Creating Custom Discovery Locations

In addition to adding content from one of Voyager's standard location types, administrators can add Custom Discovery Locations if they have been previously registered. 

Before you can add a Custom Location to the Index, you will need to

1. Create the Custom Location
2. Register the LocationFactory

Creating Custom Locations

To create a custom location, you will need to implement three classes:

• Location - each location must have a unique name. 
• DiscoveryRunner
• LocationFactory

Three samples from the Voyager are shown below.

Sample 1 - Earthquakes Location

This is an example that connects to an RSS feed

• EarthquakesLocation.java
• EarthquakesRunner.java
• EarthquakesLocationFactory.java

Sample 2 - Autonomy IDOL Location

A custom location for Autonomy IDOL service.

• AutonomyLocation.java
• AutonomyRunner.java
• AutonomyLocationFactory.java

Sample 3 - MyFolder Location

This is an example with a more complex JSON configuration

• MyFolderLocation.java
• MyFolderRunner.java
• MyFolderLocationFactory.java

Registering the LocationFactory

• Each LocationFactory class needs to be registed with the Java ServiceLoader (for more information, see META-INF/services/voyager.api.discovery.location.LocationFactory)
• Re-start Voyager so that it reads Registered Custom Locations 

Adding Custom Locations in Voyager 

Once custom locations are registered and Voyager has read them at startup, you can add them to the index.
