Image Artist: Communication pathway for Harmony 5.2 data transfer

This article outlines the communication pathways when transferring image data from Harmony 5.2 (or below) to Image Artist. 

Transfer Workflow

The image transfer from Harmony to Image Artist follows a four-step process:

1. Connection Establishment

Harmony initiates a connection to the Image Artist system.

2. Metadata Push

Harmony sends an XML file to Image Artist. This XML contains a list of URLs, each pointing to the network location of an image stored on the Harmony PC.

3. Image Retrieval 

Image Artist uses the URLs provided in the XML to perform HTTP GET requests and download the images directly from Harmony.

4. Status Polling

While the transfer is ongoing, Harmony periodically polls Image Artist to check the status of the job.

Communication Flow

The communication between Harmony and Image Artist is bi-directional:

• Harmony → Image Artist:
  • Step 1: Connection initiation
  • Step 2: XML metadata push  
  • Step 4: Status polling
• Image Artist → Harmony:  
  • Step 3: Image download via HTTP GET

Firewall and Port Requirements

To ensure successful communication and data transfer, the following TCP ports must be open:

• Image Artist Host: TCP 80 (HTTP) Inbound
• Harmony Host: TCP 80 (HTTP) Inbound
