+Artifact Type
+-------------------------------------
+
+Represents the **type of a artifact**, used to **identify** the
+**implementation** of the functionality supporting this type of artifact.
+
+`TOSCA definition <http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html#_Toc494454213>`_
+
+This node was created, derived from ``tosca.artifacts.Root`` to be the root TOSCA node for all artifact.

+.. tabs::
+
+ .. tab:: Velocity
+
+ **artifact-template-velocity**
+
+ Represents an Apache Velocity template.
+
+ Apache Velocity allow to insert **logic** (if / else / loops / etc) when processing the output of a template/text.
+
+ File must have **.vtl** extension.
+
+ The **template** can represent anything, such as device config, payload to interact with 3rd party systems,
+ :ref:`resource-accumulator template`, etc...
+
+ Often a template will be **parameterized**, and each **parameter**
+ must be defined within an mapping file (see 'Mapping' in this tab).

+
+ Jinja template allow to insert **logic** (if / else / loops / etc) when processing the output of a template/text.
+
+ File must have **.jinja** extension.
+
+ The **template** can represent **anything**, such as device config,

+ "jinja"
+ ],
+ "derived_from": "tosca.artifacts.Implementation"
+ }
+
+ .. tab:: Mapping
+
+ **artifact-mapping-resource**
+
+ This type is meant to represent **mapping** files defining the **contract of each resource** to be resolved.
+
+ Each **parameter** in a template **must** have a corresponding mapping definition,
+ modeled using datatype-resource-assignment (see :ref:`data_type`-> resources-asignment).
+
+ Hence the mapping file is meant to be a list of entries defined using datatype-resource-assignment
+ (see :ref:`data_type`-> resources-asignment).
+
+ File must have **.json** extension.
+
+ The **template** can represent **anything**, such as device config,
+ payload to interact with 3rd party systems, resource-accumulator template, etc...
+
+ `Here <https://github.com/onap/ccsdk-cds/blob/master/components/model-catalog/definition-type/starter-type/artifact_type/artifact-mapping-resource.json>`_

+ :caption: **artifact-mapping-resource**
+
+ {
+ "description": "Resource Mapping File used along with Configuration template",
+ "version": "1.0.0",
+ "file_ext": [
+ "json"
+ ],
+ "derived_from": "tosca.artifacts.Implementation"
+ }
+
+ The mapping file basically contains a reference to the data dictionary to use
+ to resolve a particular resource.
+
+ The data dictionary defines the HOW and the mapping defines the WHAT.
+
+ **Relation between data dictionary, mapping and template.**
+
+ Below are two examples using color coding to help understand the relationships.
+
+ In orange is the information regarding the template. As mentioned before,
+ template is part of the blueprint itself, and for the blueprint to know what template to use,
+ the name has to match.
+
+ In green is the relationship between the value resolved within the template,
+ and how it's mapped coming from the blueprint.
+
+ In blue is the relationship between a resource mapping to a data dictionary.
+
+ In red is the relationship between the resource name to be resolved and the HEAT environment variables.
+
+ The key takeaway here is that whatever the value is for each color, it has to match all across.
+ This means both right and left hand side are equivalent; it's all on the designer to express
+ the modeling for the service. That said, best practice is example 1.

+
+ .. tab:: Directed Graph
+
+ **artifact-directed-graph**
+
+ Represents a directed graph.
+
+ This is to represent a **workflow**.
+
+ File must have **.xml** extension.
+
+ Here is the list of executors currently supported (see here for explanation and full potential list:

+
+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 design.
+
+As part of modelling a data dictionary entry, the following generic information should be provided:
+
+.. list-table::
+ :widths: 25 50 25
+ :header-rows: 1
+
+ * - Property
+ - Description
+ - Scope
+ * - updated-by
+ - The creator
+ - Mandatory
+ * - tags
+ - Information related
+ - Mandatory
+ * - sources
+ - List of resource source instance (see :ref:`resource source`)
+ - Mandatory
+ * - property
+ - Defines type and description, as nested JSON
+ - Mandatory
+ * - name
+ - Data dictionary name
+ - Mandatory
+
+**Bellow are properties that all the resource source can have**
+
+The modeling does allow for **data translation** between external capability
+and CDS for both input and output key mapping.
+
+.. list-table::
+ :widths: 25 50 25
+ :header-rows: 1
+
+ * - 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
+ <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`_
+ - 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.
+

+Dynamic Payload
+-------------------------------------
+
+One of the most important API provided by the run time is to execute a CBA Package.
+
+The nature of this API **request** and **response** is **model
+driven** and **dynamic**.
+
+Here is how the a **generic request** and **response** look like.
+
+.. list-table::
+ :widths: 50 50
+ :header-rows: 1
+
+ * - request
+ - response
+ * - .. code-block:: json

