DGI Actions

Introduction

Provides a framework to support minting and deletion of identifiers either locally or with external services.

Requirements

This module requires the following modules/libraries:

• Islandora

Installation

Install as usual, see this for further information.

Configuration

This module and its submodules come with no configuration out of the box. Below is the steps for configuring the included dgi_actions_ark_identifier.

Entity configuration

The main configuration overview for all entities used within the module is located at admin/config/dgi_actions.

Data profile configuration

Data profile entities contain data used when building up a request to a service. These values are retrieved from the entity and are passed along with an HTTP request. EZID provides a good example of how this is used.

1. Create a new data profile: admin/config/dgi_actions/data_profile/add.
2. Give the data profile a name.
3. Select the entity and bundle for which the data will be retrieved from. In this example choose node and Repository Item.
4. Select the DataProfile plugin that's being used. In this example choose ERC.
5. For the three ERC fields choose which fields to map from.
6. Save the data profile.

Service data configuration

Service data entities contain configuration used for interacting with external APIs.

1. Create a new service data: admin/config/dgi_actions/service_data/add.
2. Give the service data a name.
3. Select the ServiceData plugin that's being used. In this example choose EZID.
4. Fill in the required fields that is provided by the EZID plugin.
5. Save the service data.

Identifier configuration

Identifiers tie everything together. In the event ServiceData and DataProfiles are being used they store references to the configured entities from above. Similarly, they store where the minted identifier is going to be placed.

1. Create a new identifier: admin/config/dgi_actions/identifier/add.
2. Give the identifier a name.
3. Select the entity and bundle for which the data will be stored on. In this example choose node and Repository Item.
4. Select the field in which the identifier will be stored in. For the example choose whichever field you want.
5. Choose the ServiceData being used for the request from the dropdown if needed. For the example choose the one created above.
6. Choose the DataProfile being used for the request from the dropdown if needed. For the example choose the one created above.
7. Save the identifier.

Action configuration

An action is required for each identifier being minted and optionally deleted.

1. Create a new action: admin/config/system/actions.
2. Under Create an advanced action choose either the mint or delete action to be configured. For the example choose Mint ARK EZID Identifier.
3. Choose the identifier entity that the action will trigger and save.
4. Repeat the above and instead choose Delete ARK EZID Identifier and save.

Context configuration

Drupal's Context module is used in conjunction with conditions and entity hooks to handle minting and deleting with a custom condition to check if a entity already has a persistent identifier.

1. Create a new context: admin/structure/context/add.
2. Give it a name and optionally fill out the other fields and save.
3. Configure the conditions required for an identifier to be minted. For the example create two conditions: Node Bundle and Entity Has Persistent Identifier. Configure the Node Bundle condition to look for the Repository Item bundle and Content from hook. Configure the Entity Has Persistent Identifier condition to use the Identifier created above and Content from hook. Negate this condition such that it will only mint if it does not already exist.
4. Choose require all conditions.
5. Add a reaction choose Mints an identifier.
6. Under entity choose whatever the mint action created above was called.
7. Repeat the above and instead choose the Deletes an identifier reaction and conditions that satsify deletion. Normally this would be just removing the negation on Entity Has Persistent Identifier.

New Integrations

To create a new identifier minting integration at least a MintIdentifier action is required.

Optionally a DataProfile plugin, a ServiceDataType plugin and a DeleteIdentifer action can be created if required.
