Table of Contents

1. Introduction

This document defines a data model for Large-Scale Measurement Platforms (LMAP) [RFC7594]. The data model is defined using the YANG [RFC6020] data modeling language. It aims to be consistent with the LMAP Information Model [I-D.ietf-lmap-information-model].

1.1. Terminology

This document uses the LMAP terminology defined in [RFC7594].

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

1.2. Tree Diagrams

A simplified graphical representation of the data model is used in this document. The meaning of the symbols in these diagrams is as follows:

2. Data Model Overview

The tree diagram below shows the structure of the configuration data model.

3. Relationship to the Information Model

The LMAP information model [I-D.ietf-lmap-information-model] is devided into six sections. They are mapped into the YANG data model as explained below:

These six sections are build on the following common information objects:

4. YANG Modules

The modules import definitions from [RFC6991] and [RFC7223] and they reference [RFC7398].
