Add a Flask API to serve the data format

[LaRiffle]

Having an API to serve this files that represents the FHIR format would be very valuable. One direct application would be for our interface fhir-ball to fetch the Resource structure on which the user will do the mapping.

Beyond that, it allows external user to access the standard in their preferred format (json, yml, etc) in a very simple way, and without having to worry about about the latest release.

A good implementation would be to do this with Flask.

Can you specify, what the API input and the output would be ? (And illustrate it with a short query template pls)

Store
I think it would be like this:

The input is:

• the type of request ('store' for accessing the store)
• the ouput type ('yml', 'json')
• the name of a FHIR Ressource (ex: "Patient")

The output is:

• The content of the associated file (ex: https://github.com/arkhn/fhir-store/blob/master/yml/Identification/Individuals/patient.yml) (note that you must infer the path)

api.get('api.arkhn.com/store/yml/Patient')

Returns

resourceType: "Patient"
identifierlist::Identifier:
active:
...

Also, the API could be useful to serve mapping file as well:

Mapping

The input is:

• the type of request ('mapping' for accessing the mapping rules)
• The database (ex: 'CW')
• the ouput type ('yml', 'json')
• the name of a FHIR Ressource (ex: "Patient")

The output is:

• The content of the associated file (ex: https://github.com/arkhn/fhir-mapping/blob/master/CW/resources/Identification/Individuals/patient.yml) (note that you must infer the path)

api.get('api.arkhn.com/mapping/CW/yml/Patient')

Returns

info:
source_table: 'ICSF.PATIENT'
fhir:
resourceType: 'Patient'
identifierlist::Identifier:
_join:
_type: 'OneToOne'
_args: ['ICSF.PATIENT.NOPAT=ICSF.PATCOMP.NOPAT']
...

Should be case insensitive I think
