Registries
HCX registries will act as a source of truth for participant information on the platform. These may be extended from/link to already existing registries in the ecosystem, e.g. registry may extend from National Health Facility Registry provided by NHA. The benefit of extending from an existing registry would be:
Easy maintenance of base data at the source registry
The extended registry only needs to maintain additional/supplementary information pertaining to its use case
Better interoperability
Keeping with the key design principles listed above, registries on HCX will strive to be minimalistic, self-maintainable, support non-repudiability, accessible through OpenAPIs, Extensible and evolvable, and designs for data privacy and security. All registries on the HCX platform will minimally provide the following APIs:
Create
Update
Search
Delete
Please note that onboarding of the actors in the registry will take place through workflows defined by domain groups and may change over time, therefore the access to the data modification APIs would be controlled by the HCX instance provider and used as part of the onboarding process.
Participating Organisations/Systems Registry
This registry stores key details about the participants on the exchange who can exchange data through it. It may link with data on the HFR registry and will have fields necessary to facilitate claims data exchange with providers. Proposed attributes of the registry are:
participant_code
Machine-readable unique identifier of the participant, generated by the HCX instance.
String
Mandatory
Unique across installations - namespaced as participant_code@hcx_instance_code
linked_registry_codes
Identifier of the participant in other registries. Each identifier shall be in a “normalised” notation having the structure “identifier@registry”, where registry is a unique code for the registry system and identifier is the unique id of the participant in that registry system.
Ex: facility001@hfr - to link the provider record to HFR record.
The list of supported registry codes (e.g. hfr, rohini, etc) should be a configuration at the HCX instance level.
List
Optional
scheme_code
name/code of the scheme provided by the payor. scheme_code is mandatory for all participants of type “Payor”.
If a payor has multiple schemes, there will be multiple entries in the registry for the same payor (participant) - one entry per scheme.
If the payor wishes to use a single entry for all its schemes, the schem_code value should be set to “default”.
String
Optional
participant_name
A human-readable name for the participant
String
Mandatory
Unique within the HCX instance context
roles
Roles assigned to the participant as per the definition in the domain specifications. This will be used for access control.
String
Mandatory
address
The physical address of the participant including its geolocation
JSON structure
Optional
primaryEmail
Primary Email id for claims related communication
String
Optional
additionalEmail
Additional/alternative email ids of the participant for backup/recovery purposes. Maximum of 2 email addresses are allowed.
Array
Optional
Maximum 2
primaryMobile
Primary mobile number for claims related communication
String
Mandatory
additionalMobile
Additional/alternative mobile numbers of the participant for backup/recovery purposes. Maximum of 2 email addresses are allowed.
String
Optional
Maximum 2
phone
Landline number of the participant
String
Optional
Maximum 3
status
Current status of the participant on the instance. Can be:
Created (Not verified yet)
Active
Inactive
Blocked
String
Mandatory
signing_cert_path
URI/file path to the JWT signing certificate
String
Optional
encryption_cert
URI/file path to encryption certificate
String
Mandatory
endpoint_url
Default endpoint to make API calls
String
Mandatory
payment_details
Default payment details:
UPI ID, or
Ac Number + IFSC Code
JSON Structure
Optional
User Registry
While the exchange protocol by itself may not need to focus on the human user (as the exchange is between systems), operational management of the exchange infrastructure may require administrative infrastructure that may necessitate a registry for operational users from organizations running HCX as well as participating organizations. Following are the proposed attributes for the User registry:
user_id
Machine-readable user-id as the unique identifier generated by the HCX instance.
String
Mandatory
Should be unique across the installation
user_name
Human readable use name - something like email id
String
Mandatory
Name spaced and unique within a context
Can be system generated
pin
Identification pin if needed to be set
String
Optional
mobile*
Mobile number of the user
String
Conditionally optional, if any other identifier like Aadhar is provided
email*
Email Id of the user
String
Conditionally optional, if any other identifier like Aadhar is provided
Roles
An array of additional roles (apart from being a base/citizen user which is assigned to every user by default) assigned to the user
String
Mandatory
May have different roles against different tenants in advance setups
Roles should be a subset of the ones defined in reference to Master Data in the platform
Tenant
Base tenant of the admin user
String
Mandatory
Represents key operational geography and function of the user
linkedUserId
User ID in the source system
String
Optional
Following OpenAPI 3.0 document describes these registries and the associated APIs.
