  title: Autodesk Upload and Translate a Model for the Viewer
  summary: Create an OSS bucket, upload a design file, translate it to SVF2, and poll the manifest until it is viewable.
  description: >-
    The flagship Autodesk Platform Services pipeline: getting a CAD or BIM file from
    a local disk into the Autodesk Viewer. The workflow creates an Object Storage
    Service bucket, uploads the source design into it, starts a Model Derivative
    translation job, polls the manifest until translation reports success, and reads
    back the viewable GUID the Viewer needs to render the model. Every step spells
    out its request inline so the flow can be read and executed without opening the
    underlying OpenAPI descriptions.

  summary: Take a design file from local disk to a Viewer-ready SVF2 derivative.
  description: >-
    Creates a bucket, uploads the source design, starts an SVF2 translation, waits
    for the manifest to report success, and resolves the viewable GUID. The URN the
    translation job consumes is the URL-safe Base64 encoding of the objectId returned
    by the upload step; that encoding is performed by the client between the upload
    and translation steps and is supplied here as an input.
  inputs:
    type: object
    required:
    - bucketKey
    - objectKey
    - fileContent
    - contentLength
    - urnBase64
    properties:
      bucketKey:
        type: string
        description: >-
          Globally unique bucket key, 3-128 characters of lowercase letters, digits,
          hyphens, underscores.
      policyKey:
        type: string
        description: >-
          Bucket retention policy: transient (24h), temporary (30d), or persistent.
        default: temporary
      objectKey:
        type: string
        description: The object name to store the design under (e.g. "tower.rvt").
      fileContent:
        type: string
        description: The raw bytes of the source design file.
      contentLength:
        type: integer
        description: Size of the source design file in bytes.
      contentType:
        type: string
        description: MIME type of the source design file.
        default: application/octet-stream
      urnBase64:
        type: string
        description: >-
          The URL-safe Base64 encoding of the objectId returned by the upload step.
          Model Derivative addresses source designs by this encoded URN.
      region:
        type: string
        description: Region the derivatives are stored in (us or emea).
        default: us
  steps:
  - stepId: createStorageBucket
    description: >-
      Create the OSS bucket that will hold the source design. Bucket keys are global
      across all of APS, so a 409 here means the key is already taken.
    operationId: createBucket
    requestBody:
      contentType: application/json
      payload:
        bucketKey: $inputs.bucketKey
        policyKey: $inputs.policyKey
    successCriteria:
    - condition: $statusCode == 200
    outputs:
      bucketKey: $response.body#/bucketKey
      bucketOwner: $response.body#/bucketOwner
      policyKey: $response.body#/policyKey
  - stepId: uploadDesign
    description: >-
      Upload the source design file into the bucket. The objectId returned here is
      the URN that Model Derivative translates, once Base64 encoded.
    operationId: uploadObject
    parameters:
    - name: bucketKey
      in: path
      value: $steps.createStorageBucket.outputs.bucketKey

      value: $inputs.objectKey

      value: $inputs.contentLength

      value: $inputs.contentType
    requestBody:
      contentType: application/octet-stream
      payload: $inputs.fileContent
    successCriteria:

    outputs:
      objectId: $response.body#/objectId
      objectKey: $response.body#/objectKey
      size: $response.body#/size
      sha1: $response.body#/sha1
  - stepId: startTranslation
    description: >-
      Start a Model Derivative job that translates the uploaded design into SVF2 with
      both 2D and 3D viewables. Returns 200 when a matching derivative already exists
      and 201 when a new job is accepted.
    operationId: startJob
    parameters:
    - name: x-ads-force
      in: header
      value: false
    - name: x-ads-derivative-format

      value: latest
    requestBody:
      contentType: application/json
      payload:
        input:
          urn: $inputs.urnBase64
        output:
          destination:
            region: $inputs.region
          formats:
          - type: svf2

      result: $response.body#/result
      urn: $response.body#/urn
  - stepId: awaitTranslation
    description: >-
      Poll the manifest until translation reports success. The manifest returns 200
      while the job is still pending or inprogress, so the terminal state is read from
      the body rather than the status code. Ends the workflow if translation fails or
      times out.
    operationId: getManifest
    parameters:
    - name: urn
      in: path
      value: $inputs.urnBase64

    - context: $response.body
      condition: $.status == "success"

  - stepId: resolveViewable
    description: >-
      Read the model views produced by the translation. The GUID of a viewable is what
      the Viewer, the object tree, and the property queries are all addressed by.
    operationId: getMetadata
    parameters:
    - name: urn
      in: path
      value: $inputs.urnBase64
    successCriteria:

    outputs:
      viewableGuid: $response.body#/data/metadata/0/guid
      viewableName: $response.body#/data/metadata/0/name
