odata-v4-service-metadata

Using this module you can generate a service metadata document response from a simple JSON format, an advanced schema JSON format or an Edmx instance created with odata-v4-metadata.

Basic usage

Use the simple JSON format and convert your metadata JSON to a service metadata document. ```javascript var ServiceMetadata = require('odata-v4-service-metadata').ServiceMetadata; // $metadata express.js route app.get('/odata/\\$metadata', ServiceMetadata.defineEntities({

namespace: 'Default',

containerName: 'Container',

entities: [

{

name: 'Kitten',

collectionName: 'Kittens',

keys: ['Id'],

computedKey: true,

properties: {

Id: 'Edm.String',

Name: 'Edm.String',

Age: 'Edm.Int32',

Lives: 'Edm.Int32',

Owner: 'Edm.String'

},

annotations:[

{ name: 'UI.DisplayName', value: 'Meww' },

{ property: 'Id', name: 'UI.ReadOnly', value: 'true' },

{ property: 'Title', name: 'UI.DisplayName', value: 'Meww Meww' },

]

}

]

}).requestHandler()); ```

Advanced usage

Use a schema JSON, which is more verbose, but you can customize the metadata in a more advanced way. ```javascript var ServiceMetadata = require('odata-v4-service-metadata').ServiceMetadata; var schema = require('./schema'); var serviceMetadata = ServiceMetadata.processMetadataJson(schema); var serviceMetadataDocument = serviceMetadata.document(); ``` An example schema JSON looks like this
