What does it do?

As stated on the Github repository, the plugin “emits events from the Moodle Logstore as xAPI statements.” For those that don’t know, the Moodle Logstore is a log of activities within Moodle. When you view a course, complete a quiz, or grade a student, a log of that activity is recorded in the Logstore. The plugin uses these logs to produce xAPI statements and then sends (emits) them to an LRS (Learning Record Store).

How does it work?

The plugin is made up of three parts, an Expander, a Translator, and an Emitter. Every log entry goes through each of these parts in a six-step process before finally reaching the LRS (see below).

  1. The plugin passes the log entry from the logstore_standard_log to the Expander.
  2. The Expander expands the log entry with data from your Moodle database.
  3. The plugin passes the expanded event from step 2 to the Translator.
  4. The Translator translates the expanded event to xAPI/TinCan recipe options.
  5. The plugin passes the translated event from step 4 to the Emitter.
  6. The Emitter constructs the translated event as an xAPI/TinCan statement and emits it to the LRS.

Potential privacy issues

This system sends logging information over the internet. This would include information about the user, links to their profile, and information of courses completed. It would be recommended to have a secure connection between your website and LRS if they are not within a private network.

    Hi Mouaici, the entry point is classes/log/store.php#L113 (https://github.com/xAPI-vle/moodle-logstore_xapi/blob/master/classes/log/store.php#L113). In future, please post questions to Github where you'll get a faster response (https://github.com/xAPI-vle/moodle-logstore_xapi/issues).

    Hi Ryan,
    For some reason my plugin is not sending ANYTHING (as far as I can tell) to the Watershed LRS. My Activity Provider is correct because Tin Can Launch works with it. Can you please help me debug, or what could be the issue? Thank you.

    Hi Ryan and everyone,
    I am working behind institute proxy and trying to use this plugin in Moodle but no data is being transmitted to Learning Locker. I can see in the database that the table mdl_logstore_xapi_log is capturing events. I have also tried to send statements to Learning Locker directly which works. I followed the steps available in the website of h2tlabs. Please guide me.

    Hi everyone
    Have you planned to emit events for badges issuing?
    Thanks

    Hello Emmanuel - we have been maintaining the plugin via Github because Moodle doesn't allow automatic commits to the plugin site. We currently do not have badging events translating to xAPI statements, but we do have instructions on how to add new events. Feel free to submit it as a new issue and maybe even submit a PR if you feel comfortable. Thanks for your interest!

    Hi, this is a really awesome plugin. Does it work for moodle 4.0?
  • David Pesce

    Hello Tien - the plugin does work with 4.0, but it needs some updates in order to work perfectly. Plans are in the works to migrate this repository to another developer who can update and maintain it more frequently.

    This plugin is very useful. Are there any plans to include quiz response data and h5p activity response data in xAPI statements?
  • Laura Cray

    Great plugin. One question - is it possible to get an answered statement for the Choice and Lesson activities as well?
