Authority vs Repository
An authority and a repository definition are sometimes used interchangeably in IPS and
have different meanings at other times. The following points expound upon the definitions
and clarify their usage.
An authority is a person, groups of persons, or a corporation that publishes a package.
A repository is a location from where packages are downloaded from . The location constitutes an address (URL) of a machine .
A repository can contain packages from many authorities. Conversely many repositories can contain packages from a single authority.
A default or preferred authority is similar to a default catalog. Any package chosen for installation is first searched for in the preferred authority's catalog. This package may be available for download from different repositories.
You can have many repositories and one default authority. In this case, the default authority becomes the default repository.
If there is only one default repository, it also becomes the default authority.
