What is a Resource


A "resource" is anything which can be described and referenced. A resource may be conceptual, physical or digital. For example, a person is a physical resource, data is a digital resource and an annotation is a conceptual resource. Typically, only digital resources can be delivered to you and only information about physical and conceptual resources can be conveyed to you.

When a resource is described it is assigned a unique identifier. The value of this identifier is a required part of every description. The identifier is used to reference the resource, both externally and by other resources. See Creating a Resource ID for more details on Resource Identifiers.
