From d10a218c76633374f083f7a2802c198e93a6abae Mon Sep 17 00:00:00 2001 From: michaere Date: Wed, 27 Jun 2018 09:51:34 +0100 Subject: Apply multiplicity Rule upon Edge creation Uses multiplicity type from dbedge rules json to validate whether to and from vertices meet the multiplicity constraint e.g. ONE2MANY. This validation is applied when creating or updating an edge.
