'Frankenstyle' refers to the naming convention that is used to uniquely identify a Moodle plugin based on the type of plugin and its name.

Martin Dougiamas is credited with inventing the word 'frankenstyle' to describe this naming system which was invented by Petr Skoda. (It is a great word!)


Frankenstyle names have a prefix and then a name, separated by an underscore.

  • The prefix is determined by the type of plugin. For example, the prefix for an activity module is mod.
  • The name is the name of the plugin. (Plugin names are always made of lower-case letters.)

So the frankenstyle name for the quiz module is mod_quiz.

Plugin types

  • Activity modules: [mod] => /mod
  • Admin reports: [report] => /admin/report
  • Assignments: [assignment] => /mod/assignment/type
  • Authentication plugins: [auth] => /auth
  • Blocks: [block] => /blocks
  • Course formats: [format] => /course/format
  • Course reports: [coursereport] => /course/report
  • Database field types: [datafield] => /mod/data/field
  • Database presets: [datapreset] => /mod/data/preset
  • Editors: [editor] => /lib/editor
  • Enrolment plugins: [enrol] => /enrol
  • Filters: [filter] => /filter
  • Grade export plugins: [gradeexport] => /grade/export
  • Grade import plugins: [gradeimport] => /grade/import
  • Grade reports: [gradereport] => /grade/report
  • Local plugins: [local] => /local
  • Messaging consumers: [message] => /message/output
  • Mnet services: [mnetservice] => /mnet/service
  • Plagiarism plugins: [plagiarism] => /plagiarism
  • Portfolio plugins: [portfolio] => /portfolio
  • Question behaviours: [qbehaviour] => /question/behaviour
  • Question formats: [qformat] => /question/format
  • Question types: [qtype] => /question/type
  • Quiz reports: [quiz] => /mod/quiz/report
  • Repository plugins: [repository] => /repository
  • SCORM reports: [scormreport] => /mod/scorm/report
  • Themes: [theme] => /theme
  • User profile fields: [profilefield] => /user/profile/field
  • Webservice protocols: [webservice] => /webservice
  • Workshop allocation strategies: [workshopallocation] => /mod/workshop/allocation
  • Workshop evaluation plugins: [workshopeval] => /mod/workshop/eval
  • Workshop grading forms: [workshopform] => /mod/workshop/form

To get a definitive list, do print_object(get_plugin_types()); in a Moodle 2.x install.


Frankenstyle is used in:

Table names

All table names for a plugin must begin with its frankenstyle name (after the standard Moodle table prefix).

Examples: mdl_mod_quiz, mdl_mod_quiz_attempts


All capabilities for a plugin use the frankenstyle name, except with a / instead of a _.

Example: mod/quiz:viewattempt

Other places (TODO)

Please add more as they come up.
