Finding Extractpackagename from EDM Job Result REST API

Summary:

We are submitting an EDM Extract package and then querying the Job result for the submitted Job run id and the response of the Job result doesnt contain the extractPackageName that is submitted. We do get the extractPackagename in the description. Is the string coming there in description the only way to find the extractPackagename and if that is the case can the string be consistent and wont change in future ?