+ "$actionName-response": {
+ }
+ }
+ }
+
+The ``actionName``, under the ``actionIdentifiers`` refers to the name of a
+Workflow (see :ref:`workflow`)
+
+The content of the ``payload`` is what is fully dynamic / model driven.
+
+The first **top level element** will always be either
+``$actionName-request`` for a request or ``$actionName-response`` for a response.
+
+Then the **content within this element** is fully based on the
+**workflow** **inputs** and **outputs**.
+
+During the :ref:`enrichment` CDS will aggregate all the resources
+defined to be resolved as input (see :ref:`node_type` -> Source -> Input), within mapping definition files
+(see :ref:`artifact_type` -> Mapping), as data-type, that will then be use as type
+of an input called ``$actionName-properties``. \ No newline at end of file

+
+Enrichment
+-----------
+
+The idea is that the CBA is a self-sufficient package, hence requires
+all the various types definition its using.
+
+Reason for this is the types its using might evolve. In order for the
+CBA to be bounded to the version it has been using when it has been
+designed, these types are embedded in the CBA, so if they change, the
+CBA is not affected.
+
+The enrichment process will complete the package by providing all the
+definition of types used:
+
+* gather all the node-type used and put them into a :file:`node_types.json` file
+* gather all the data-type used and put them into a :file:`data_types.json` file
+* gather all the artifact-type used and put them into a :file:`artifact_types.json` file
+* gather all the data dictionary definitions used from within the mapping files and put them
+ into a :file:`resources_definition_types.json` file
+
+.. warning::
+ Before uploading a CBA, it must be enriched. If your package is already enrich,
+ you do not need to perform enrichment again.
+
+The enrichment can be run using REST API, and required the **.zip** file as input.

+
+In CDS, we have mainly two distinct types: components and source. We have some other type as well,
+listed in the other section.
+
+.. tabs::
+
+ .. tab:: Component
+
+ **Component:**
+
+ Used to represent a **functionality** along with its **contract**, such as **inputs**, **ouputs**, and **attributes**
+
+ `Here <https://github.com/onap/ccsdk-cds/blob/master/components/model-catalog/definition-type/starter-type/node_type/tosca.nodes.Component.json>`_
+ is the root component TOSCA node type from which other node type will derive:
+
+ .. code-block:: json
+ :caption: **tosca.nodes.Component**
+
+ {
+ "description": "This is default Component Node",
+ "version": "1.0.0",
+ "derived_from": "tosca.nodes.Root"
+ }
+
+ **Bellow is a list of supported components**
+
+ .. tabs::
+
+ .. tab:: resource-resolution
+
+ **component-resource-resolution:**
+
+ Used to perform resolution of **resources**.
+
+ Requires as many as artifact-mapping-resource (see :ref:`artifact_type` -> Mapping) AND
+ artifact-template-velocity (see :ref:`artifact_type` -> Jinja) as needed.
+
+ **Output result:**
+
+ Will put the resolution result as an **attribute** in the workflow context called **assignment-params**.
+
+ Using the :ref:`undefined <get_attribute expression>`, this attribute can be retrieve to be
+ provided as workflow output (see :ref:`workflow`).
+
+ **Specify which template to resolve:**
+
+ Currently, resolution is bounded to a template. To specify which template to use, you
+ need to fill in the `artifact-prefix-names` field.
+
+ See :ref:`template` to understand what the artifact prefix name is.
+
+ **Storing the result:**
+
+ To store each resource being resolved, along with their status, and the resolved template, `store-result` should be set to `true`.
+
+ Also, when storing the data, it must be in the context of either a `resource-id` and `resource-type`, or based on a given `resolution-key`
+
+
+ The concept of resource-id / resource-type, or resolution-key, is to uniquely identify a specific resolution that
+ has been performed for a given action. Hence the resolution-key has to be unique for a given blueprint name, blueprint version, action name.
+
+ Through the combination of the fields mentioned previously, one could retrieved what has been resolved. This is useful to manage the life-cycle of the resolved resource, the life-cycle of the template, along with sharing with external systems the outcome of a given resolution.
+
+ The resource-id / resource-type combo is more geared to uniquely identify a resource in AAI, or external system. For example, for a given AAI resource, say a PNF, you can trigger a given CDS action, and then you will be able to manage all the resolved resources bound to this PNF. Even we could have a history of what has been assigned, unassigned for this given AAI resource.
+
+ .. warning:: Important not to confuse and AAI resource (e.g. a topology element,
+ or service related element) with the resources resolved by CDS, which can be seen
+ as parameters required to derived a network configuration.
+
+ **Run the resolution multiple time:**
+
+ If you need to run the same resolution component multiple times, use the field `occurence`.
+ This will add the notion of occurrence to the resolution, and if storing the results, resources
+ and templates, they will be accessible for each occurrence.
+
+ Occurrence is a number between 1 and N; when retrieving information
+ for a given occurrence, the first iteration starts at 1.
+
+ This feature is useful when you need to apply the same configuration accross network elements.

