Sunbird Content Specification for Bazaar Apps

Intent

Need to create an interface for enabling Access to Content on Sunbird across different apps like Read Along,Games etc.

Note: Assumption of this specification is based on the apps being able to support these intents as part of their implementation.

Documentation is categorised into multiple sections:

  • WorkFlow

  • Vendor Registration of Apps to Sunbird

    • Global Vendor Registration API

    • Local Vendor Registration by Deep Linking

  • Technical Specification for third party apps

    • Param Data Supported

    • Summary Event Spec

    • API Documentation

    • Intent Handling

  • Approaches


Work Flow

Registration of External Apps

Global Registration

 

{ identifier: "", name: "", logo: "", appName: "", packageId: "", target: { mimeType : [], contentType : [], .... // All content attributes }, appDetails: { organization: "" } }

 

 

Local Registration By Deep Link (Only Restricted to that particular device)

Registering by Deep link inside Sunbird

sunbird://register?name: "Google Corporation", logo: "https://<domain-url>", appName: "Google Bolo", packageId: "com.google.bolo",target:”{}”,appDetails:”{}”

 

 

 


Sunbird Third Party App Interaction

{ referrerPackageId : "com.google.bolo", referenceID : "App generated Code", mimeType : "", vendorCode : "", contentUrl : "", profileContext: "{handle:'',avatar:''}" }

 

 

{ "edata": { "type": "", "mode": "", "starttime": Long, "endtime": Long, "timespent": Double, "pageviews": Long, "interactions": Long, "envsummary": [{ "env": String, "timespent": Double, "visits": Long }], "eventssummary": [{ "id": String, "count": Long }], "pagesummary": [{ "id": String, "type": String, "env": String, "timespent": Double, "visits": Long }] } }

 

 

 


Vendor registration of Apps to Sunbird

  • Global Vendor Registration API

Each Vendor can be registered as part of Global Configuration for Sunbird to have app links being enabled.

{ identifier: "", name: "", logo: "", appName: "", packageId: "", target: { mimeType : [], contentType : [], .... // All content attributes }, appDetails: { organization: "", id: "", version: "" }, vendorCode: "" // Internally assigned }

Vendor CRUD API (or) Form Configuration Supported.

  • Local Vendor Registration by Deep Linking
    Enabling of Deep link in Sunbird for local registration restricted to device.
    Device hears for deep links to register vendor apps locally (Restricted to particular device).

    Steps

    • Vendor app needs to call a deep link of Sunbird app.

    • Sunbird App as part of handling deep link will try to persist vendor information locally on app’s data.

    • Any subsequent invocation of intent from Sunbird will show globally registered apps for Sunbird along with locally registered apps in devices.

deeplink Url :

sunbird://register?name: "", logo: "", appName: "", packageId: "",target:”{}”,appDetails:”{}”

Parameter

DataType

Description

Parameter

DataType

Description

name (M)

String

Name of the vendor

logo (M)

String

App logo Url

appName (M)

packageId (M)

String

PackageID of the app

target (M)

String

Targeted content query

appDetails (O)

String

App details

extra (O)

String

Misceallaneous Information to be sent

 


Approaches

Approach 1 : (Deeper Integration)


Intent provides basic information such as content do_id, telemetry context information.

Targeted Application need to fetch the data from platform. Understand the Content Metadata and play the content.

Targeted Application need to respond back with Summary Data

Params

Description

Params

Description

resourceID

Content ID of the resource

context

Context of the play - like did, sid, uid etc

Pros

It can enable bazaar apps to index the content in their own environment.

It could open up the Sunbird APIs for most of the bazaar players.

Cons

Data to be sent might be huge

Spec is rigid. If the spec changes there can be inconsistency between various version of both apps

Approach 2 : (Lighter Integration)

Intent provides basic information such as content do_id, context information & artifactUrl and mimeType.

Bazaar Apps can launch the artifactUrl directly based on mimeType.

