Finally, HAS provides an traceable mechanism for what-if analysis which is critical for ease of
understanding a homing recommendation and resolving infeasibility scenarios.
+OF-HAS is the implementation of the ONAP Homing Service. The formal project name in ONAP is *OF-HAS*.
+The informal name for the project is *Conductor* (inherited from the seed-code), which is interchangeably
+used through the project.
+
+Given the description of what needs to be deployed (demands) and the placement requirements (constraints),
+Conductor determines placement candidates that meet all constraints while optimizing the resource usage
+of the AIC infrastructure. A customer request may be satisfied by deploying new VMs in AIC (AIC inventory)
+or by using existing service instances with enough remaining capacity (service inventory).
+
+From a canonical standpoint, Conductor is known as a *homing service*, in the same way OpenStack Heat
+is an orchestration service, or Nova is a compute service.

Request Parameters
~~~~~~~~~~~~~~~~~~
-+--------------------+------------+----------+------------------------+
-| Parameter | Style | Type | Description |
-+====================+============+==========+========================+
-| ``name`` | plain | xsd:stri | A name for the new |
-| (Optional) | | ng | plan. If a name is not |
-| | | | provided, it will be |
-| | | | auto-generated based |
-| | | | on the homing |
-| | | | template. This name |
-| | | | must be unique within |
-| | | | a given Conductor |
-| | | | environment. When |
-| | | | deleting a plan, its |
-| | | | name will not become |
-| | | | available for reuse |
-| | | | until the deletion |
-| | | | completes |
-| | | | successfully. Must |

-| | | | parameter is |
-| | | | immutable. |
-+--------------------+------------+----------+------------------------+
-| ``id`` (Optional) | plain | csapi:UU | The UUID of the plan. |
-| | | ID | UUID is assigned by |
-| | | | Conductor if no id is |

-| | | | request. |
-+--------------------+------------+----------+------------------------+
-| ``transaction_id`` | plain | csapi:UU | The transaction id |

-| | | | logs should have this |
-| | | | transaction id for |
-| | | | tracking purposes. |

-| (Optional) | | | of files referenced. |

+| Parameter | Style | Type | Description |
++====================+=======+============+===================+
+| ``name`` | plain | xsd:string | A name for the |
+| (Optional) | | | new plan. If a |
+| | | | name is not |
+| | | | provided, it |
+| | | | will be |
+| | | | auto-generated |
+| | | | based on the |
+| | | | homing |
+| | | | template. This |
+| | | | name must be |
+| | | | unique within |
+| | | | a given |
+| | | | Conductor |
+| | | | environment. |
+| | | | When deleting |
+| | | | a plan, its |
+| | | | name will not |
+| | | | become |
+| | | | available for |
+| | | | reuse until |

+| | | | Section 2.3). |
+| | | | This parameter |
+| | | | is immutable. |
++--------------------+-------+------------+-------------------+
+| ``id`` | plain | csapi:UUID | The UUID of |
+| (Optional) | | | the plan. UUID |
+| | | | is assigned by |
+| | | | Conductor if |
+| | | | no id is |
+| | | | provided in |
+| | | | the request. |
++--------------------+-------+------------+-------------------+
+| ``transaction_id`` | plain | csapi:UUID | The |
+| | | | transaction id |
+| | | | assigned by |
+| | | | MSO. The logs |
+| | | | should have |
+| | | | this |
+| | | | transaction id |
+| | | | for tracking |
+| | | | purposes. |
++--------------------+-------+------------+-------------------+
+| ``files`` | plain | xsd:dict | Supplies the |
+| (Optional) | | | contents of |
+| | | | files |
+| | | | referenced in |
+| | | | the template. |
+| | | | Conductor |
+| | | | templates can |
+| | | | explicitly |
+| | | | reference |
+| | | | files by using |
+| | | | the |
+| | | | ``get_file`` |
+| | | | intrinsic |
+| | | | function. The |
+| | | | value is a |