+Modeling Concepts
+==================
+
+CDS is a framework to automate the **resolution of resources** for
+**instantiation** and any **config** provisioning operation, such as
+day0, day1 or day2 configuration.
+
+CDS has a both **design time** and **run time** activities; during
+design time, **Designer** can **define** what **actions** are required
+for a given service, along with anything comprising the action. The
+design produce a :ref:`CBA Package<cba>`. Its **content** is driven from a
+**catalog** of **reusable data dictionary** and **component**,
+delivering a reusable and simplified **self service** experience.
+
+DS modelling is mainly based on `TOSCA
+standard, <http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/csd01/TOSCA-Simple-Profile-YAML-v1.2-csd01.html>`_
+using JSON as reprensentation.
+
+Most of the TOSCA modeled entity presented in the bellow documentation
+can be found
+`here <https://github.com/onap/ccsdk-cds/tree/master/components/model-catalog/definition-type/starter-type>`_.

+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-cds/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.

+Southbound Interfaces
+-------------------------
+
+CDS comes with native python 3.6 support and Ansible AWX (Ansible Tower):
+idea is Network Ops are familiar with Python and/or Ansible, and our goal is not to dictate the SBI to use for
+their operations. Ansible and Python provide already many, and well adopted,
+SBI libraries, hence they could be utilized as needed.
+
+CDS also provide native support for the following libraries:
+
+* NetConf
+* REST
+* CLI
+* SSH
+* gRPC (hence gNMI / gNOI should be supported)
+
+CDS also has extensible REST support, meaning any RESTful interface used for network interaction can be used,
+such as external VNFM or EMS. \ No newline at end of file

+Template
+-----------
+
+A template is an **artifact**, and uses artifact-mapping-resource (see :ref:`artifact_type` -> Mapping)
+and artifact-template-velocity (see :ref:`artifact_type` -> 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.

+
+Tests
+--------
+
+The **tests** folder contains the **uat.yaml** file for execution the cba actions for sunny day and rainy day
+scenario using mock data. The process to generate the uat file is documented TBD. The file can be dragged
+and drop to the Tests folder after the test for all actions are executed.
+
+NOTE: You need to activate the "uat" Spring Boot profile in order to enable the spy/verify endpoints.
+They are disabled by default because the mocks created at runtime can potentially cause collateral problems in production.
+You can either pass an option to JVM (``-Dspring.profiles.active=uat``) or set and export an
+environment variable (``export spring_profiles_active=uat``).
+
+A quick outline of the UAT generation process follows:
+
+1. Create a minimum :file:`uat.yaml` containing only the NB requests to be sent to the BlueprintsProcessor (BPP) service;
+2. Submit the blueprint CBA and this draft :file:`uat.yaml` to BPP in a single HTTP POST call:
+
+ ``curl -u ccsdkapps:ccsdkapps -F cba=@<path to your CBA file> -F uat=@<path to the
+ draft uat.yaml> http://localhost:8080/api/v1/uat/spy``
+3. If your environment is properly setup, at the end this service will generate the complete :file:`uat.yaml`;
+4. Revise the generate file, eventually removing superfluous message fields;
+5. Include this file in your CBA under :file:`Tests/uat.yaml`;
+6. Submit the candidate CBA + UAT to be validated by BPP, that now will create runtime mocks to simulate
+ all SB collaborators, by running:
+
+ ``$ curl -u ccsdkapps:ccsdkapps -F cba=@<path to your CBA file> http://localhost:8080/api/v1/uat/verify``
+7. Once validated, your CBA enhanced with its corresponding UAT is eligible
+ to be integrated into the CDS project, under the folder :file:`components/model-catalog/blueprint-model/uat-blueprints`.
+
+Reference link for sample generated uat.yaml file for pnf plug & play use case:
+`uat.yaml file <https://gerrit.onap.org/r/gitweb?p=ccsdk/cds.git;a=tree;f=components/model-catalog/blueprint-model/uat-blueprints/pnf_config/Tests;h=230d506720c4a1066784c1fe9e0ba0206bbb13cf;hb=refs/heads/master>`_.
+
+As UAT is part of unit testing, it runs in jenkins job
+`ccsdk-cds-master-verify-java <https://jenkins.onap.org/job/ccsdk-cds-master-verify-java/>`_

+The workflow is directly backed by a component (see :ref:`node_type` -> Component).
+
+In the example bellow, the target of the workflow's steps resource-assignment is ``resource-assignment``
+which actually is the name of the ``node_template`` defined after, of type ``component-resource-resolution``.

+Multiple sub-actions
+**********************
+
+The workflow is backed by a Directed Graph engine, dg-generic (see :ref:`node_type` -> DG,
+and is an **imperative** workflow.
+
+A DG used as workflow for CDS is composed of multiple execute nodes; each individual
+execute node refers to an modelled Component (see :ref:`node_type` -> Component) instance.
+
+In the example above, you can see the target of the workflow's steps execute-script is
+``execute-remote-ansible-process``, which is a node_template of type ``dg_generic``
