Hello everyone,

I think to do an app where i would save a directed graph.
The vertex and edges there must be dinamics.
The vertex can represent some Tag or Category... or something.
The edge who links the vertex can be N between two vertex and represent
some event or action... and let me explain here what i need to do:

Suppose you have Vertex1 and Vertex2 and are linked by edge1 from vertex1
to vertex2, edge1 have the action "Add if not exist" and mean that if the
user select the vertex1, the system, automatically add vertex2. Even
further, suppose you have a third vertex related to vertex1 by edge2 and
the action of that edge its "delete if exist" so if the user have,
previously, selected vertex3, when select vertex1, vertex3 would be deleted
by edge2.

Make a model to save the graph it's not a problem (save vertex and edges
and specify what action have every edge)... my problem its develop every
type of event or action for the edges, save that event on database and then
execute that event when needed.

Someone have a recommendation for me?
THANK YOU ALL!!!
