=============
+
+Introduction
+-------------
+
+This reference document is the VNF TOSCA Template Requirements for
+OpenO, which provides recommendations and standards for building VNF
+TOSCA templates compatible with OpenO– initial implementations of
+Network Cloud. It has the following features:
+
+1. VNF TOSCA template designer supports GUI and CLI.
+
+2. VNF TOSCA template is aligned to the newest TOSCA protocol, “Working
+ Draft 04-Revision 06”.
+
+3. VNF TOSCA template supports EPA features, such as NUMA, Hyper
+ Threading, SRIOV， etc.
+
+Intended Audience
+-----------------
+
+This document is intended for persons developing VNF TOSCA templates
+that will be orchestrated by OpenO.
+
+Scope
+------
+
+OpenO implementations of Network Cloud supports TOSCA Templates, also
+referred to as TOSCA in this document.
+
+OpenO requires the TOSCA Templates to follow a specific format. This
+document provides the mandatory, recommended, and optional requirements
+associated with this format.
+
+Overview
+---------
+
+The document includes three charters to help the VNF vendors to use the
+VNF model design tools and understand the VNF package structure and VNF
+TOSCA templates.
+
+In the OPENO, VNF Package and VNFD template can be designed by manually
+or via model designer tools. VNF model designer tools can provide the
+GUI and CLI tools for the VNF vendor to develop the VNF Package and VNFD
+template.
+
+The VNF package structure is align to the NFV TOSCA protocol, and
+supports CSAR
+
+The VNFD and VNF package are all align to the NFV TOSCA protocol, which
+supports multiple TOSCA template yaml files, and also supports
+self-defined node or other extensions.
+
+NFV TOSCA Template
+------------------
+
+TOSCA templates supported by OPENO must follow the requirements
+enumerated in this section.
+
+TOSCA Introduction
+------------------
+
+TOSCA defines a Meta model for defining IT services. This Meta model
+defines both the structure of a service as well as how to manage it. A
+Topology Template (also referred to as the topology model of a service)
+defines the structure of a service. Plans define the process models that
+are used to create and terminate a service as well as to manage a
+service during its whole lifetime.
+
+A Topology Template consists of a set of Node Templates and Relationship
+Templates that together define the topology model of a service as a (not
+necessarily connected) directed graph. A node in this graph is
+represented by a *Node Template*. A Node Template specifies the
+occurrence of a Node Type as a component of a service. A *Node Type*
+defines the properties of such a component (via *Node Type Properties*)
+and the operations (via *Interfaces*) available to manipulate the
+component. Node Types are defined separately for reuse purposes and a
+Node Template references a Node Type and adds usage constraints, such as
+how many times the component can occur.

+
+TOSCA Modeling Principles & Data Model
+--------------------------------------
+
+This section describing TOSCA modeling principles and data model for
+NFV, which shall be based on [TOSCA-1.0] and [TOSCA-Simple-Profile-YAML
+V1.0], or new type based on ETSI NFV requirements, etc.
+
+VNF Descriptor Template
+-----------------------
+
+The VNF Descriptor (VNFD) describes the topology of the VNF by means of
+ETSI NFV IFA011 [IFA011] terms such as VDUs, Connection Points, Virtual
+Links, External Connection Points, Scaling Aspects, Instantiation Levels
+and Deployment Flavours.
+
+The VNFD (VNF Descriptor) is read by both the NFVO and the VNFM. It
+represents the contract & interface of a VNF and ensures the
+interoperability across the NFV functional blocks.
+
+The main parts of the VNFD are the following:
+
+- VNF topology: it is modeled in a cloud agnostic way using virtualized
+ containers and their connectivity. Virtual Deployment Units (VDU)
+ describe the capabilities of the virtualized containers, such as
+ virtual CPU, RAM, disks; their connectivity is modeled with VDU
+ Connection Point Descriptors (VduCpd), Virtual Link Descriptors (Vld)
+ and VNF External Connection Point Descriptors (VnfExternalCpd);
+
+- VNF deployment aspects: they are described in one or more deployment
+ flavours, including instantiation levels, supported LCM operations,
+ VNF LCM operation configuration parameters, placement constraints
+ (affinity / antiaffinity), minimum and maximum VDU instance numbers,
+ and scaling aspect for horizontal scaling.
+
+The following table defines the TOSCA Type “derived from” values that
+SHALL be used when using the TOSCA Simple Profile for NFV version 1.0
+specification [TOSCA-Simple-Profile-NFV-v1.0] for NFV VNFD.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The NFV VirtualStorage node type represents a virtual storage entity
+which it describes the deployment and operational behavior of a virtual
+storage resources, as defined by **[ETSI NFV IFA011].**
+
+**[editor note]** open issue: should NFV profile use the current storage
+model as described in YAML 1.1. Pending on Shitao proposal (see
+NFVIFA(17)000110 discussion paper)
+
+**[editor note]** new relationship type as suggested in Matt
+presentation. Slide 8. With specific rules of “valid\_target\_type”
