Data Models

Validation for standard data models

This repository provides examples and validators for data models that we want to share through different eHealth projects

JSON schema docs: http://json-schema.org

Attention developers!

This is open software. If you need realistic data for your tests you can either forge them or generate them automatically with the command line tool (see below). Improving the generator is also a way to improve the data model.

Schema Domain

Until such a time upon which we decide on something better, the current schema domain is schema.ehealthafrica.org and the current stable version is 1.0. e.g:

https://schema.ehealthafrica.org/1.0/Image.json#

API

validate

Add the dependency from the module, then use the provided validate method. For example if you want to validate a Person object:

var dataModel = require('data-model');
var person = { ... };
var errors = dataModel.validate(person);

If the object is valid, errors should be null.

generate

Given an optional list of model names (and count), generate an instance with pre-filled pseudo data:

var dataModel = require('data-model');
dataModel.generate('driver', 1);
// =>
// { driver:
//   [ { doc_type: 'driver',
//       version: '1.0.0',
//       forename: 'Wade',
//       surname: 'Jacobi',
//       email: '[e-mail]',
//       phone: '1-264-961-1978' } ] }

CLI

A command line interface to the generate function (stringified as JSON) can be useful for generating fixtures, for example:

data-model --model driver --count 1

Yields:

{
  "driver": [
    {
      "doc_type": "driver",
      "version": "1.0.0",
      "forename": "Jeremie",
      "surname": "Bayer",
      "email": "[e-mail]",
      "phone": "[phone] x656"
    }
  ]
}

See data-model --help for further usage.

For client side code

A bundled version is available in the dist/ folder. The files there have been built with Browserify using the --standalone option, so they will expose a global dataModel object.

Remember to run npm run build before tagging a new release of this code in order to update the distribution files.
