Join For FreeAn External Data Services (EDS) plugin in IBM Content Navigator (ICN) is used to integrate external data sources with ICN. An EDS plugin allows ICN to retrieve data from external data sources, such as databases or web services, and display it in ICN. The EDS plugin interface defines the methods that ICN uses to communicate with the plugin, such as initializing the plugin, performing queries, and retrieving data.
The following is an overview of the design considerations for developing an EDS plugin in ICN:
- Determine the Data Source: The first step is identifying the data source the EDS plugin will access. This could be a database, web service, or custom API.
- Define the Plugin Interface: The EDS plugin needs to implement the EDS plugin interface, which defines the methods that ICN uses to communicate with the plugin. The plugin interface provides methods for initializing the plugin, performing queries, and retrieving data.
- Implement the Plugin Logic: The plugin logic should be designed to retrieve the required data from the data source and transform it into a format that ICN can consume. Depending on the data source, this may involve implementing custom data access logic, data mapping, or data transformation logic.
- Define the Plugin Configuration: The EDS plugin needs to define a configuration interface that specifies the configuration options for the plugin. This includes parameters such as the data source URL, credentials, and any custom configuration options.
- Implement the Plugin Configuration: The plugin configuration should be designed to validate the configuration options and ensure that they are correctly specified. Depending on the complexity of the plugin configuration, this may involve implementing custom validation logic or custom user interface elements for configuring the plugin.
- Package and Deploy the Plugin: Once the EDS plugin is implemented, it needs to be packaged and deployed to ICN. The plugin can be packaged as a JAR file, which can be uploaded to the ICN server and registered as a plugin. The plugin can be deployed either globally or to specific ICN applications, depending on the requirements.
The design considerations will vary depending on the data source, the complexity of the plugin logic, and the requirements of the application.
Below is one of the sample scenario for the usage of External Data Services in IBM Content Navigator:
Auto-populating metadata values based on the selection of a property value can be achieved using an External Data Services (EDS) plugin in IBM Content Navigator (ICN). Here are the general steps to implement this:
Step #1. Define the Metadata Property: First, define the metadata property in the ICN system. This property will be used to store the metadata value that will be auto-populated. The metadata property can be determined using the ICN administration console.
Step #2. Implement the EDS Plugin: Develop an EDS plugin that will be used to auto-populate the metadata value. The plugin should implement the EDS plugin interface and should handle the event when the user selects the property value. The plugin should retrieve the metadata value from the external data source based on the selected property value and set the metadata property value accordingly.
Step #3. Register the EDS Plugin: Register the EDS plugin with the ICN system. This can be done using the ICN administration console or by deploying the plugin to the ICN server.
Step #4. Configure the Auto-population: Configure the auto-population of the metadata value based on the selected property value. This can be done using the ICN administration console. Configure the property mapping between the selected property value and the metadata property. Specify the EDS plugin to be used for auto-population.
Step #5. Test the Auto-population: Test the auto-population of the metadata value by selecting the property value and verifying that the metadata value is populated correctly in the IBM Content Navigator application.
