Launchpad Registry

The registry is a core domain that most all Launchpad applications require. The code is primarily located in lp.registry and lp.services.mailman.

Pillars

Pillars are distributions, projects and project groups. They share a common set of features.

• Name Blacklist: The rules that prevent names for being used either because of application restrictions or organisational ownership.
• Announcements: They appear on pages and in RSS.
• Application Configuration: The pages that allow owners to set where services are hosted and configure Launchpad usage.

Projects

Projects commonly produce software, art, or some work that can be used. Projects have maintainers, and drivers, but are shared by communities who make contributions according to their own interests.

• Licenses: The terms that govern the use, distribution and modification

  of the work produced by the project.
  

• Commercial subscriptions: The rules that permits proprietary projects to use Launchpad.
• Project groups: A grouping of projects that provides aggregated views of bugs, blueprints, and answers. The group drivers are drivers of the projects.

Distributions

Ubuntu's releases are mirrored by other sites.

• Mirrors: CD and archive mirrors of distribution releases.
• Distribution mirror prober: The process that checks the freshness of mirrors.

Series, Milestones, and releases

Projects and distributions have series of milestones that mark progress toward a goal (releases). Project releases are often associated with tarballs or installers.

• Series: A sequence or grouping of goals that constitute an planned effort to produce a finished work.
• Milestones: time-bases or feature-based goals.
• Releases: A completed goal that culminated in a release of files that may by finished or be in an alpha or beta state.
• Product release finder: A process to locates release files on remote sites and uploads them to Launchpad, possibly creating milestone and releases on series.
• timelines: A representation of series, releases, and timelines.
