Track your variables

In the process of building the sample below, there will be a step that adds variables to it to represent the pieces of data that may change from task to task, worker to worker. If you're starting with one of the sample templates, you will need to make sure you're aware of the variables it already uses. When you create your pre-annotation Amazon Lambda script, its output will need to contain values for any of those variables you choose to keep.

The values you use for the variables can come from your manifest file. All the key-value pairs in your data object are provided to your pre-annotation Lambda. If it's a simple pass-through script, matching keys for values in your data object to variable names in your template is the easiest way to pass those values through to the tasks forms your workers see.
