I would like the plug-in architecture for question types to become convenient as that for activity modules. I want it to be possible to simply drop the code for new question types in the right directories. Moodle should then recognise, install and use them automatically.

I think this mechanism should work exactly like that for modules. That way we don't need to reinvent the wheel. Here are the details:

1) create a table 'questiontype' with fields 'id', 'name', 'version'. The first 12 entries should be created so that the ids match the current qtype ids.

2) every questiontype has a file version.php giving the version of the code. The Moodle update script should check this version number against that in the 'questiontype' table and trigger a database update in the same way as it currently does for modules and blocks. Each questiontype will have a directory 'db' with the database sql and php scripts.

3) the import/export code should have the questionype specific code in a separate file for each questiontype. This code should extend the questiontype class to provide extra methods needed by the import/export code. Questiontype authors will be required to provide these files for their questiontype if they want their questions to participate in import/export.

4) the same as in 3) applies to the backup/restore code and the report plug-ins. Again questiontypes that don't provide the required methods will be ignored by these scripts.

5) each questiontype will use its own language file to be named 'qtype_...' where ... is the questiontype name. The questiontype code can use these strings as usual with get_string('stringname', 'qtype_...') once these files have been dropped into the right language directory.

Did I forget anything?
