From 1fc5ce5b48f8c270d5d044356843b8a8566bdccc Mon Sep 17 00:00:00 2001 From: "Threefoot, Jane (jt6620)" Date: Wed, 14 Mar 2018 14:48:10 -0400 Subject: added new aai-schema-ingest library New, lightweight, configurable library for OXM and edge rules json ingest. Allows for broken-up OXM and json for increased model-driven capabilities.
