_to_exist continuant

c begins_to_exist_during p <=> continuant(c) and process(p) and first_time_point(p,t1) and last_time_point(p,t2) and not(exists_at(c,t1)) and exists_at(c,t2)

We don't have first_time_point and last_time_point as relations currently. This can be probably be expressed using only part_of and "<" but it looks more complicated so perhaps it is easier to just add first and last_time_point. relations.

etc.

I need (and have been using) such a relation to indicate cases in which a continuant (e.g., rash) begins to exist during an adverse event process.

I also need such a relation for IDO for modeling (among other things) when infections become infectious disorders.
