How to define the schema and context for a DIAL?

How to define the schema and context?

• There are two ways to define and upload the schema in blob.

  1. Fork sunbird-dial-service repo

  2. Create the your own repo and follow the same structure of schemas folder as in sunbird-dial-service repo.

Steps:

1. Create the new folder inside schemas folder with the context-name. e.g. we have the context name content and collection.

2. Create the file context.json and schema.json inside context folder.

   Open

   

   
   Sample schema.json

   { "$id": "file:./schemas/<context_name>/schema.json", "$schema": "http://json-schema.org/draft-07/schema#", "title": "<context_name>", "type": "object", "properties": { "<attribute_1>" : { "type": "string" }, "<attribute_2>" : { "type": "array" }, "<attribute_3>" : { "type": "array" }, "<attribute_4>" : { "type": "string" } } }

   Sample context.json

   { "@context": { "schema": "http://schema.org/", "<attribute_1>": { "@id": "schema:name#<attribute_1>", "@type": "schema:name" }, "<attribute_4>": { "@id": "schema:name#<attribute_1>", "@type": "schema:name" }, "<attribute_2>": { "@id": "schema:name#<attribute_2>", "@type": "@id", "@container": "@list" }, "<attribute_3>": { "@id": "schema:name#<attribute_3>", "@type": "@id", "@container": "@list" } } }

    

3. Upload schema and context in blob storage using jenkins job
   Deploy/Kubernetes/DialUploadSchemas - Configure the schemas folder path in jenkins job to upload all the available schema and context to blob storage.
   
   Configure the dial_plugin_container_name in devops private repo. e.g.

   dial_plugin_container_name: "sunbird-dial-dev"

Configure the dial_service_schema_base_path in devops private repo. e.g.

1. Verify the uploaded schema/context by accessing the following URL format

   e.g. for collection

2. Set the schema path in sunbird-dial-service application.config with the blob storage path and do the dial-service deployment.

e.g.
