Sri Lanka National Client Registry IG Capability Statement

Implementation Guide Version: 0.1.0
FHIR Version: 4.0.1
Supported Formats: SHALL support json
Published on: 2026-12-31
Published by: Sir Lanka Ministry of Health

Note to Implementers: FHIR Capabilities

SHALL Support the Following Implementation Guides

http://ig.hiu.lk/fhir/clientregistry/ImplementationGuide/fhir.lk.clientregistry

FHIR RESTful Capabilities

Mode: `server`

The Client Registry supports a limited number of interactions and has special operations.

Capabilities by Resource/Profile

Summary

The summary table lists the resources that are part of this configuration, and for each resource it lists:

The relevant profiles (if any)
The interactions supported by each resource (Read, Search, Update, and Create, are always shown, while VRead, Patch, Delete, History on Instance, or History on Type are only present if at least one of the resources has support for them.
The required, recommended, and some optional search parameters (if any).
The linked resources enabled for _include
The other resources enabled for _revinclude
The operations on the resource (if any)

Resource Type	Profile	R	V-R	S	U	C	Searches	`_include`	`_revinclude`	Operations

Extended Operations

Conformance	Operation	Documentation
SHALL	$getIdentifierList	Request for a list of identifiers (across source systems) for a particular Client.
SHALL	$linkClients	This operation is used to link two Clients. Linking is an internal procedure where the system applies some confirmation and 'links' resource instances with an internal mechanism. The 'link' is not disclosed or part of any FHIR resource, but a user can confirm the linkage by searching with the identifier list operation.
