Purpose

This WS allows to create Specimen entity by employees without submitting Encounter Data Package.

Specification

Key points

1. Only authenticated and authorized employee with appropriate scope can create a Specimen.

2. Request should be signed with DS.

3. The specimen is created asynchronously

4. The specimen can be created both for persons and for prepersons.

Processing

1. Save signed content to media storage, in the bucket pointed in MEDIA_STORAGE_SPECIMEN_BUCKET chart parameter

2. Generate accession_identifier number:

   1. Generate requisition number (see Human readable requisition number) based on the specimen id. Note: requisition number should be unique for each specimen and should not match with number of another entities. So, if generated number match to existing in DB - it should be regenerated

   2. Encode and set it into $.accession_identifier attribute

3. Set display_value for:

   1. registered_by attribute

   2. managing_organization attribute

   3. collection.collector attribute, only if type is employee (not patient)

4. Set context, received_time, status_reason, collection.procedure to null

5. Set subject with hashed mpi identifier

6. Save data to specimens collection in DB according to /wiki/spaces/SPECIMEN/pages/17548214286 RC.__Specimen data model_EN

7. Save link from media storage to the $.signed_content_links field in specimens collection

8. Create job and return it’s id.
