Metadata can be used to describe elements of a content package in its manifest file. Metadata allows learning resources to be found when stored in a content package or in a repository. When a learning resource is intended to be reusable, it is a best practice to describe it with metadata. Describing learning objects with metadata facilitates their search and discover across systems.
Metadata can be context-independent or context-dependent. Context-independent metadata usually refers to immutable metadata that describes digital assets, content objects, etc. Context-dependent metadata usually refers to metadata that makes sense only in the context of a particular context organization.
