Sunbird Content Specification for Deep Linking

Intent

Need to create an unified deep linking 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 deep links as part of their implementation.

Approaches

Approach 1 : (Deeper Integration)

Deep Link 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

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

Tighter coupling for bazaar apps to be reliant on Sunbird APIs.

Necessary for bazaar apps to understand the content metadata. Could mean a development effort for these players

Any service disruptions,outage could spell trouble for these apps and also could potentially ending these apps taking a hit in terms of ratings.

Approach 2 : (Lighter Integration)

Deep Link provides basic information such as content do_id, telemetry context information & artifactUrl and mimeType.

Bazaar Apps can launch the artifactUrl directly based on mimeType.

Pros :
Least Effort in integrating the deep link for bazaar apps.

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

Sample Deep Linking Uri:
cpi://play?resourceId=<param-value>&referrerPackageId=<param-value>…..

Params	Description	Data type
resourceId	identifier of the resource to be served in bazaar apps	String
collectionId	CollectionID of textbook,course	String
referrerPackageId	package details of referrer app	String
batchId	BatchId if it is trackable collection	String
mimeType	Content MimeType	String
vendorCode	Vendor ID to validate the referrer	String
contentCategory	contentCategory	String
