Hub Terminology

Package: A collection of entities (artifacts, applications, datasets, configuration) to add to CDAP. A package is identified by a name and version, and can be tagged with one or more categories. Each package must contain a specification, and may contain resources.

Package Specification: Defines metadata about the package, such as display label, description, creation time, and CDAP compatibilities. It contains a list of actions that must be performed to install the package. Each action corresponds to a wizard in the installation process.

Package Resource: A file that can be used during the installation process. It can be a configuration file, a JAR, or data that should be loaded into a dataset. Resources are referenced by name in the actions defined in the package specification.

Catalog: The catalog is a list of all the packages in the Hub. The catalog contains metadata about each package.
