A very simple example Orbit adapter implementation for Ember Data that's hard coded with a single Orbit.LocalStorageSource. Note that the Orbit schema could easily be auto-generated from DS models. Also, DS relationships would have to be mapped to Orbit links (and the adapter would need to call `link` / `unlink` methods on Orbit stores).

orbit-ember-data-adapter.js

export default DS.Adapter.extend({
  orbitSource: undefined,

  init: function() {
    this._super();
    Orbit.Promise = Ember.RSVP.Promise;

    // TODO - autogenerate schema from DS models
    var schema = {
      idField: 'id',
      models: {
        contact: {
          attributes: {
            firstName: {type: 'string'},
            lastName: {type: 'string'},
            email: {type: 'string'},
            notes: {type: 'string'}
          },
          links: {
            phoneNumbers: {type: 'hasMany', model: 'phoneNumber', inverse: 'contact'}
          }
        },
        phoneNumber: {
          attributes: {
            name: {type: 'string'}
          },
          links: {
            contact: {type: 'hasOne', model: 'contact', inverse: 'phoneNumbers'}
          }
        }
      }
    };

    var orbitSource = new Orbit.LocalStorageSource(schema);
    this.set('orbitSource', orbitSource);
  },

  find: function(store, type, id) {
    return this.get('orbitSource').find(type.typeKey, id);
  },

  findAll: function(store, type) {
    return this.get('orbitSource').find(type.typeKey);
  },

  createRecord: function(store, type, record) {
    var serializer = store.serializerFor(type.typeKey);
    var data = serializer.serialize(record, {includeId: true});
    return this.get('orbitSource').add(type.typeKey, data);
  },

  updateRecord: function(store, type, record) {
    var serializer = store.serializerFor(type.typeKey);
    var data = serializer.serialize(record, {includeId: true});
    return this.get('orbitSource').update(type.typeKey, data);
  },

  deleteRecord: function(store, type, record) {
    var serializer = store.serializerFor(type.typeKey);
    var data = serializer.serialize(record, {includeId: true});
    return this.get('orbitSource').remove(type.typeKey, data);
  },
});
