Description:

The OpenIMIS HF object (from the openimis-be-location_py module) was mapped to the FHIR Location resource.

Notes / Assumptions:

The endpoint uses the UUID as a primary key
The current version of mapping will be focused on aspects of claiming.
In the current version of the openimis-be-location_py missing services layer which can be used to perform operations (CRUD - Create, Read, Update, Delete) on entities. That's why the current version of API use directly database layer manager for managing the HealthFacility objects. This leads to differences between the operation between legacy and new OpenIMIS, for instance, the update operation doesn't create the database row with a history of the object and the delete operation permanently remove the object from the database.
legalForm - missing in the current version of the HealthFacility model (from the openimis-be-location_py module). That's why the current version of API doesn't cover that field. Attribute needs to be nullable type in the Database Schema.
locationid - missing in the current version of the HealthFacility model (from the openimis-be-location_py module). That's why the current version of API doesn't cover that field. Attribute needs to be nullable type in the Database Sche

Color	Description
	Mapped - the final choice, the most suitable choice
	Need to be found the best place for the field (not mapped currently)
	Currently not important - not mapped

Mapping:

OpenIMIS field	DB type	FHIR field	Description	Note	STPH	Mapping status
HfID	int	Identifier				This is the Database ID and should be used only internally
HfUUID	uniqueidentifier	Identifier	The unique identifier used as PK for FHIR			mapped
HFCode	nvarchar(8)	Identifier				mapped
HFName	nvarchar(100)	name				mapped
LegalForm	FK(tblLegalForms)		G: Government C: Charity D: District organization P: Private organization	The FHIR Location object don't contains that kind of information. If this information is valuable for external systems then we can add FHIR extension (if needed).		Will be added after when the final approach will be established. That field isn't supported by the current version of openimis-be-location (0.0.1).
HFLevel	char(1)	type	C - health center H - hospital D - dispensary			mapped
HFSublevel	FK(tblHFSublevel)		I: Integrated R: Reference N: No Sublevel	The FHIR Location object don't contains that kind of information. If this information is valuable for external systems then we can add FHIR extension (if needed).		Will be added after when the final approach will be established. That field isn't supported by the current version of openimis-be-location (0.0.1).
HFAddress	nvarchar(100)	Address				mapped
LocationId	FK(tblLocations)	partOf - Reference(Location)		The FHIR Location will be used to represent the tblHF and tblLocations. The FHIR location.mode field can be used to distinguish between those object.		Will be added after when the final approach will be established. That field isn't supported by the current version of openimis-be-location (0.0.1).
Phone	nvarchar(50)	telecom				mapped
Fax	nvarchar(50)	telecom				mapped
eMail	nvarchar(50)	telecom				mapped
HFCareType	char(1)		I - In-Patient O - Out-Patient B - both	The FHIR Location object don't contains that kind of information. If this information is valuable for external systems then we can add FHIR extension (if needed).		Will be added after when the final approach will be established. Currently for creating a new object is used the default value based on the module configuration.
PLServiceID	FK(tblPLServices)			If needed we can add the FHIR extension, try to use the "Location.endpoint" to represent this field or try to use the FHIR HealthcareService.		Will be added after when the final approach will be established. That field isn't supported by the current version of openimis-be-location (0.0.1).
PLItemID	FK(tblPLItems)			As above.		Will be added after when the final approach will be established. That field isn't supported by the current version of openimis-be-location (0.0.1).
AccCode	nvarchar(25)		Account Code	I'm not sure if this information should be available for external systems. If needed we can add this information to the "location.description" or we can add the FHIR extension.		Will be added after when the final approach will be established.
OffLine	bit			I'm not sure but this is probably used to determine the source of row (offline/online app). Probably information isn't valuable for external systems.
ValidityFrom	datetime		Audit information. More information can be found here (on page 113): https://github.com/openimis/openimis_docs/blob/master/specs/Web%20application%20-%20Functional%20Design%20Specification.pdf	This information are valuable for OpenIMIS but I probably not required by external systems.
ValidityTo	datetime
LegacyID	int
AuditUserID	int
RowID	timestamp			I'm not sure but this is probably some unique value used to distinguish database rows. Probably not useful for external systems.

Note:

the tblHF has a relation with tblHFCatchment, the information from tblHFCatchment can be added as FHIR extensions (if needed)

Endpoint specification:

Example of endpoint URL:

http://127.0.0.1:8000/api_fhir/Location/

Supported HTTP operation:

CREATE - used to create new FHIR Location (HF). List of supported fields can be found in the table which shows the mapping between OpenIMIS and FHIR. Should be used the POST HTTP method and the body as JSON representation (example can be found below).
Note:
- the `offline` model attribute isn't currently covered by the current API. By the default value is False (can be modified by the module configuration).
- the `care_type` model attribute isn't currently covered by the current API. By the default value is "B" - both (can be modified by the module configuration).
- the `validity_from` attribute is set as the current value of date when the object is created
- the `audit_user_id` - the user which interact with the FHIR API is the `TechnicalUser` (Backend security - Models and Concepts) which hasn't representation in tblUsers. That's why the value of the `audit_user_id` attribute is set based on the following algorithm:
  1) Try to get that value from the 'auditUserId' query parameter
  2) If missing get that value then use the value from the module configuration (by default 1)
READ - by default return list of all available resources. To fetch information about a specific object you should add the primary key to URL for instance:
http://127.0.0.1:8000/api_fhir/Location/01DB0819-69F6-44F9-BF3D-0BCC5D4803E2
, where "01DB0819-69F6-44F9-BF3D-0BCC5D4803E2" is the value of the primary key. Should be used the GET HTTP method.
UPDATE - update the value of the specific object. List of supported fields can be found in the table which shows the mapping between OpenIMIS and FHIR. Should be used the PUT HTTP method and the body as JSON representation (example can be found below). The requested URL needs to point to a specific object to do that you should add the primary key to URL for instance:
http://127.0.0.1:8000/api_fhir/Location/01DB0819-69F6-44F9-BF3D-0BCC5D4803E2
, where "01DB0819-69F6-44F9-BF3D-0BCC5D4803E2" is the value of the primary key.
Note:
- the `offline` model attribute isn't updated
- the `care_type` model attribute isn't updated
- the UPDATE operation will update the specific row of the database and doesn't create the history of changes (like in the legacy OpenIMIS)
DELETE - the operation can be used to remove the specific object from the database. Should be used the DELETE HTTP method. The requested URL needs to point to a specific object to do that you should add the primary key to URL for instance:
http://127.0.0.1:8000/api_fhir/Location/01DB0819-69F6-44F9-BF3D-0BCC5D4803E2
, where "01DB0819-69F6-44F9-BF3D-0BCC5D4803E2" is the value of the primary key.
Note:
- the DELETE operation will permanently remove the row from the database
