TOSCA based JSON formatted model following standard: http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html

Most of the TOSCA modeled entity presented in the bellow documentation can be found here: git-link

Tosca Model Reference: 

    Controller Blueprint Archive (.cba)

    The Controller Blueprint Archive is the overall service design, fully model-driven, intent based package needed for SELF SERVICE provisioning and configuration management automation.

    In Dublin release, the CDS community has contributed a framework to automate the resolution of resources for instantiation and any config provisioning operation, such as day0, day1 or day2 configuration.

    The content of the CBA Package is driven from the catalog of reusable data dictionary, component and workflow, delivering a reusable and simplified self service experience.

    The CBA is .zip file, comprised of the following folder structure, the files may vary:

    Flexible Plug-in

    FIX ME: define node type for rest and sql, and the various type of auth

    Interaction with external systems is made plug-able within the CDS design.

    Currently, REST or SQL external systems are supported.

    An external system might be used by multiple resources, or by multiple scripts.

    In order to share the external system information, TOSCA provides a way to create macros using dsl_definitions:

    Artifact Type

    Represents the type of a file, used to target according implementation.

    TOSCA definition: http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454213

    The tosca.artifacts.Implementation was created, derived from tosca.artifacts.Root

      "description": "TOSCA base type for implementation artifacts",
      "version": "1.0.0",
      "derived_from": "tosca.artifacts.Root"
    }


    Bellow is a list of supported artifact types

      artifact-mapping-resource

      This type is meant to represent mapping files. Defines the contract of each resource to be resolved. Each placeholder in a template must have a corresponding mapping definition, see CDS Modeling Concepts. File must have .json extension.

        ],
        "derived_from": "tosca.artifacts.Implementation"
      }

      artifact-template-velocity

      Represents an Apache Velocity template. Apache Velocity allows you to insert logic (if / else / loops / etc) when processing the output of a template/text. File must have .vtl extension.

      A template can represent anything, such as device config, payload to interact with 3rd party systems, resource-accumulator template, etc...

          Data type

          Represents the schema of a specific type of data.

          Supports both primitive and complex data types, complex being a list or a structure.

          TOSCA definition: http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454187


          Bellow is a list of supported data types

            datatype-resource-assignment

            Used to define CDS Modeling Concepts

            That datatype represent an resource to be resolved.

            Property Description
            input-param Whether the resource can be provided as input.
            dictionary-name Reference to the name of the data dictionary (see Data Dictionary).
            dictionary-source Reference the source to use to resolve the resource (see Resource source).
            dependencies List of dependencies required to resolve this resource.
            updated-date Date when mapping was upload.

            Workflow

            A workflow defines an overall action to be taken on the service; it can be composed of one or multiple sub-actions to execute.

            A CBA can have as many workflows as needed.

            TOSCA definition: http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454203

            Single action

            The workflow is directly backed by a CDS Modeling Concepts of type CDS Modeling Concepts

            Multiple sub-actions

            The workflow is backed by Directed Graph engine, CDS Modeling Concepts of type dg-generic, and are imperative workflows.

            A DG used as workflow for CDS is composed of multiple execute nodes; each individual execute node refers to a plugin, that is a CDS Modeling Concepts of type CDS Modeling Concepts.

            Template

            A template is an artifact, and uses CDS Modeling Concepts and artifact-template-velocity.

            A template is parameterized and each parameter must be defined in a corresponding mapping file.

            In order to know which mapping correlates to which template, the file name must start with an artifact-prefix, serving as identifier to the overall template + mapping.

            The requirement is as follows:

            ${artifact-prefix}-template
            ${artifact-prefix}-mapping

            Resource accumulator

            In order to resolve HEAT environment variables, resource accumulator templates are being in used in Dublin.

            These templates are specific to the pre-instantiation scenario, and relies on GR-API within SDNC.

            It is composed of the following sections:

            • resource-accumulator-resolved-data: defines all the resources that can be resolved directly from the context. It expresses a direct mapping between the name of the resource and its value.

            • capability-data: defines what capability to use to create a specific resource, along with the ingredients required to invoke the capability and the output mapping.

            Scripts

            Library

            NetconfClient

            In order to facilitate NETCONF interaction within scripts, a python NetconfClient binded to our Kotlin implementation is made available. This NetconfClient can be used when using the component-netconf-executor.

            The client can be find here: https://github.com/onap/ccsdk-apps/blob/master/components/scripts/python/ccsdk_netconf/netconfclient.py

            ResolutionHelper

            When executing a component executor script, designer might want to perform resource resolution along with template meshing directly from the script itself.

            The helper can be find here: https://github.com/onap/ccsdk-apps/blob/master/components/scripts/python/ccsdk_netconf/common.py

            Resource Definition aka Data dictionary

            A data dictionary models the how a specific resource can be resolved.

