Plugin Requirements

1. The name of the Plugin should match the format FooSource.
2. The Plugin should implement a FooSource model and a corresponding controller (FooSourcesController).
   
   1. This model should belongTo OrgIdentitySource.
   2. The controller should extend SOISController.
   3. When a new Org Identity Source is created, a skeletal row in the corresponding foo_sources table will be created. There is no add operation or view required. The skeletal row will point to the parent Org Identity Source.
   4. When an Org Identity Source is edited, the entry point to the Plugin will be foo_source/foo_sources/edit/#. This will be called immediately after the parent Org Identity Source is created.
   5. Note OrgIdentitySource has a hasOne (ie: 1 to 1) relationship with FooSource.
   6. The table foo_sources should include a foreign key to org_identity_sources:id.
      1. Other tables used by the plugin should reference foo_source:id.
3. The Plugin should also implement a model named FooSourceBackend.
   1. The backend is responsible for the implementation of the backend search and retrieval capabilities.
      1. The raw record returned by the retrieve() function should not change if the underlying backend record has not changed. Registry uses the raw record to determine when the related Org Identity record must be updated.
      2. The Plugin should support mail (email address) as a searchable attribute. This capability is used by Enrollment Flows in various configurations, see Integration With Enrollment Flows, below.
      3. As of Registry v3.1.0, Plugins may also implement getChangeList(), which determines the set of changed records for a given time period. When supported, OIS sync processes in Update Mode will run more efficiently.
         1. As of Registry v3.2.0, if the forcesyncorgsources task is used, getChangeList() cannot be used.
         2. Because getChangeList() is designed to facilitate updating existing records, backends should only return IDs for records that were updated or deleted. The function should not return IDs for records that were added, as the Sync Job will separately determine which records were added (using the backend's inventory() call), and if getChangeList() returns these IDs they may be processed twice.
      4. See also Supported Attributes, below.
   2. This model should extend OrgIdentitySourceBackend, and implement the abstract functions defined in the parent model (see app/Model/OrgIdentitySourceBackend.php).
   3. Note that the Plugin configuration for FooSource will be available to the backend in $this->pluginCfg.
4. Registry will automatically track the current backend data via the org_identity_source_records table.

Supported Attributes

The Org Identity Source Backend is expected to return both a raw record (directly representing the backend datasource), and a formatted record. The formatted record is expected to represent an OrgIdentity, in typical Cake array format, along with its associated Models. The Backend may return the following supported attributes:

Attribute	Multi-valued?	Required?	Notes
Address	Yes	No	See note below.
AdHocAttribute	Yes	No
EmailAddress	Yes	No	See note below.
Identifier	Yes	No	Does not automatically include the unique key (SORID). See note below.
Name	Yes	No	At least one Name must be returned, and exactly one Name must be flagged primary. See note below.
OrgIdentity.affiliation	No	No	Possible values may vary by CO; see CoExtendedType::definedTypes
OrgIdentity.title	No	No
OrgIdentity.o	No	No
OrgIdentity.ou	No	No
OrgIdentity.valid_from	No	No	Must be in UTC time, and database format, eg via strftime("%F %T", ...)
OrgIdentity.valid_through	No	No	Must be in UTC time, and database format, eg via strftime("%F %T", ...)
TelephoneNumber	Yes	No	See note below.
Url	Yes	No	See note below. Available from Registry v3.1.0.

Example

$myData = array(
  'OrgIdentity' => array(
    'title' => 'Researcher',
    'o' => 'University of Impossible Equations',
    'ou' => 'Department of Timey Wimey Stuff'
  ),
  'Name' => array(
    array(
      'given' => 'Pat',
      'family' => 'Lee',
      'type' => 'official',
      'primary_name' => true
    )
  ),
  // Note below here are multi-valued arrays
  'Identifier' => array(
    array(
      'identifier' => 'plee@university.edu',
      'type' => 'eppn',
      'login' => true
    )
  ),
  'EmailAddress' => array(
    array(
      'mail' => 'plee@university.edu',
      'type' => 'official',
      'verified' => true
    ),
    array(
      'mail' => 'plee@socialemail.com',
      'type' => 'personal',
      'verified' => false
    )
  )
);

Groupable Attributes

Is order to support Group Mappings for Organizational Identity Sources, the Plugin must implement two functions in the Backend file.