Params

Description

Params

Description

resourceID

Content ID of the resource

context

Context of the play - like did, sid, uid etc

mimeType

Mime type of the content

artifactUrl

The URL to download the content

 

Pros
Least Effort in integrating the Intent for bazaar apps.

Need to develop a secure mechanism to serve only sun bird specific resources.

Cons

Data to be sent might be huge

Spec is rigid. If the spec changes there can be inconsistency between various version of both apps

Intent provides the basic information such as content URL, mimeType & user/session context.

Params

Description

Params

Description

resourceID

Content ID of the resource

context

Context of the play - like did, sid, uid etc

mimeType

Mime type of the content

contentUrl

The public Sunbird content url or a dial url (https://<domain>/content/v1/read/do_xxxx => https://<domain>/dial/XC40VV)

Pros

  1. The spec doesn’t need to change if more content metadata needs to be sent

  2. The integration apps need to understand our content model and can also index the content in their apps

Context Information

Following are the contextual params passed to the reader app

  1. Device ID

  2. User ID

  3. Session ID

  4. Collection ID

  5. Batch ID

  6. Reference ID

Technical Specification for Third Party Apps

Params

Description

String

referenceID

Reference ID to be sent back to sunbird app

String

mimeType

https://github.com/sunbird-specs/Telemetry/blob/main/v3_event_details.md/#summary

{ "edata": { "type": "", // Required. Type of summary. Free text. "session", "app", "tool" etc "mode": "", // Optional. "starttime": Long, // Required. Epoch Timestamp of app start. Retrieved from first event. "endtime": Long, // Required. Epoch Timestamp of app end. Retrieved from last event. "timespent": Double, // Required. Total time spent by visitor on app in seconds excluding idle time. "pageviews": Long, // Required. Total page views per session(count of CP_IMPRESSION) "interactions": Long, // Required. Count of interact events "envsummary": [{ // Optional "env": String, // High level env within the app (content, domain, resources, community) "timespent": Double, // Time spent per env "visits": Long // count of times the environment has been visited }], "eventssummary": [{ // Optional "id": String, // event id such as CE_START, CE_END, CP_INTERACT etc. "count": Long // Count of events. }], "pagesummary": [{ // Optional "id": String, // Page id "type": String, // type of page - view/edit "env": String, // env of page "timespent": Double, // Time taken per page "visits": Long // Number of times each page was visited }] } }

All the reader apps need to send summary data back to Sunbird app via intent data.

The third party apps should do a HTTP GET call on the contentUrl parameter sent via the intent data

GET intentdata.contentUrl Headers { X-App-ID: <ID of the App>, X-App-Version: <Version of the App>, X-Device-ID: <Device Id> }

Response Data Structure

{ "id":"api.content.read", "ver":"v1", "ts":"2021-02-10 04:27:14:674+0000", "params":{ "resmsgid":null, "msgid":"90e184d1-c52c-106b-c410-6a168900ef05", "err":null, "status":"success", "errmsg":null }, "responseCode":"OK", "result": { "content": ContentModel } }

Object Types

Intent Handling

  • Need to implement an activity which is capable of calling API and read the content metadata to launch the content in their respective apps. Following is the API request,response structure to be adhered to.

  • Need to create an intent filter in Android Manifest as follows :

  • <activity android:name="com.example.ExampleActivity" android:label="@string/title_example" > <intent-filter android:label="@string/play_view_web_example"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <!-- Accepts URIs that begin with "http://sunbird.staginged.in/play” --> <data android:scheme="https" android:host="sunbird.staginged.in" android:pathPrefix="/play" /> </intent-filter> <intent-filter android:label="@string/play_view_app_example"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <!-- Accepts URIs that begin with "example://play” --> <data android:scheme="example" android:host="play" /> </intent-filter> </activity>


    Implement Activity as follows

  •  

    @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent intent = getIntent(); String action = intent.getAction(); Uri data = intent.getData(); <!-- Trigger the Business Logic of App --> }