+| | | | JSON object, |
+| | | | where each key |
+| | | | is a relative |
+| | | | or absolute |
+| | | | URI which |
+| | | | serves as the |
+| | | | name of a |
+| | | | file, and the |
+| | | | associated |
+| | | | value provides |
+| | | | the contents |
+| | | | of the file. |
+| | | | Additionally, |
+| | | | some template |
+| | | | authors encode |
+| | | | their user |
+| | | | data in a |
+| | | | local file. |
+| | | | The Homing |
+| | | | client (e.g., |
+| | | | a CLI) can |
+| | | | examine the |
+| | | | template for |
+| | | | the |
+| | | | ``get_file`` |
+| | | | intrinsic |
+| | | | function |
+| | | | (e.g., |
+| | | | ``{get_file: f |
+| | | | ile.yaml}``) |
+| | | | and add an |
+| | | | entry to the |
+| | | | ``files`` map |
+| | | | with the path |
+| | | | to the file as |
+| | | | the name and |
+| | | | the file |
+| | | | contents as |
+| | | | the value. Do |
+| | | | not use this |
+| | | | parameter to |
+| | | | provide the |
+| | | | content of the |
+| | | | template |
+| | | | located at the |
+| | | | ``template_url`` |
+| | | | address. |
+| | | | Instead, use |
+| | | | the |
+| | | | ``template`` |
+| | | | parameter to |
+| | | | supply the |
+| | | | template |
+| | | | content as |
+| | | | part of the |
+| | | | request. |
++--------------------+-------+------------+-------------------+
+| ``template_url`` | plain | xsd:string | A URI to |
+| (Optional) | | | the location |
+| | | | containing the |
+| | | | template on |
+| | | | which to |
+| | | | perform the |
+| | | | operation. See |
+| | | | the |
+| | | | description of |
+| | | | the |
+| | | | ``template`` |
+| | | | parameter for |
+| | | | information |
+| | | | about the |
+| | | | expected |
+| | | | template |
+| | | | content |
+| | | | located at the |
+| | | | URI. This |
+| | | | parameter is |
+| | | | only required |
+| | | | when you omit |
+| | | | the |
+| | | | ``template`` |
+| | | | parameter. If |
+| | | | you specify |
+| | | | both |
+| | | | parameters, |
+| | | | this parameter |
+| | | | is ignored. |
++--------------------+-------+------------+-------------------+
+| ``template`` | plain | xsd:string | The template |
+| | | or xsd:dict| on which to |
+| | | | perform the |
+| | | | operation. See |
+| | | | the Homing |
+| | | | Template |
+| | | | Guide |
+| | | | for complete |
+| | | | information on |
+| | | | the format. |
+| | | | This parameter |
+| | | | is either |
+| | | | provided as a |
+| | | | ``string`` or |
+| | | | ``dict`` in |
+| | | | the JSON |
+| | | | request body. |
+| | | | For ``string`` |
+| | | | content it may |
+| | | | be a JSON- or |
+| | | | YAML-formatted |
+| | | | Conductor |
+| | | | template. For |
+| | | | ``dict`` |
+| | | | content it |
+| | | | must be a |
+| | | | direct JSON |
+| | | | representation |
+| | | | of the |
+| | | | Conductor |
+| | | | template. This |
+| | | | parameter is |
+| | | | required only |
+| | | | when you omit |
+| | | | the |
+| | | | ``template_url`` |
+| | | | parameter. If |
+| | | | you specify |
+| | | | both |
+| | | | parameters, |
+| | | | this value |
+| | | | overrides the |
+| | | | ``template_url`` |
+| | | | parameter |
+| | | | value. |
++--------------------+-------+------------+-------------------+
+| ``timeout`` | plain | xsd:number | The timeout |
+| (Optional) | | | for plan |
+| | | | creation in |
+| | | | minutes. |
+| | | | Default is 1. |
++--------------------+-------+------------+-------------------+
+| ``limit`` | plain | xsd:number | The maximum |
+| (Optional) | | | number of |
+| | | | recommendations |
+| | | | to return. |
+| | | | Default is 1. |
++--------------------+-------+------------+-------------------+
+
+**NOTE**: ``files``, ``template_url``, and ``timeout`` are not yet
+supported.

+| | | | if available. |
++--------------------+----------+------------+--------------------+
+| ``links`` | plain | xsd:list | A list of URLs |
