#82 new subbranch for events

[Nicolas Le Novère]

When we refactor the occurring entity branch, it was partially to discriminate between process and events. We can now start to add those events. The subbranch must be a child of "SBO:0000231 - occurring entity representation" and a sibbling of "SBO:0000375 - process". As first terms, I propose:

instantaneous modification of a participant quantity
==== instantaneous increase of a participant quantity
======== creation of a participant
==== instantaneous decrease of a participant quantity

We will have some more soon. But we can start to add them as we annotate BioModels entries.

should we create event as sibling to process?

event: An occurrence or action that takes places at a discrete point in time.

after some modification of the proposal:

event
=== event duration
=== event outcome
====== participant quantity modification
========= participant quantity increase
============ participant creation
============ participant introduction
========= participant quantity decrease
============ participant destruction
============ participant removal

How's that?

[Nicolas Le Novère]

Yes, for the sibbling of process.

No for the tree. Event duration would be a parameter. Event outcome is the event.