1. groupableAttributes() defines the set of attributes the Plugin knows about that may be used for generating group memberships. This may be a static list of attributes, or (as of v3.1.0) it may be dynamically determined based on a given instantiation (via the configuration available in $this->pluginCfg).
2. resultToGroups() converts a raw result into an array of attribute value/pairs. Note the array is not itself the group mapping, but rather the relevant attributes that will be used by the core code to determine if any group membership match. (This way the Plugin does not need to worry about parsing the mapping configuration.)

Example

public function groupableAttributes() {
  return array(
    'title' => _txt('fd.title');
  );
}

public function resultToGroups($raw) {
  // The core code will use this data to determine if the configured 
  // OIS Group Mapping rules are matched.

  return array(
    'title' => array(
      array(
        'value' => 'Professor of Mysterious Events',
        'valid_from' => '2017-08-01 00:00:00',
        'valid_through' => '2018-07-31 23:59:59'
      );
    );
  );
}

Integration With Enrollment Flows

Organizational Source Plugins can be integrated with Enrollment Flows by way of Enrollment Sources. See the Enrollment Sources documentation for an overview of the various modes and how they are used.

Authenticate Mode

Most modes are supported using the interfaces described in Plugin Requirements, above. However, Authenticate mode requires OIS Plugins to implement an additional interface. (Plugins should use this interface to support Authenticate mode, and not the general Enrollment Flow Plugin interface, since this interface will automatically handle configuration checking and plugin ordering.)

The Enrollment Flow will hand off control during the selectOrgIdentity step to the entry point foo_source/foo_source_co_petitions/selectOrgIdentityAuthenticate/#/oisid:## (where # is the relevant CO Petition ID, and ## is the Org Identity Source ID).

The easiest way to implement this is for the Plugin itself is to extend CoPetitionsController. This way, most of the overhead of processing the request will be handled for you, and your plugin need only implement the function execute_plugin_selectOrgIdentityAuthenticate, where control will be passed. Once your plugin is finished, it should return control to the flow by redirecting back to the main flow, using the URL passed in $onFinish. The redirect URL is also available in the view variable $vv_on_finish_url.

// Plugin/FooSource/Controller/FooSourceCoPetitionsController.php 
 
App::uses('CoPetitionsController', 'Controller');
class FooSourceCoPetitionsController extends CoPetitionsController {
  public $name = "FooSourceCoPetitions";
  public $uses = array("CoPetition",
                       // Your plugin will most likely need to use OrgIdentitySource to
                       // create the OrgIdentity
                       "OrgIdentitySource");
 
  /**
   * @param  Integer $id CO Petition ID
   * @param  Array $oiscfg Array of configuration data for this plugin
   * @param  Array $onFinish URL, in Cake format
   * @param  Integer $actorCoPersonId CO Person ID of actor
   */

  protected function execute_plugin_selectOrgIdentityAuthenticate($id, $oiscfg, $onFinish, $actorCoPersonId) {
    // Do some work here, then redirect when finished.
    // By default, Exceptions will be caught further up the stack, though you could catch them here.
 
    $myId = result_of_some_work();
 
    // Create an Org Identity
    $this->OrgIdentitySource->createOrgIdentity($oiscfg['OrgIdentitySource']['id'],
                                                $myId,
                                                $actorCoPersonId,
                                                $this->cur_co['Co']['id'],
                                                $actorCoPersonId);

    // Create some history
    $this->CoPetition->CoPetitionHistoryRecord->record($id,
                                                       $actorCoPersonId,
                                                       PetitionActionEnum::IdentityLinked,
                                                       _txt('pl.foosource.linked', array($myId)));
 
    $this->redirect($onFinish);
  }
}

Standard MVC rules apply.
