Class MRL

java.lang.Object

ai.djl.repository.MRL

public final class MRL
extends java.lang.Object

The MRL (Machine learning Resource Locator) is a pointer to a Metadata "resource" on a machine learning Repository.

Each mrl references a single metadata file (parsed to Metadata and the collection of artifacts located within it. Those artifacts all share the same groupId and artifactId, but can differ based on the name and properties.

The mrl consists of three different properties:

• type - The resource type, e.g. model or dataset.
• application - The resource application (See Application).
• groupId - The group id identifies the group publishing the artifacts using a reverse domain name system.
• artifactId - The artifact id identifies the different artifacts published by a single group.

Method Summary

Modifier and Type	Method and Description

java.lang.String	getGroupId() Returns the groupId.
static MRL	model(Application application, java.lang.String groupId, java.lang.String artifactId) Creates a model MRL with specified application.
java.lang.String	toString()
java.net.URI	toURI() Returns the URI to the metadata location (used for Repository implementations).
static MRL	undefined(java.lang.String groupId, java.lang.String artifactId) Creates a dataset MRL with specified application.
