oada-formats

This repo contains models for all formats whose format is known from a given media type. Each model consists of a module with validate(), schema(), and example() functions. Some base model types, e.g., JsonModel, are available for use.

oada-foramts exposes a Formats class that acts as a repository of models. The model() function is a factory function for various mediatype models. The use() function can be used to extend the model types and model repository. See valleyix-formats for an example. oada-formats comes with OADA defined formats pre-loaded by default.

Installation

1npm install oada-formats

Usage

1var Formats = require('oada-formats');
2
3var formats = new Formats();
4formats.use(require('your-favorite-model=package'));
5
6formats
7  .model('application/vnd.oada.bookmarks.1+json')
8  .then(function(model) {
9    return model.validate(model.example());
10  })
11  .then(/* success */)
12  .catch(Format.ValidationError, function(error) {
13    console.log(error.errors);
14  });

1var Formats = require('oada-formats');
2
3var formats = new Formats();
4
5var model = formats.model('application/vnd.oada.link.1+json');
6
7model.examples().then(console.log);
8model.example('default').then(console.log);
9model.schema().then(console.log);

Adding JSON Models

The JsonModel can be used to add new json models easily. [valleyix-formats][valleyix-formatas] is a good example.

1. Build a directory structure where each folder in the hierarchy is the next word of the format's mediatype, split on '/' and '.'.
2. At the root of the directory structure there must be an index.js that exposes a plain old object. It may have any property names, however, JsonModel will load the values of properties examples and schema as the format's examples and schema respectively. An array of function(data) implementing custom validation rules can be stored under the addtionalValidators property. index.js may expose the plain old object, a promise of a plain old object, or a plain old object with promises at its first level of properties. Therefore any type of asynchronous loading can be done, e.g., http or database.
3. If there is not an examples property then any js or json file in an examples directory at the root of the mediatype directory structure will be loaded in as the examples. The example name will be the filename less it's file extension.
4. If there is not a schema property then a schema.js or schema.json file at the root of the mediatype directory structure will be loaded in as the schema.
