Writing Code that Implements the Asset Synchronization Cycle

Key things about the Asset Integration Cycle algorithm:

• Can execute a mode=‘all’ once. If there is any error then it will attempt to retry on the next interval.
• Can execute a mode=‘delta’ forever. It will also handle any kind of error by retrying on the next interval
• AI_InitializeAssetMetaData, AI_PollAssetMetaData and AI_AcknowledgeAssetMetaData can fail on the OLSA side due to network issues, SkillSoft-hosting maintenance windows, and so forth
• Polling interval must be in the order of minutes

The Asset Integration Cycle must be in the order of hours. Completing the Process File step is specific to the LMS. Before you apply changes, see Checking Status.

Recommended algorithm

set mode to ‘all’ or ‘delta’

set format to ‘aicc’ or ‘scorm’, etc…

loop (forever) { 

  try {

    handle = AI_InitiateAssetMetaData (mode, format)

    loop (forever) {

      sleep X minutes // polling interval

      try {

        resp = AI_PollForAssetMetaData(handle)

        exitloop // exit polling loop

      } catch (DataNotReady) {

        // stay in polling loop

      }

    }

    Retrieve file via URL in resp

    Process file

    AI_AcknowledgeAssetMetaData(handle)

    if mode==all then exitloop // performing 'all' exit main loop

  } catch (AnyException) { 

    try {

      AI_AcknowledgeAssetMetaData(null)

    } catch (AnyException) {

      // ignore

    }

  }

  sleep N hours // main Asset Integration Cycle interval

}
