The MEF Standard consisting of this schema guide and its associated software artifacts (JSON Schemas) defines and describes the product-specific information used in LSO Cantata and LSO Sonata APIs for a set of Business Functions – specifically, Product Offering Qualification, Quote, Order and Inventory, for Subscriber Ethernet Services conforming to MEF 6.3.

Supporting Materials:

The document starts with an overview of LSO Cantata, LSO Sonata and Subscriber Ethernet Services. It then provides a basic information model for the MEF Subscriber Ethernet Service Attributes. The final sections describe the Data Model focused on the JSON Schemas (in YAML format) associated with this specification.

This document can be thought of as a user’s guide for the Subscriber Ethernet Data Model and the schemas provided that embody the Data Model. MEF Services are described by a set of Service Attributes. Each Service Attribute describes an aspect of the service that is agreed between the provider and the user of the service. The document that describes the Service Attributes for Subscriber Ethernet Services is MEF 10.4. The Services, themselves, are specified in MEF 6.3 based on the Service Attributes defined in MEF 10.4.

MEF 10.4 includes 11 EVC Service Attributes, 13 EVC End Point and 17 Subscriber UNI Service Attributes to describe the various components that compose a Subscriber Ethernet Service. This document defines a data model that includes 33 of these Service Attributes and also lists the 8 Service Attributes that are not included in the data model and the reason why each is not included. It also describes how they are organized across the various schemas to support the different types of Subscriber Ethernet Services.
