SNOMED CT Snapshot REST API 
Lightweight mongo server with a rest API for SNOMED CT Snapshot views, powered by the MEAN stack, http://mean.io/, (Node.js, Express & MongoDB).
How to install
Clone this project into the server, by using:
git clone https://github.com/IHTSDO/sct-snapshot-rest-api.git
In the "sct-snapshot-rest-api" folder use Node.js to install all dependencies:
sct-snapshot-rest-api: $ npm install
And then run the server:
sct-snapshot-rest-api: $ node app.js
IMPORTANT: This API needs to have local access to the MongoDB server where the terminology data has been loaded into. The SNOMED CT data for the mongo instance can be obtained via your local National Resource Center (info in http://www.ihtsdo.org/members).
Once you have the SNOMED CT Files in RF2 format (standard release files) you can create a JSON file for importing into Mongo using this project:
https://github.com/IHTSDO/rf2-to-json-conversion
Access the server
