Design : SAK-2963

Releases

Components

  • SmartSite Gradebook2 Institutional Adviser (GB2IA)

  • Final Grade Submission Enterprise Service (FGSES)

  • AFS

  • Final Grading Tool (FGT)

Process

  1. GB2IA makes a POST request to the FGSES

    1. The request's content contains the grading information encoded in IMS ES V2 XML and the siteId, which is used as the file name for the stored data

  2. FGSES converts the content from XML to CSV and writes it to SmartSite's AFS final grade location

  3. FGSES finishes the request by responding with a http status code

  4. GB2IA inspects the response from FGSES and finished the initial client request

    1. The client inspects the the response and if there are no errors, the client opens up the FGT in an pop-up window
