Design - Making Question Set Editor QuML Compliant

Background

While comparing the existing inQuiry question and question set metadata and schema with QuML schema we found few difference which is mentioned in the below sheet:

Question & Questionset QuML compliant difference

Also currently we are not storing some of the metadata properties with language code. Details of those properties are mentioned in the below sheet:

Question and Questionset Property Object datatypes

Problem Statements

How to make existing metadata properties QuML complaints :-

Multi-lingual support

Some of the properties are supposed to be stored in i18nData form i.e language code and it’s value

example :

en: ‘What is the capital of India?’

But currently with the editor we are able to store this data in string format

Simply storing it as:

‘What is the capital of India?’

The properties of question set which is to be stored in i18n form are:

instructions (text)
feedback (currently not in use)
hints (currently not in use)

The properties of question which is to be stored in i18n form are:

body (text or text+ image)
answer (text or text + image)
hints (text)
solutions (text or text+ image/video)
interactions (text or text+ image)
instructions (currently not in use)
feedback (currently not in use)

Solution For multi-Lingual support:

For adding instructions in question set with language code, we will add a language drop down field in the question set form.

The default value of the drop down should be ‘English’ this default value and range of options will be set from form configuration where we will give default value as ‘English’ and other languages can be added to it in the configuration:

{
	"code": "languageCode",
	"name": "Language Code",
	"label": "Select Language for instruction",
	"placeholder": "Select Language",
	"description": "It's the Language of instruction",
	"dataType": "text",
	"inputType": "select",
	"output": "identifier",
	"default": "en",
	"range": [{
			"identifier": "en",
			"label": "English"
		},
		{
			"identifier": "hi",
			"label": "Hindi"
		}
	],
	"editable": true,
	"required": false,
	"visible": true,
	"renderingHints": {
		"class": "sb-g-col-lg-1"
	}
}

Same config we will have in question creation page to have a language drop down field and based on selection we can transform the data while question creation/ update.

timeLimits

Time limits is currently being stored in the question set metadata in below format:

timeLimits: {
   "maxTime": "360",
   "warningTime": "120"
}

But as per the QuML schema it should be stored in this format:

timeLimits:
{
   questionset: {
           min: number,
           max: number
   },
   question: {
           min: number,
           max: number
   }
}

Solution for timeLimits

Timer feature is developed for complete question set and not for the individual question.

We can store the time limits as:

timeLimits:
{
   questionset: {
           min: number,
           max: number
   }
}

If the timer feature is developed for question in future we can store the timer data to question metadata as:

timeLimits:
{
   question: {
           min: number,
           max: number
   }
}

Note: The above field is part of the common form so in the form config we will be using maxTime and warningTime and in editor code we will handle maxTime with max and warningTime with min.

responseDeclaration

Response Declaration is currently stored as below format but two properties are not allowed in it: maxScore and outcomes

"responseDeclaration": {
       "response1": {
           "maxScore": 1, // maxScore is not allowed here
           "cardinality": "single",
           "type": "integer",
           "correctResponse": {
               "value": "0",
               "outcomes": {
                   "SCORE": 1
               } // outcome is not allowed here, only property ‘value’ is allowed
           },
           "mapping": []
       }
   }

Solution for responseDeclaration

Instead of keeping maxScore and outcomes in responseDeclaration we should store it in responseProcessing as below:

responseProcessing: {
   "template": [
       "MAP_RESPONSE",
   ],
   "mappingConfig": [{
       "SCORE": 1,
       "outcomes": {
           "SCORE": 1
       }
   }]
}

For newly created question responseDecleration will be like this:

"responseDeclaration": {
       "response1": {
           "cardinality": "single",
           "type": "integer",
           "correctResponse": {
               "value": "0",
           },
           "mapping": []
       }
   }

and responseProcessing will have above format.

For old question we do either the data migration and update the question with above mentioned format,

or making editor intelligent to check if the question have responseProcessing . If responseProcessing does not exists, update the question’s responseDeclartion and responseProcessing format on question update.

Open Questions for no data migration:-

Is updating the question format to be done on question set update( having n number of questions in question set) or to be updated on each question edit and update in Practise Question set?
How the editor and player should handle the old questions which are in review/live status?

Editor opened by reviewer in review mode: In this format is the editor supposed to take care to pick the data from responseDeclaration and not from responseProcessing
What happens if reviewer tries to publish the question which is not having responseProcessing?

media

In question metadata question contains media in this format:

"media": [{
   "id": "do_2136952965043896321346",
   "type": "image", //instead of ‘type’ it should be ‘mediaType’
   "src": "/assets/public/content/assets/do_2136952965043896321346/mountain.jpeg",
   "baseUrl": "https://dev.inquiry.sunbird.org"
}]

New format to be used is:

"media": [{
   "id": "do_2136952965043896321346",
   "mediaType": "image",
   "src": "/assets/public/content/assets/do_2136952965043896321346/mountain.jpeg",
   "baseUrl": "https://dev.inquiry.sunbird.org"
}]

Open Question:

Can we do migration for old questions for this change of type to mediaType ?