            A resource is a variable/parameter in the context of the service. It can be anything, but it should not be confused with SDC or Openstack resources.

            A data dictionary can have multiple sources to handle resolution in different ways.

            The main goal of data dictionary is to define re-usable entity that could be shared.

            Creation of data dictionaries is a standalone activity, separated from the blueprint desig

            As part of modelling a data dictionary entry, the following generic information should be provided:

            Property Description Scope
            name Data dictionary name Mandatory
            tags Information related Mandatory
            updated-by The creator Mandatory
            property Defines type and description, as nested JSON Mandatory
            sources List of resource source Mandatory

            Bellow are properties that all the resource source have will have

            The modeling does allow for data translation between external capability and CDS for both input and output key mapping.

            Property Description Scope
            input-key-mapping map of resources required to perform the request/query. The left hand-side is what is used within the query/request, the right hand side refer to a data dictionary instance. Optional
            output-key-mapping name of the resource to be resolved mapped to the value resolved by the request/query. Optional
            key-dependencies

            list of data dictionary instances to be resolved prior the resolution of this specific resource.

            during run time execution the key dependencies are recursively sorted and resolved in batch processing using the acyclic graph algorithm.

            Optional

            Example:
            vf-module-model-customization-uuid and vf-module-label are two data dictionaries. A SQL table, VF_MODULE_MODEL, exist to correlate them.

            Here is how input-key-mapping, output-key-mapping and key-dependencies can be used:

            vf-module-label data dictionary
            {
              "name" : "vf-module-label",
              "tags" : "vf-module-label",
              "updated-by" : "adetalhouet",
              "property" : {
                "description" : "vf-module-label",
                "type" : "string"
              },
              "sources" : {
                "primary-db" : {
                  "type" : "source-primary-db",
                  "properties" : {
                    "type" : "SQL",
                    "query" : "select sdnctl.VF_MODULE_MODEL.vf_module_label as vf_module_label from sdnctl.VF_MODULE_MODEL where sdnctl.VF_MODULE_MODEL.customization_uuid=:customizationid",
                    "input-key-mapping" : {
                      "customizationid" : "vf-module-model-customization-uuid"
                    },
                    "output-key-mapping" : {
                      "vf-module-label" : "vf_module_label"
                    },
                    "key-dependencies" : [ "vf-module-model-customization-uuid" ]
                  }
                }
              }
            }

            Regardless the source used within a Data Dictionary, the resource value can be overridden through input.

            Resource source

            Defines the contract to resolve a resource.

            A resource source is modeled, following TOSCA node_type definition, and derives from the tosca.nodes.Root

            Uses CDS Modeling Concepts

            ONAP defines common resource source definitions, derived by the tosca.nodes.ResourceSource

              Input

              Expects the value to be provided as input to the request.

              git link

              source-input
              {

                "derived_from": "tosca.nodes.ResourceSource"
              }

              Default

              Expects the value to be defaulted in the model itself.

              git link

              source-default
              {

                "derived_from": "tosca.nodes.ResourceSource"
              }

              REST

              Expects the URI along with the VERB and the payload, if needed.

              CDS is currently deployed along the side of SDNC, hence the default rest connection provided by the framework is to SDNC MDSAL.

              Connection to a specific REST system can be expressed through the endpoint-selector property, which refers to a macro defining the information about the REST system the connect to. Understand TOSCA Macro in the context of CDS.

              Few ways are available to authenticate to the REST system:

              • token-auth
                "dsl_definitions": {
                  "dynamic-rest-source": {
                	"type" : "token-auth",
                	"url" : "http://localhost:32778",
                	"token" : "Token 0123456789abcdef0123456789abcdef01234567"
                  }
                }
              • basic-auth
                "dsl_definitions": {
                  "dynamic-rest-source": {
                	"type" : "basic-auth",
                	"url" : "http://localhost:32778",
                	"username" : "bob",
                	"password": "marley"
                 }
                }
              • TBD - The trustore and the keystore can be provide as environment through the Environment folder in the CBA.

                ssl-basic-auth
                "dsl_definitions": {
                  "dynamic-rest-source": {
                	"type" : "ssl-basic-auth",
                	"url" : "http://localhost:32778",
                	"keyStoreInstance": "JKS or PKCS12",
                	"sslTrust": "trusture",
                	"sslTrustPassword": "trustore password",
                	"sslKey": "keystore",
                	"sslKeyPassword: "keystore password"
                 }
                }

              SQL

              Expects the SQL query to be modeled; that SQL query can be parameterized, and the parameters be other resources resolved through other means. If that's the case, this data dictionary definition will have to define key-dependencies along with input-key-mapping.

              CDS is currently deployed along the side of SDNC, hence the primary database connection provided by the framework is to SDNC database.
