DRAFT Data Process Service

Overview

The Data Process Service is a web service hosted by Fusion Registry which accepts a dataset (multiple formats supported) and a process instruction, which tells the Fusion Registry how to process the data, for example validate, map, transform, export.

Workflow

The Data Process Service has the following workflow

1. Load Data - Data is submitted using HTTP Post. The server provides a token to be able to perform further actions on the data
2. Run Process - The process to execute is sent to the server, along with the token of which dataset to apply the process to. The server provides a token to track the process
3. Track Progress - A GET request to track the progress of a running process, using the processes' unique token as supplied by the server
4. Export Data - If the final stage of a Process is to store the data in a temporary store, then it can be exported in any data format supported by Fusion Registry

Any data loaded is stored for 2 minutes, if there is no activity on the data 2 minutes after it is loaded, it will be evicted from the system.
